New York Avenue Bridge Rehabilitation

New York Avenue Bridge Rehabilitation

NY Ave Bridge

TYLin provided value engineering design for the superstructure replacement and substructure rehabilitation of the New York Avenue Bridge in Washington, DC.

Originally opened in 1966, the New York Avenue Bridge 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 Bridge Construction techniques. Project scope also comprised 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.

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.

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.  

Project Highlights: 

  • Since the bridge crosses numerous rail lines operated by Amtrak, Metrorail, and regional commuter trains, it was imperative to limit traffic impacts when addressing constructability issues. 
  • Construction included removing the existing bridge deck, barriers, lighting, girders, beams, bracing, piers, and bearings. 
  • TYLin oversaw 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.
