West 125th Street Construction Management for Streetscape Improvements

The W125th Street Streetscape Improvement project is one of three-stage strategic projects implemented by the NYCEDC to revitalize West Harlem. The master plan was developed in 2002

  • Waterfront Amenity;
  • Transportation Improvement and
  • Economic and Institutional Improvement.  

W125th Streetscape and Intermodal Improvements project is the second stage and will complement and improve the neighborhood's connection to WHPP, enhance the area's streetscape for the benefit and safety of pedestrians, and strengthen the connections among the different transportation modes present in the area.


The project, with a construction value of $14.5 million, involves streetscape improvements on 125th Street, extending between the Harlem Piers to the west, and Old Broadway to the east, as well as portions of adjacent streets (see attached plan).  This area of Harlem is a vibrant community and dynamic business district with a history rich in American entertainment and culture. The existing watermain and drainage utilities will be upgraded to handle the increased load created by the ongoing redevelopment of the area.

Urban Value-Added

The West 125th Street Streetscape Improvements Project required a replacement of an existing 36” trunk main to a large 48” trunk main at a very busy intersection in New York City and under the MTA railroad bridge.  Additional measures were required such as an augmented excavation support system to maintain the integrity of the bridge structure during construction. This work required significant coordination with multiple agencies such as NYCDOT OCMC, NYCDOT Buses, NYCDEP, MTA, and multiple ongoing construction jobs in the area.  The art of communication has to be finessed to get the approval of all stakeholders and balanced with work progress.  Urban has been acknowledged for its patience and courage to resolve issues in sometimes hostile environment.
