Milton-Madison Bridge Slide

Time-lapse Video of Milton-Madison Bridge’s 55-foot slide from temporary piers to its permanent, refurbished piers.

The deteriorating 84-year-old Milton-Madison Bridge, carries US 421 across the Ohio River connecting the historic towns of Madison, Ind., and Milton, Ky. Using a construction method called “truss sliding,” a new 2,427-foot-long truss will be moved along steel rails and plates and “slide” into place atop the existing piers, which will be rehabilitated. So, on April 10, the new bridge’s 55-foot journey from temporary piers to its permanent, refurbished piers came to a successful completion. The slide – the longest bridge slide in North America – moved the 2,428-foot steel truss bridge onto its refurbished piers 55 feet to the east of the temporary piers. Polished steel sliding plates were secured on top of the refurbished piers. Steel cables and eight computer-controlled hydraulic jacks were used to pull the bridge through a series of grabs and pulls until the bridge was slid into place. The 30-million pound new steel truss bridge is 2,428-feet long and 40-feet wide with two 12-foot lanes and 8-foot shoulders – twice as wide as the old bridge. A 5-foot-wide cantilevered sidewalk will be added to the structure in the coming months.
