While this project required more lane closures than previous repair efforts, Delaware River and Bay Authority executive director Tom Cook said the replacement project was long overdue. The last comprehensive re-decking dates back to 1969.
“This is the conclusion of a multi-year, $71 million dollar project to reject the northbound span of the Delaware Memorial Bridge. It’s on budget, and ahead of schedule,” said Cook. “The most comprehensive deck overlay in the span’s 72-year history and as we are making history today also as this is the largest application of the ultra-high-performance concrete in the whole United States.”
A multimillion dollar project is underway at the Delaware Memorial Bridge to enhance its protection system and prevent future collisions like the 1968 tanker.

The project is part of the ongoing effort to keep the decades-old twin spans in good condition. The New Jersey-bound bridge opened in 1951, and the Delaware-bound bridge opened in 1968. Some 18 million vehicles cross the bridge every year on average.
“With every construction project, our goal is to complete the necessary work safely while making sure traffic impacts to our customers are kept to a minimum. We want to thank our customers for their patience and understanding during all three phases of this reconstruction work on the bridge desk,” he said.
The project is unique for its use of ultra-high-performance concrete.
“This is the first time that this material was used on a major bridge in the United States,” said Gilbert Brindley, director for UHPC Solutions North America. “It’s two inches thick, it’s the largest application of UHPC ever at nearly 5,000 cubic yards of material.”
Now that the project is complete, all eight traffic lanes across the river will be open to traffic starting on Tuesday, November 21 at 6 a.m.
