T.Y. Lin International (TYLI) provided value engineering design for the superstructure replacement and substructure rehabilitation of the twin-span New York Avenue Bridge in Washington, DC. The bridge, which originally opened in 1966, is a major transportation corridor into Washington, DC from the state of Maryland.

The design-build project included the demolition, removal, lowering, and reconstruction of the twin-span bridge superstructure, using accelerated construction techniques, as well as the rehabilitation of piers, widening of existing abutments, construction of two independent piers to support two gateway monuments, and overall improvements to the approach roadways, pedestrian sidewalks, and roadway lighting features.

With concurrent improvement projects taking place on other roads, the primary goal for project owner, the District Department of Transportation, was limiting traffic impacts on the already-congested New York Avenue corridor. The bridge also crosses numerous rail lines operated by Amtrak, Metrorail, and regional commuter trains, which made it imperative to limit traffic impacts when addressing constructability issues.

Project Highlights:

  • The use of precast, post-tensioned concrete deck panels that cantilever over the exterior girders allowed for faster construction, eliminated delays associated with formwork construction and concrete curing time, facilitated deck replacement, and caused less disruption to railway traffic.
  • Construction included the removal of the existing bridge deck, barriers, lighting, girders, beams, bracing, piers and bearings; new beam seats backwall, as well as pier columns and post-tensioned cap beams; reinforced concrete deck and joints at each abutment; and the design, installation, and removal of temporary structures for construction personnel working over high-voltage wires and rail tracks.
  • Pavement restoration was performed on New York Avenue to match the elevation change of the bridge abutments.
