Harlem River Drive Ramp to RFK Bridge

New York City<br style='line-height:2px'>MTA Bridges & Tunnels

HAKS partnered with the general contractor for the $9 million design-build reconstruction of the Harlem River Drive southbound ramp to the Robert F. Kennedy Bridge to correct severe deterioration of the original ramp’s concrete deck. This was the first transportation infrastructure design-build project for MTA Bridges & Tunnels and the design-build team.

The project required a complete superstructure replacement of the 11-span, 460-foot-long curved ramp structure leading to the bridge, reconstruction of the 320-foot-long approach roadway, and expansion of the ramp width from 20 to 24 feet, creating a wider driving surface and the potential for two travel lanes. A detour to the RFK Bridge from the southbound Harlem River Drive via city streets was also constructed.

As the team’s engineering consultant, HAKS was responsible for designing various components of the structure, including structural steel stringers and floor beams, bolted connections, elastomeric bridge bearings, pedestals, a reinforced concrete bridge deck, armorless bridge joints, modified abutment backwall and wingwalls, drainage scuppers, and roadway lighting.

A strong focus on constructability accelerated design toward a seamless integration with construction without compromising the quality of the designs. Galvanized structural steel and stainless steel reinforcement were used, which will require less maintenance and become more economical over time.

The project was completed on December 19, 2011 in less than 6 months, and 4 days ahead of schedule, earning an incentive bonus. It received the 2013 ACEC-New York Platinum Award for Engineering Excellence.
