Milton-Madison Bridge: The Largest Bridge Slide in North America
The recent completion of the Milton-Madison Bridge over the Ohio River as a design/build project represents several precedent setting innovations including deep reinforcement of existing unreinforced concrete caissons and a project procurement process which promotes innovation. The most significant innovation was the lateral sliding of the bridge. This allowed the bridge to be replaced on its current alignment while only requiring a few weeks of closure instead of the originally planned year or more of closure with a ferry service.
This presentation will focus on the details of how the bridge slide was accomplished. A 2,400-foot-long continuous new truss was constructed beside the existing truss, supported on temporary piers, and then slid on to rehabilitated existing piers, representing the largest bridge in North America that has utilized this method. Additionally, a girder type approach span was slid, and while on a much smaller scale, offered its own set of design and construction challenges.
Watch a time lapse video of the historic bridge slide.
B&N’s Tom Bolte, PE will co-present this session with Murray Johnson from project partnering firm Buckland & Taylor.
