Prospect - Gowanus Expressway Reconstruction
Brooklyn, NY

DESCRIPTION:
This project required the complete reconstruction of the Prospect-Gowanus Expressway Interchange, the first since the artery was originally completed in 1964. Included was the widening of the Inbound Gowanus Expressway from 4th Avenue to the Gowanus Canal. The first Brooklyn-Staten Island HOV lane was constructed as part of this project and is still in operation today. The project was completed ahead of schedule with minimal impact to the surrounding community.

SCOPE:
This project required the construction of new pile foundations along Hamilton Avenue to support the new box columns that would be used for the roadway widening; new abutments and piers were constructed at 3rd Avenue. Both, the 4th Avenue and 3rd Avenue bridges along with the right lane of the Expressway were completely removed and replaced with new structural steel and cast-in-place concrete decks. Deteriorated pavement on the Prospect Expressway was replaced by new cast-in-place concrete. Painting, drainage and signage were upgraded while landscaping was performed and community playgrounds were improved.

NOTEWORTHY:
This $81 Million project was completed ahead of schedule
