Progress continues on the installation of American-forged steel girders, which link the concrete piers across the Hudson River and provide support for the road deck. Tappan Zee Constructors, LLC (TZC) recently began installing a key section of girders that connect the Rockland landing to nearly 3,000 feet of already-installed girders in the river.
TZC is using a land-based crane to install the girders near the Rockland shoreline, implementing periodic traffic changes on River Road to enable efficient and safe installation. Unlike the structural steel near the Westchester landing – which are grouped into massive assemblies of multiple girders before installation – the Rockland girders will be placed individually and bolted together once in place. The effort is anticipated to wrap up prior to Thanksgiving, thereby keeping the road clear for holiday travelers.
As this new section of girders progresses, the I Lift NY super crane is methodically continuing its mission of lifting girders onto piers across the entire river, averaging two placements a week. A total of 31 miles of steel girders cumulatively weighing more than 100,000 tons will be installed for the new twin-span bridge.
