Resident Engineering Inspection - Reconstruction of Willis Avenue Bridge over the Harlem River, Boroughs of Manhattan and Bronx, NY

This $612M NYCDOT project involves the replacement of the Willis Avenue Bridge, a swing-type movable bridge over the Harlem River along with approach roadways and spans in Manhattan and the Bronx. The new bridge is being constructed just south of the existing bridge. The work in Manhattan involves construction of a temporary loop ramp to direct 2 lanes of traffi c from NB FDR to the Bridge in order to remove the existing and construct the new ramp. The approach from 1st Ave is done in stages to maintain 2 lanes of traffi c at all times. Most of the work in Manhattan requires extensive MPT for the demolition and all the construction work over, in the median or adjacent to FDR/HRD. Work in the river involves construction of new piers founded in bed rock with close coordination with USCG to maintain the navigation traffi c without impact. The new swing span along with all machinery and electrical system is fabricated and assembled off-site and fl oated into center pier, and rest pipes. In the Bronx work involved construction of spans over the Harlem River Yard, Waste Management Facility, CSX Rail Road and Bruckner Boulevard as well as a new exit ramp in to Bruckner Boulevard. A NYSDOT Project for the replacement of the Willis Avenue Bridge over Major Deegan Expressway (MDE), construction of fl yover ramp to NB MDE and reconstruction of the MDE in the vicinity of the bridge along with entrance and exit ramp are also done under the same contract.
