Woodrow Wilson Bridge

  • Haunched Girder


The Woodrow Wilson Bridge carries the Outer and Inner Loop of Interstates 95 and 495 over the Potomac River in the Washington, D.C. metropolitan area.

After initial bids for the Woodrow Wilson Bridge exceeded its budget in 2001, the bridge's haunched parabolic tub girder design was changed to a more economical haunched plate girder design.  This allowed the designers to keep the aesthetics of the original design while lowering fabrication and shipping costs. The bridge project was also split into three contracts.

Contract BR-3C was advertised in January 2003. High Steel was awarded the 20,900-ton fabrication contract for the 19-span steel superstructure for the Maryland side of the bridge.

The project included detailing and fabricating over 700 girders and the associated stringers, diaphragms, plate diaphragms, and miscellaneous parts. The last steel deliveries were completed in May 2007, and the overall project was completed in 2009.
