New York City Department of Transportation (NYC DOT) officials have said they soon will release a request for proposals (RFP) for a project that will rehabilitate the 62-year-old triple cantilever that underpins the Brooklyn Heights Promenade along the Brooklyn-Queens Expressway (BQE). The project is expected to take five years to plan, another five years for construction and cost the NYC DOT $1.7 billion. Included in the project will be 21 bridges and other structures, which will improve roadway and ramp configurations. The RFP will be issued in May, and the design phase will begin in early 2017 and be completed in 2019.
Construction could start in 2021 and is scheduled to be completed by 2026. The highway’s triple cantilever design in Brooklyn Heights includes two levels for BQE traffic and another for the Promenade, with a city street running beneath it all. The expressway sees an average daily traffic of more than 140,000 vehicles.
