The I Lift NY crane places a 750,000 pound section of structural steel to connect the Rockland Approach to the Main Span. This work in early February of 2017 was the first connection between the cable-stayed Main Span and any of the pier supported approaches.

To handle the job, Fort Miller hired additional staff and added a 12,000-square-foot facility featuring two overhead cranes. Similar advantages were enjoyed by the subcontractors who assembled the massive girder sections on-shore at the Port of Coeymans facility—a sixteen-acre riverfront site in Albany county. Assemblies with multiple girder—each several hundred feet long, with many weighing more than 700 tons—had a variety of mechanical and electrical components installed before being shipped down for installation, boosting safety and efficiency.

I Lift NY Puts Pieces in Place After months of work to modify and update a variety of systems, including replacement of its rigging cables, Te I Lift NY super crane completed its first lift on April 24, 2015. In an operation requiring more than three hours, it lifted and placed a 600-ton precast pile cap. Tose components link the underlying piles into a support structure for piers and towers above. Numerous pile and pier caps would follow before the bridge would really begin to assume its shape—rendered in structural steel. In June of 2015, the super lifter placed the first


steel girder assembly in a lift totaling up at 1,360 tons including the rigging and lifting frame. Te lifting frame is engineered with hydraulic systems to adjust the load and allow precise placement of this 410-foot-long assembly and 133 others to eventually be incorporated into the project. Placement of steel continued into 2016, and in the early spring, extensive preparation and favorable weather combined to allow the teams to install about 1,400 feet of girder structures in a little more than one week. A major milestone came to pass in the first week of October 2016, when the final girder assembly of the Westbound span was placed—less than a year before it would be handling traffic.
