Left Coast Lifter

After Left Coast Lifter arrived at the Bay Area in March 2009,[6] it was used to place pre-fabricated falsework truss sections and the 28 box girder deck sections.[7][8] Before the heavy deck sections for the Bay Bridge were lifted, Left Coast Lifter raised a sunken tugboat in August 2009, USS Wenonah.[9] The first deck section was lifted in February 2010,[10] and the last deck section was lifted in October 2011.[11]

American Bridge/Fluor solicited offers for Left Coast Lifter in 2012, after the conclusion of its work on the Bay Bridge.[12] A consortium of companies, Tappan Zee Constructors (TZC, a joint venture of Fluor, American Bridge, Granite and Traylor Brothers), purchased the crane barge, which gave them a competitive edge in the bidding process for the construction of the Tappan Zee Bridge replacement across the Hudson River.[13] Reportedly, according to the purchase agreement between TZC and ABFJV, Left Coast Lifter will be returned to ABFJV once the work on the Tappan Zee Bridge is completed.[14][15]

Now nicknamed I Lift NY, the barge is still officially registered with the U.S. Coast Guard as Left Coast Lifter. The crane departed San Francisco Bay under tow in December 2013, transited the Panama Canal in January 2014,[16] and arrived at Jersey City at the end of January.[17] There it was refitted with an upgraded control system[18] before arriving at the job site in October 2014.[19] Left Coast Lifter made its first lift on the new Tappan Zee bridge in April 2015,[20] a steel-reinforced concrete pile cap which formed part of the bridge's foundation.

The massive crane was being used for heavy lifts of large bridge sections,[21] and placed the final steel girder for the new Rockland-bound (westbound) span in October 2016.[22] The final lift for the eastbound span to Westchester was completed in April 2018.[23] Between and after the assembly of the new bridge spans, Lifter was also used for heavy lifts during the dismantling of the original Tappan Zee Bridge at that location.[24][25]

The eastern span of the old Tappan Zee Bridge was dropped into the Hudson via controlled detonation in January 2019; although the intent was to dismantle the bridge in place, during opening celebrations for the replacement Mario M. Cuomo Bridge in September 2018, a loud pop was heard and the original Tappan Zee bridge was closed to workers, as engineers determined it had become unstable. The Federal Highway Administration approved a revised plan to detonate the original bridge's supports in December 2018.[26] "I Lift NY" was used to retrieve portions of the old bridge from the Hudson;[27] in October 2019, the crane left the Hudson and was stored on Staten Island,[28][29][30] at Caddell Dry Dock and Repair Co., Inc.[31][32]

Left Coast Lifter was also used for a heavy lift during the summer 2018 maintenance of the Spuyten Duyvil Bridge; the crane moved the swing section of the bridge onto a barge in June to facilitate work on electrical and mechanical equipment that had been damaged during Hurricane Sandy.[33] The bridge was returned in August, once refurbishment was complete.[34]
