Kwun Tong Bypass

The eastern terminus of the Kwun Tong Bypass is located above the junction of Lei Yue Mun Road and Tseung Kwan O Road, which connect to the Eastern Harbour Crossing and Tseung Kwan O Tunnel, respectively. The point where the bypass nearly meets the Tseung Kwan O Road (immediately south of the Kwun Tong Magistracy) was originally slated to be the site of a cultural centre for Kwun Tong. Instead, the bypass and an electric substation were built on the site and Kwun Tong still has no cultural centre.[1]

The bypass travels southwestward in the form of viaducts above Wai Fat Road (between Kwun Tong Business Area and Laguna City) until the interchange with Wai Yip Street, where it bends northwestwards to run along the waterfront frontage of Kwun Tong Business Area southwest of Hoi Bun Road (lit. seashore road). Formerly a cargo working area, the strip of seaside land beneath the elevated road has been developed into the Kwun Tong Promenade in recent years.

Approaching the entrance of Kai Tak Tunnel at Kowloon Bay, the bypass continues to be elevated atop Kai Fuk Road (part of Route 5. Kai Fuk Road acts as the connection between Kwun Tong Road, Kwun Tong Bypass and Kai Tak Tunnel. Ramps are available near KITEC and MegaBox for vehicles to switch from the elevated Kwun Tong Bypass westbound to Kai Fuk Road westbound on the ground level, and from Kai Fuk Road eastbound to Bypass eastbound, to enter/exit Kai Tak Tunnel.

The bypass viaduct deviates from Kai Fuk Road and turn due north outside KITEC, just east of Kai Tak Tunnel portal. From here the bypass traverses the eastern perimeter of the former Kai Tak Airport apron, which has been redeveloped into public housing (Tak Long Estate) under the Kai Tak Development scheme. The section of viaduct outside Richland Gardens has been enclosed by noise barriers to mitigate the impact of traffic noise to residents there.

At the northwestern corner of Richland Gardens the bypass continues northwards as the approach road to Tate's Cairn Tunnel. The name "Kwun Tong By-pass" is not officially applied to the section of viaduct between Richland Gardens and Tate's Cairn Tunnel southern portal, which is considered part of Tate's Cairn Tunnel and falls within the jurisdiction of Tate's Cairn Tunnel Ordinance. Nevertheless, many motorists erroneously regard that portion of viaduct as part of Kwun Tong Bypass.

Kwun Tong Bypass in its entirety has been designated an expressway under the Road Traffic Ordinance (Cap. 374, Laws of Hong Kong).[2] Speed limit at the two ends are 70 km/h while the section in the middle (between KITEC and Kwun Tong Ferry Pier) is 80 km/h.

The road network of the East Kowloon area was at the brink of being overwhelmed at the turn of the 1990s. Within three years three road tunnels, namely Eastern Harbour Crossing (1989), Tseung Kwan O Tunnel (1990) and Tate's Cairn Tunnel (1991) would open, each putting extra pressures to the existing road system of Kwun Tong. According to a government estimate, the traffic volume in the area would see a sixfold rise upon the opening of the three tunnels.[3] It would be unrealistic to route all through traffic to Kwun Tong Road and Wai Yip Street, the two east-west arteries that penetrates through Kwun Tong District.

The idea of constructing an expressway bypassing Kwun Tong town was conceived in 1985 by New Hong Kong Tunnel Company Limited, the build–operate–transfer (BOT) franchisee for the Eastern Harbour Crossing (EHC) project. Such a bypass was not only seen as the antidote to congestion in East Kowloon, but also a solution to the increasing traffic volume generated by the industrial development in Kowloon Bay Industrial Area. The government approved the proposal of constructing Kwun Tong Bypass and works started in August 1987.

Phase 1 of the Kwun Tong Bypass spans from the junction of Lei Yue Mun Road and Tseung Kwan O Road to Wai Yip Street. New Hong Kong Tunnel Company Limited was given the responsibility to undertake its construction on behalf of the government, as it was considered part of the associated works of the EHC project. Construction of this section was completed by Kumagai Gumi in September 1989, when it was opened to traffic together with the Harbour Crossing.

The HK$782 million contract—Highways Department's largest engineering contract since its formation—for the construction of Kwun Tong Bypass Phase 2 was awarded to the Dragages–Bachy Soletanche joint venture. Works on this 2.3-kilometre (1.4 mi) section, which connects Wai Yip Street to Kai Fuk Road near the eastern portal of the Airport Tunnel (now renamed Kai Tak Tunnel), began in April 1988. The novel construction method of using precast concrete slabs resulted in the early completion of works by one month. It was opened by Kwei See Kan, the Director of Highways, on 14 June 1991.[4]

The final section of the bypass, which extends northwards from Kai Fuk Road and connects with the approach to Tate's Cairn Tunnel, was commissioned on 26 June 1991 together with the tunnel, 12 days after the opening of Phase 2.

The entire Kwun Tong Bypass falls within the boundaries of Kwun Tong District.
