Delaware Memorial Bridge


Delaware Memorial Bridge

The twin steel suspension bridges carry eight lanes of Interstate 295 and U.S. Route 40 traffic between Delaware and New Jersey. HTNB teamed up with engineer Othmar Ammann to design the bridges, which are dedicated to local soldiers who died in World War II, the Korean War, the Vietnam War, and the Persian Gulf War.

When the first span opened, it was the sixth-longest main suspension span in the world. When the second span opened in 1968, the Delaware Memorial Bridge became the world's second-longest twin suspension bridge.

The Delaware Memorial Bridge won an NSBA Prize Bridge Award in 1951.
