Woodrow Wilson Bridge

Washington DC

Project Description

Located in Washington, DC, the Woodrow Wilson Memorial Bridge is a 6,000-foot long replacement for the existing structure which carries Interstate I-95 / I-495 over the Potomac River.

The twin replacement structures feature deck widths of up to 148 feet utilizing a unique structural system that mimics the arch bridge at other points along the Potomac River.

The concrete v-shaped piers were designed to be built using the precast segmental method. There are four steel girders which sit atop each V-Pier and support a reinforced concrete deck. The 175-foot navigation channel is spanned with an eight-leaf double bascule structure.
