As the new Tappan Zee Bridge continues to advance towards completion, workers have been busy installing concrete noise barrier panels along the New York State Thruway in South Nyack with the goal of having the structures complete in April.
The barriers are treated with a sound-absorbing material to further reduce traffic noise in the nearby community.
In addition to the sound barriers, construction crews also plan to continue the girder assembly installation next week on the eastbound bridge, placing three assemblies on two piers near the Rockland landing with the project’s largest crane, dubbed I Lift NY.
The assemblies are large sections of structural steel, composed of 12-foot-tall girders. They also include infrastructure to carry communications, electrical power, water and compressed air to support bridge operations.
Each section is arranged at the project’s Port of Coeymans facility in Albany County and barged directly to the project site for installation.
TZC will also install the final section of westbound structural steel in the coming days, weather permitting. The operation will occur near the center of the 2,230-foot-long main span and connect the westbound bridge from Westchester to Rockland counties.
Other ongoing projects include the installation of the overhead gantries or sign structures. TZC will outfit the gantries with variable lane use and electronic message signs, as well as traditional exit signs. As well as continuing to install fencing along the barriers of the new bridge.
