Construction Layout – Willis Avenue Bridge over Harlem River
Manhattan & Bronx, NY
NYC Dept. of Transportation
Post Construction Inspection
The Department of Transportation replaced the bridge, including the FDR Drive approach ramp and the ramp onto Bruckner Boulevard. NYCDOT also reconstructed Willis Avenue over the Major Deegan Expressway for the New York State Department of Transportation (NYSDOT).
The new bridge was constructed adjacent to and just south of the existing bridge. Thus, traffic, including the BX-15 bus, continued to use the current bridge until the new bridge opened, resulting in limited impact to motorists and nearby communities. The new swing span was fabricated and assembled off site, and was floated into place once the foundations, center pier and rest piers were ready to receive it.
Hirani provided the Baseline adjustment for both the Manhattan and Bronx side of project. Our Field Crew utilized the latest Reflector-less Total Station and RTK GPS Receiver with a TDS Data Collector to provide monitoring, Pre-Construction Lay-out and Post-construction inspection of all Roads, Caissons, Abutments, Structural Barges, Columns, Decking and other structural and support pieces, along with utilities and the ramps onto and off of the bridge itself to ensure the highest accuracy and integrity needed for such a complicated interchange connecting Manhattan to the Major Deegan, The Bruckner, and The Bronx.
