Mumbai Trans Harbour Link

The Mumbai Trans Harbour Link also known as the Sewri Nhava Sheva Trans Harbour Link, is an under-construction 21.8 kilometres (13.5 mi), freeway grade road bridge connecting the Indian city of Mumbai with Navi Mumbai, its satellite city. When completed, it would be the longest sea bridge in India.[3] The bridge will begin in Sewri, South Mumbai and cross Thane Creek north of Elephanta Island and will terminate at Chirle village, near Nhava Sheva. The road will be linked to the Mumbai Pune Expressway in the east and to the proposed Western Freeway in the west. The sea link will contain a 6 lane highway,[4][5][6] which will be 27 meters in width, in addition to two emergency exit lanes,[7] edge strip and crash barrier.[8][9]

Location

The project is estimated to cost ₹14,262 crore (US$2.0 billion). The MMRDA awarded contracts for the project in November 2017; construction began in April 2018, and is scheduled to complete within four-and-a-half years. The MMRDA estimates that 70,000 vehicles will use the bridge daily after it opens.[10]

History

Transportation and traffic planning for Greater Bombay was commissioned to Wilbur Smith and Associates in mid-1962. The firm's report, based on extensive studies conducted over 18 months, was handed over to the Union Ministry of Transport on 19 December 1963. Among other projects, the report proposed the construction of a sea link, known as the Uran Bridge, to connect Mumbai with the mainland near the town of Uran. However, Smith was unsure of the link's feasibility. Citing poor traffic expectations in Uran even in 1981, his report advised a more detailed study of this connection and recommended waiting until "the Trans-Thana area develops further and more community services are extended to Uran."[11] In 1973, the Vashi Bridge linking Mankhurd in Mumbai with Vashi in Navi Mumbai was opened.

First attempt

The first concrete attempt to build the sea link was made in 2004, when Infrastructure Leasing & Financial Services (IL&FS) submitted a proposal to implement the project on a build, own, operate and transfer (BOOT) basis. The Maharashtra State Road Development Corporation (MSRDC) also submitted a counter proposal. However, the IL&FS proposal was side-lined by the government, for undisclosed reasons.[12]

Second attempt

Another attempt was made in 2005, when the MSRDC invited bids for the project. But bids submitted by the Ambani brothers was considered to be unrealistic.[13] A consortium of the Anil Dhirubhai Ambani Group company Reliance Energy (REL) and Hyundai Engineering & Construction quoted a concession period of nine years and 11 months against 75 years quoted by Mukesh Ambani's Sea King Infrastructure (the only other short-listed bidder left, after Larsen & Toubro-Gammon and IFFCO opted out). The REL-Hyundai consortium was initially disqualified at the technical bid stage as Hyundai did not meet the criteria of $200 million net worth specified in the bid document. However, the consortium challenged the disqualification in the Supreme Court, and the Court granted them 90 days to submit their bid that ended on 15 December 2007. The consortium eventually won the bid in February 2008.[14] However, the MSRDC was not sure about viability of the low concession period. The MSRDC felt that the concession periods were "unrealistic" and that both bids "seemed frivolous in nature".[12]

Third attempt

The Government of Maharashtra called for a fresh bids for the project in 2008. However, none of the 13 companies that had shown interest, submitted bids.[13] The media criticized the political feud between the ruling Nationalist Congress Party (NCP) and Congress coalition, as being responsible for slowing "down the pace of Mumbai's development". The city's two infrastructure agencies, the MSRDC and the Mumbai Metropolitan Region Development Authority (MMRDA), under the NCP and Congress respectively, were both planning to construct the MTHL at the same time. The project underwent two failed rounds of tendering under the MSRDC, and was stuck for nearly two years (between 2009 and 2011), before the state government decided to hand over the mandate to MMRDA. Following the decision, the MSRDC asked MMRDA to pay ₹25 crore (US$3.5 million) if it wanted access to any of the studies on the project conducted by the former. After the MMRDA was tasked with executing the MTHL, the MSRDC took up the expansion of the Vashi Bridge by adding six more lanes to ease congestion at the entrance to Navi Mumbai. However, the MMRDA refused the MSRDC's request to allocate funds for the expansion of bridge, as the former believed that the expansion would divert some ridership from the MTHL.[15]

