The four assemblies will be placed on two piers near the Rockland landing. The operation is unlike previous assembly efforts, utilizing both the I Lift NY super crane and floating barges to place the structural steel atop the bridge’s concrete piers.

The assemblies are large sections of structural steel, composed of 12-foot-tall girders that weigh about 60 tons apiece. 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 and then floated by barge directly to the project site for installation.

TZC will install 10 additional steel girder assemblies on the eastbound span in future operations, scheduled to begin later this year.
