Tappan Zee Constructors (TZC) announced December 1 that it had completed installation of all road deck panels for the westbound approaches of the New NY Bridge.
TZC placed nearly 3,000 steel-reinforced concrete panels, weighing as much as 74,000 pounds each, atop the westbound steel girder assemblies to create the base driving surface of the bridge. Deck panel installation continues on the eastbound Rockland approach, as well as both cable-stayed main spans.
The $3.98 billion project remains on track to be completed in 2018, according to New York State Thruway Authority and TZC officials.
Construction of the new three-mile span began in 2013. The state-of-the-art structure will include eight traffic lanes and four breakdown and emergency lanes. It is designed to handle “extreme” loadings and blastings and have an anticipated service life of 100 years. The current Tappan Zee was built in 1955 and was designed to last 50 years. It will be dismantled by the end of 2018.