Fourth attempt

The MMRDA appointed Arup Consultancy Engineers and KPMG to conduct the techno-economic feasibility of the MTHL in August 2011.[13] The project will be based on a public-private-partnership model.[16] The project received clearance from Chief Minister Prithviraj Chavan on 22 October 2012.[17] The Times of India described the MTHL's delay as being "symbolic of all that's wrong with infrastructure planning and implementation in Mumbai". The paper also stated that a project being "on the drawing board after more than forty years would be in the realm of fiction in any other country".[18]

Flamingos and other migratory birds at the Mahul-Sewri mudflats

The project received environmental clearance from the Ministry of Environment and Forests (MoEF) on 23 October 2012. The Maharashtra State Road Development Corporation (MSRDC) had obtained clearance for the project in March 2005, but the certificate was valid only for 5 years and lapsed due to the delays in the bidding process. The MoEF laid down 11 conditions that the MMRDA had to follow. Some of the conditions were that the MMRDA put up noise barriers, replant five times the number of mangroves destroyed, not carry out dredging or reclamation, use construction equipment with exhaust silencers and work in consultation with the Bombay Natural History Society to minimize the impact on migratory birds.[19][20][21] Environmental activists are opposed to the clearance. They point out there was no public hearing following the second application for environmental clearance. They believe that the sea link is not allowed as per the new Coastal Regulation Zone (CRZ) notification of 2011. Activists also claim that the sea link would damage a huge mudflat and mangrove tract towards Sewri and Nhava which is a habitat for migratory birds like flamingos.[22] MMRDA plans to construct sound barriers on the bridge so that it does not affect the flamingo habitat at Sewri. The Department of Atomic Energy (DAE) has directed MMRDA to construct a six-km long view barrier to cut the view of Bhabha Atomic Research Centre (BARC).[23] The MTHL received coastal regulation zone clearance from the MoEF on 19 July 2013.[24]

On 31 October 2012, the Department of Economic Affairs (DEA) granted in-principle approval for the MTHL.[25] The DEA recommended granting ₹1,920 crore (US$270 million) with a concession period of 35 years for the project.[26] In the first meeting, between MMRDA and DEA officials in September 2012, the ministry had asked the authority to treat the sea link as a road and reduce the proposed concession period from 45 years to 30 years. They also expected an internal rate of return of 15% for the project. However, the MMRDA wanted a higher rate as they claimed the project was very risky. An internal rate of return of 17% was agreed upon. The termination clause in the concession agreement comes into effect after 30 years into the concession period. The MMRDA can invoke the clause based on certain conditions such as the capacity being higher than expected. The conditions will be reviewed in the 20th year of the concession agreement.[27] The DEA is the first tier of the three-tier clearance process to get viability gap funding (VGF) for the project. The project must also receive approval from an Empowered Committee and finally from the Finance Minister.[19] On 9 November 2012, the State Government issued a state-support agreement and a toll notification for the project.[28] The empowered committee approved VGF for MTHL on 12 December 2012.[29] Finance Minister P. Chidambaram cleared the project on 18 January 2013.[30][31][32]

The Jawaharlal Nehru Port Trust (JNPT) asked the MMRDA to build the MTHL at a height of 51 metres, instead of the proposed 25 metres, for a span of 300 metres to accommodate its expansion plans for its fifth container terminal and to allow safe passage of bigger vessels. MMRDA expressed that a height of 51 metres would not be feasible as it would have a huge impact on the cost. However, MMRDA officials expressed willingness to raise the height of the bridge to 31–35 metres.[33][34] On 8 January 2012, Minister of State for Shipping and MP from South Mumbai, Milind Deora told reporters that JNPT would issue a No Objection Certificate to the State Government to go ahead with the project.[35][36][37]

