This historic structure features a 533m-long main suspended span and is almost 2.9km long in total.
The consultant will perform a close visual hands-on inspection of the bridge to update the condition of all fracture-critical members and fatigue-sensitive evaluations. Modjeski & Masters will also write a bridge-specific load rating manual for the bridge, as well as perform a subsequent load rating on the bridge according to that manual.
“This project and the bridge in general is particularly special to our firm. Back in the 1920s, our founder, Ralph Modjeski, led the original design and construction effort, and we’re proud to continue his work on the Benjamin Franklin Bridge," said Mike Britt, president and CEO of Modjeski & Masters.
The bridge inspections will start later this month and the final report is due to be delivered to DRPA in December.
