The new Milton-Madison Bridge’s record-breaking 55-foot journey from temporary piers to permanent, refurbished piers was completed April 10, 2014. Spanning nearly a half mile, the truss of the Milton-Madison Bridge is now the longest bridge in North America — and perhaps the world — to be slid laterally into place.

The slide began Wednesday morning, April 9, but was halted in the late afternoon because of high winds over the Ohio River. Walsh Construction, which is building the Milton-Madison Bridge, brought in materials from the Louisville-Southern Indiana Ohio River Bridges Project to help deal with windy conditions and assist in synchronizing the slide onto the bridge’s five piers. This allowed the slide to resume the next morning.

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. The original Milton-Madison Bridge opened in 1929.

The Milton-Madison Bridge Project is a joint effort between the Indiana Department of Transportation and the Kentucky Transportation Cabinet.
