The Willis Avenue Bridge spans the Harlem River between Manhattan and the Bronx. NYCDOT undertook a project to replace the historic moveable swing bridge with a new swing bridge to improve lane width and to address structural deficiencies. The project also included new approach viaducts and ramps.
PHA provided engineering and environmental planning services as a subconsultant to Hardesty & Hanover. PHA prepared the NEPA Environmental Impact Statement (EIS) and the Uniform Land Use Review Procedure (ULURP) application and drawings, and coordinated the public review process. Potential impacts to cultural resources were a key concern as the 100-year-old bridge was eligible for inclusion on the National Register of Historic Places. The project required street mapping in both Manhattan and the Bronx to accommodate the new alignment. PHA was responsible for the civil design of all at-grade work. This included preparing the maintenance and protection of traffic (MPT) plans and construction staging for the multiphase construction schedule. As part of its construction support services, PHA monitored implementation of the MPT and developed adjustments as needed.