In May 2012, the MMRDA shortlisted five consortia for the project: Cintra-SOMA-Srei, Gammon Infrastructure Projects Ltd.-OHL, Concessions-G.S. Engineering, GMR Infrastructure-L&T Ltd.-Samsung C&T Corpn., IRB Infrastructure Developers Ltd.-Hyundai, and Tata Realty and Infrastructure Ltd.-Autostrade Indian Infrastructure Development Pvt. Ltd.-Vinci Concessions Development V Pte Ltd.[38] None of the five shortlisted firms bid for the project by the deadline, which was extended 5 August.[39][40] IRB-Hyundai had announced their withdrawal from the bidding process, on 31 July 2013, citing "the government's apathy and unfriendly attitude towards investors wanting to develop capital-intensive infra projects".[41] Following the failure of the tender, the MMRDA decided to abandon the PPP model and instead implement the project on cash contract basis.[42]

In January 2013, the Central Government had sanctioned ₹1,920 crore (US$270 million), which was 20% of the project cost at the time, in viability gap for the MTHL.[43] Under the public private partnership (PPP) basis that the project was proposed to be implemented in,[44] the State Government would also contribute the same amount as the centre, while the remaining 60% would have been borne by the developer who won the bid.[19][44] The concession period would have been 35 years, which included the time-frame of 5 years for the construction.[45] However, the consortia shortlisted for the project were concerned that 15-20% of the projected traffic for the MTHL, was due to the proposed Navi Mumbai airport, which was heavily delayed. The MMRDA added provision for a shortfall loan to be made available from the central government if traffic is 20% under the estimate.[43]

Switch from PPP to cash-contract

The MMRDA decided to scrap the PPP model for the project in August 2013, and instead execute it on a cash-contract basis. Subsequently, the Japan International Cooperation Agency (JICA) expressed interest in providing funds for the project. In January 2014, Ashwini Bhide, MMRDA additional metropolitan commissioner, told The Indian Express that the state government had sent a formal proposal to the DEA for its approval to get funds from JICA.[46] In June 2014, Business Line reported that Jawaharlal Nehru Port Trust authorities had agreed to pick up a stake in the project.[47]

The project ran into a major hurdle in April 2015, when the forest advisory committee (FAC) of the MoEF withheld its clearance for the project stating that it affects "existing mangroves as well as the flamingo population". The project requires clearance from the Ministry as it will affect 38 hectares of protected mangrove forests and 8.8 hectares of forest land on the Navi Mumbai end. The sea link's starting point poses a threat to an estimated 20,000-30,000 lesser and greater flamingos and the mangrove habitat. The Sewri mudflats are home to 150 species of birds species, and is listed as an "Important Bird Area". The FAC instructed the state government to submit a study report on the project's impact on the flamingo population, and recommended that the government seek the help of either the Bombay Natural History Society (BNHS) or the Wildlife Institute of India, Dehradun to conduct the study. The cost of the study will be borne by the MMRDA, which will also have to come with safeguards to cause the least disturbance to the flamingos at Sewri.

On 17 April 2015, Union Minister of Road Transport and Highways Nitin Gadkari stated that he favoured the construction of a submarine tunnel instead of a sea link. Gadkari stated that the tunnel would cost less than a bridge (citing the example of the tunnel between Rotterdam and Belgium), and would also be aesthetically preferable as a sea link would obstruct the city's coastline. However, Gadkari clarified that the Union Government would accept the final decision made by the State Government on this matter.[48] Following a visit to China, Maharashtra Chief Minister Devendra Fadnavis announced on 20 May 2015, that the China Communications Construction Company (CCCC) had expressed interest in the MTHL project. According to Fadnavis, the CCCC will complete the project within 3–4 years of being appointed and will also provide 2% concessional funding for the project.[49][50]

