Best Highway/Bridge: Delaware Memorial Bridge UHPC Pilot Project
The twin spans of the Delaware Memorial Bridge were showing their age by 2018, with more than 1 billion cars and trucks having rolled across their decks over the decades. Built in 1952, the deck of the older of the two spans was judged to be approaching the end of its service life.
Working with WSP USA, the Delaware River and Bay Authority opted for a new and cutting-edge approach to replacing the deck with the use of ultra-high performance concrete, or UHPC.
