FDR Drive 48th Street On-Ramp Manhattan, NY

DESCRIPTION:
This project required the complete demolition and replacement of the decaying 48th Street On-Ramp to the FDR Drive. The need to maintain traffic for the high-security United Nations entrance gate located within the footprint of the project and building the ramp directly above the continuously active FDR Drive presented a multifaceted scenario that DeFoe Corp. was able to conquer 4 months ahead of schedule.

The new ramp was a complete redesign incorporating new piers, abutments, structural steel and a cast-in-place concrete deck. The innovative design included curved steel and trapezoidal girders that provided smooth flowing lines and an architectural finish appropriate to its surroundings.

SCOPE:
This project required the complete demolition of the structural steel and concrete deck. Most challenging were the fabrication and subsequent erection of the curved steel and trapezoidal girders. Cast-in-place concrete decks with integrated concrete barrier provided the final roadway surface, while a community friendly landscaping layout and an adjacent park and playground improvements completed the project.
