The new RFK Bridge Ramp remains elevated above the roadway median as it passes over ramps to the Willis Avenue Bridge and then ties in with the recently constructed Harlem River Drive Viaduct. The new ramp will divert traffic away from city streets, calming traffic at the entrance to a future waterfront park, reducing noise and improving air quality. Further, vehicles passing over the RFK Triborough Bridge can reach their destination more quickly, making this project a win-win for the whole area.
In addition to designing many interfacing projects in the area, H&H has been involved in the design of the new ramp since its inception. TBTA retained H&H to evaluate various alignment alternates for a one-way passenger vehicle ramp, which is anticipated to carry an ADT over 19,000 vehicles per day. The study identified the most prudent and feasible alternative to directly connecting the RFK Bridge to northbound Harlem River Drive.
Post-study, H&H designed the stub out ramp connection at the RFK Bridge, which was built under ongoing project RK-23A, and designed modifications to the Harlem River Drive HBM-1027 project, which was also under construction by NYCDOT. Foundations for the new RFK ramp were designed by H&H and built by the NYCDOT project contractor.
Following, H&H prepared the indicative and directive plans for the ongoing design-build contract and continues to be involved in the project by providing Design Quality Assurance for TBTA under an Authority-Wide As-Needed Engineering Services contract.