In November 2015, the project was cleared by the Maharashtra Coastal Zone Management Authority (MCZMA).[51] In January 2016, the Forest Advisory Committee (FAC) granted forest clearance,[52] and the Experts' Appraisal Committee (EAC) attached to the MoEF granted CRZ clearance to the project.[53] The CRZ came with a rider requiring the MMRDA to spend at least ₹ 335 crore towards an "environment management programme".[54] In the same month, Fadnavis announced that the project had received all required clearances.[55]

In February 2016, JICA agreed to loan 80% of the total cost of the project to the State Government at an annual interest rate of 1-1.4%. The MMRDA will bear 1.2% of the project cost, and the remaining amount will be borne by the State Government.[56] As JICA was unwilling to loan directly to the state Government, the Union Government stood as a guarantor of the loan.[57] As part of the agreement between JICA and the State Government, 2 rescue lanes will be added to the proposed plan for the MTHL, and a 4 km stretch of the bridge will be constructed as a steel-only structure instead of previous plan to build a cement and concrete bridge. The use of steel on this stretch will raise the project cost by ₹ 4000 crores.[56] JICA formally approved the funding agreement on 9 May 2016, and the MMRDA began the bidding process the following day.[58] The MMRDA invited request for qualifications (RFQ) for civil construction of three packages - a 10.38-kilometre-long (6.45 mi) bridge section across the Mumbai Bay and Sewri interchange (₹ 6,600 crore), a 7.807-kilometre-long (4.851 mi) bridge section across Mumbai Bay and Shivaji Nagar,near Gavan inter change (₹ 4,900 crore) and a 3.613-kilometre-long (2.245 mi) viaduct including interchanges at SH 52, SH54 and NH 4B near Chirle, Navi Mumbai.[59] The MMRDA received 11 pre-qualification bids each for the first and second package, and 17 bids for the third package.[60][61] The agency stated that a single party would not be awarded the first and second packages together, although any other combination of the three packages would be permitted.[62]

The MMRDA appointed a consortium formed by AECOM Asia Co Ltd, Padeco India Pvt. Ltd, Dar Al-Handsah and TY Lin International as the general consultant for the project on 26 November 2016.[63] According to UPS Madan, Metropolitan Commissioner, MMRDA, "The General Consultants appointed for the MTHL project will engage in various activities such as to help MMRDA organise pre-bid meetings, examine bid documents, secure various permissions from government, semi-government, examine concept designs, monitor construction of the project and ensure quality of the work among other things."[64][65]

The MTHL received final environment clearance from the State Forest Department in May 2017.[66]

Prime Minister Narendra Modi laid the foundation stone for the project on 24 December 2016.[67] After evaluating the bids, in January 2017, the MMRDA shortlisted a total of 29 contractors for the three packages and floated tenders for the request for proposal (RFP) stage, the final stage of the bidding process. The agency fixed 5 April 2017 as the final date for submissions of the RFP bids.[68][69][70] The submission date was later postponed to 5 June.[71][72] However, the agency received over 3,000 queries from the short-listed bidders and was forced to postpone the date to 17 July in order to respond to all queries.[73]

The MMRDA applied for security clearance from the Union Home Ministry to carry out construction near the Bhabha Atomic Research Centre, the Mumbai Port Trust and the Jawaharlal Nehru Port Trust. These facilities have restricted areas that are covered by the Official Secrets Act. The MMRDA also submitted the names of all companies that bid for the project to the Home Ministry. The Ministry will grant clearance after consultations with other ministries such as the Foreign Ministry and the intelligence agencies.[74][75] The Home Ministry denied security clearance to a bid from Chinese consortium China Railway Major Bridge Engineering Group Limited in a joint venture with Gayatri Projects Limited, and also to a consortium of IL&FS Engineering Limited and Ranjit Buildcon Limited.[76] Both consortia were subsequently disqualified from the bidding process by the MMRDA. The MMRDA stated that Home Ministry had not provided the agency with any official reason for denying security clearance. IL&FS Engineering filed an appeal against the decision in the Bombay High Court on 18 July. The Court permitted IL&FS to submit its bid, subject to a final decision by the Court.[77]

The MMRDA received bids from 17 of the 29 short-listed contractors by the final bid submission date on 19 July 2017.[78][79][80] The agency stated that it would take one month to conduct technical evaluations of the bids and to award contracts.[81] On 9 November 2017, the MMRDA awarded contracts to a consortium of Larsen and Toubro (L&T) and Japan's IHI Corporation, a consortium of Daewoo and Tata Projects Limited (TPL), and L&T to construct the Sewri side of sea bridge, the Navi Mumbai side of sea bridge, and the bridge portion on land towards Chirle respectively.[82] The contracts between the MMRDA and the L&T-IHI Corporation consortium were officially signed on 27 December 2017. L&T was awarded ₹7,637.3 crore (US$1.1 billion) for the 10.38 km package 1 and ₹1,013.79 crore (US$140 million) for the 3.61 km package 3. The contract for the 7.807 km package 2 was signed with Daewoo and Tata Projects at cost of ₹5,612.61 crore (US$790 million) at a later date.[83][84]

Construction

The MTHL is a 6-lane freeway grade road bridge. It is 21.8 km long, including 16.5 km sea bridge and 5.5 km of viaducts on land on either end of the bridge.[85] The MTHL will be constructed in three sections:[86] About 4 km of the bridge length will be built with steel spans and the rest will use concrete. The MMRDA chose to use steel spans in these sections to eliminate the need to construct pillars to support the bridge which could hinder the movement of ships in the area. This 4 km section includes a 180 meter long steel span, which is the longest steel span in India. The shortest steel span on the MTHL is 110 meters long.[87][88]

Package Length Details Contractors Cost
1 10.38 km Bridge spanning across Thane Creek and Sewri Interchange. Larsen and Toubro and IHI Corporation ₹7,637.3 crore (US$1.1 billion)
2 7.807 km Bridge portion across Thane Creek and the Shivaji Nagar interchange. Tata Projects Limited and Daewoo E&C ₹5,612.61 crore (US$790 million)
3 3.613 km Viaducts and interchanges that connect MTHL with State Highways 52 and 54 and National Highway 4B at Chirle. Larsen and Toubro ₹1,013.79 crore (US$140 million)

The project requires 130 hectares of land. The City and Industrial Development Corporation (CIDCO) will contribute 88 hectares. The remaining land is privately owned.[89] According to MMRDA officials, land owners will be given the same compensation package as that given in the Navi Mumbai International Airport project.[90] Three hundred and twenty structures in Sewri were affected by the project, of which 250 properties were residential. The MMRDA provided resettlement for the affected people by offering accommodation in either Kanjurmarg or Kurla. The majority chose to relocate to Kanjurmarg.[91] The MMRDA also paid ₹6 lakh (US$8,400) each as compensation to 1,500 fishermen who were affected by the construction of the project.[92] In October 2016, the MMRDA agreed to pay MbPT a total of ₹ 1000 crores in instalments over the course of 30 years as rent for using the MbPT's land for construction of ramps for the MTHL on the Mumbai side.[93][94] The MMRDA will receive 27.2 hectares of land on the Sewri side of the MbPT, of which 15.17 hectares will temporarily be used for the casting yard.[95]

The MMRDA utilized a drone to carry out survey work for the MTHL. The drones were fitted with 360 degrees camera that provide up to 3 millimeter accuracy. The aerial survey takes less time than a regular survey, achieves greater accuracy and helps protect against false claims for compensation.[96] Over 1,000 boreholes were drilled to study the strata.[97] The MMRDA began conducting a geological survey for the project on 15 January 2018.[98] The project work will affect 1,635 trees of which 753 will be cut and the remaining 882 will be replanted at other locations. Most of the trees are located at Sewri and Vakola.[99][100]

Construction of the MTHL began in April 2018 with engineers collecting soil samples for soil testing at each location where piers will be built in Nhava Sheva.[101] MMRDA Metropolitan Commissioner R.A. Rajeev stated on 28 October 2018 that about 9% of the project work had been completed.[102][103] The first pier of the MTHL was built at Sewri on 18 May 2019.[104] The MMRDA stated that it had begun pre-segment casting work, a precursor to the superstructure for bridge deck construction, on 7 August. Each segment of the viaduct weighs 75 tonnes with dimensions 14.8m x 3.32m x 3.85m. Over 10,000 such segments will be cast.[105] The first segment will be erected on the Sewri side about 6 km into the sea. MMRDA officials announced the completion of the pre-casting work on 9 August. Officials also stated that they had completed the construction of 270 permanent piles, of which 177 were in the sea. The agency had also completed the construction of a 2 km long temporary access bridge.[106][107]

Casting for the first segment of Package 3 of the project began on 12 September 2019.[108] On the same date, MMRDA officials also stated that 20% of the total project work had been completed.[109] The project faced delays due the COVID-19 pandemic. Over 5,000 workers had been deployed on the project prior to the pandemic, but this was reduced to around 2,000 workers by June 2020.[110] An estimated 27% of the total project work had been completed by June 2020.[111]

Construction equipment used during the project are fitted with silencers to reduce the potential impact of noise on migratory birds such as flamingos. The project will also make use of reverse circulation drilling methodology which helps reduce noise levels and helps speed up construction in marine areas.[112]

Noise and vision barriers

The MMRDA will install noise and vision barriers on a 6 km section of the MTHL. The vision barriers are intended to block the view of the BARC from the MTHL, while the noise barriers are intended to protect the movement of flamingos and migratory birds at the Sewri mudflats. The MMRDA also stated that it would declare nearly 2 km of the MTHL on the Sewri side as a "silent zone", as well as near schools and other sensitive areas on the Navi Mumbai side of the MTHL.[113]

Metro lines

Initially, there were plans to have a dual metro line below the road lanes on the bridge. The metro Line was to be extended to the proposed Navi Mumbai International Airport and connected to the proposed Ranjanpada-Seawoods-Kharkopar corridor of the Navi Mumbai Metro and the proposed Sewri-Prabhadevi corridor of the Mumbai Metro. However, the MMRDA scrapped plans for the metro line in 2012, and decided to build only a road bridge. A senior MMRDA official stated, "A detailed study has revealed that laying the foundation for the bridge with provisions for two metro lanes would hike costs instead of save money. Hence, it will be feasible to have a separate bridge for the metro in the future." Another reason given was that the Navi Mumbai International Airport and Sewri-Prabhadevi corridor of the Mumbai Metro were still a long way from completion.[114]

Cost

The cost of the MTHL has increased several times. In 2005, the cost of the project was estimated at ₹4,000 crore (equivalent to ₹110 billion or US$1.5 billion in 2019). The cost was revised to ₹ 6000 crore in 2008. It was then increased to ₹ 8800 crore in November 2011 and to ₹ 9360 crore in August 2012.[115][116] The MMRDA re-evaluated the cost project as about ₹11,000 crore (US$1.5 billion) at 2014 prices.[117] In April 2017, the project cost was estimated at ₹17,843 crore (US$2.5 billion),[118][119] which includes ₹ 70 crore compensation to fishermen, ₹ 45 crore for installing noise barriers after opening the sea link, a ₹ 25 crore deposit as seed money to mangrove fund, another ₹ 25 crore for a compensatory mangrove restoration plan, and a mandatory expenditure of at least ₹ 335 crore for an "environment management programme".[120] In July 2017, the MMRDA announced that it would provide a one-time payment of ₹5.68 lakh (US$8,000) to each fisherman affected by the project. The agency received over 3,000 claims for compensation, and it will award payments to genuine claimants after screening the claims.[66]

JICA will fund 85% of the total cost through a loan at a concessional rate of yen-London Interbank Offered Rate plus 0.1% for the project activities, and 0.01% for consulting services, with a 30-year repayment period, including a 10-year grace period.[121][122] JICA and the MMRDA signed the agreement to disburse the first tranche of the loan on 31 March 2017. The first tranche of ₹7,910 crore (US$1.1 billion) is about 45% of the total project cost.[118][119] The MMRDA will bear 1.2% of the project cost, and the remaining amount will be borne by the State Government.[56][123] The MMRDA allocated ₹1,200 crore (US$170 million) towards the project in its budget for the 2017-18 fiscal.[124][125]

Prior to the submission of bids for the project, the MMRDA estimated the project cost at ₹14,137 crore (US$2.0 billion). The actual contract for the project was awarded to three bidders at a combined cost of ₹14,262 crore (US$2.0 billion) in November 2017.[126] MMRDA officials stated that they expected the cost to reduce by 6% as a result of the Union Government's decision to lower the goods and services tax (GST) for construction work from 18% to 12%. The revised cost of the contract would now be ₹13,400 crore (US$1.9 billion).[127]

Connectivity

The MMRDA will construct a 1.5 km long cloverleaf interchange connecting the Eastern Freeway, R.A. Kidwai Marg, Acharya Donde Marg, and the proposed elevated Sewri-Worli road, with the MTHL.[128] The loop will be built on a 27-acre plot located east of the Sewri railway station. The plot was leased for a period of 30 years from the Mumbai Port Trust. The loop consists of two lanes branching out from the MTHL and linking with the Eastern Freeway, the proposed elevated Sewri-Worli road, and the existing at-grade Messant Road. The Coastal Road intersects the proposed 4.25 km Sewri-Worli road on Worli Seaface providing additional connectivity.[129]

Eastern Freeway
Main article: Eastern Freeway (Mumbai)

The Eastern Freeway is a 16.9-kilometre-long (10.5 mi) controlled-access freeway,[130] that connects P D'Mello Road in South Mumbai to the Eastern Express Highway (EEH) at Ghatkopar.

Sewri – Worli connector

The Sewri – Worli connector would connect the Bandra-Worli Sea Link and the Mumbai Trans Harbour Link.[131] It will be a 4.5 km long cable-stayed bridge.[132]

The Sewri-Worli connector was proposed by the MMRDA in 2013 to serve as a link between the MTHL and the Bandra-Worli Sea Link. The project was estimated to cost ₹490 crore (equivalent to ₹630 crore or US$88 million in 2019), and be completed in four years.[133] The MMRDA received bids from 5 companies to construct the Worli – Sewri connector. They were Simplex Infrastructures Ltd, Larsen & Toubro, Hindustan Construction Company, Gammon India and the National Construction Company (NCC). Simplex Infrastructures Ltd quoted the lowest bid (nearly 16-17% below the estimated cost of the project), followed by Larsen & Toubro (14% below the reserve price).[133][134] In April 2016, DNA reported that the project had been cancelled, after previously being put "on hold" in 2015. No budgetary allocation was made for the project in the 2015-16 fiscal, and the MMRDA has no future plans to construct the connector.[135] The agency paused plans for the connector due to delays with the MTHL project. In 2019, the MMRDA estimated the cost of the Sewri – Worli connector to be ₹1,200 crore (US$170 million).[136]

Toll

In 2012, the MMRDA proposed tolls for the MTHL as ₹ 175 for cars, ₹ 265for light commercial vehicles, ₹ 525 for buses and trucks and ₹ 790 for multi-axle vehicles. JICA, the primary source of funding the project, proposed higher tolls in 2016.[137] The toll rates levied after the project opened was expected to be much higher due to cost escalations.[138]

The MMRDA has stated that tolls would be collected until 2045.[139]
