Milton-Madison Bridge
PROJECT OVERVIEW
Updated River Crossing Retains Historic Character
High Steel fabricated structural steel for the $103-million Milton-Madison Bridge Project, a bi-state effort between The Indiana Department of Transportation and the Kentucky Transportation Cabinet. The design of the new truss bridge echoes the 81-year-old bridge it replaced, which spans the Ohio River between Milton, Kentucky, and Madison, Indiana.
High Steel supplied 8,165 tons of structural steel for the complex 3,181-foot design-build truss project. General contractor Walsh Construction constructed the new steel superstructure on temporary piers immediately downstream from the existing bridge. The new truss was put in place using a controlled slide along steel rails to its permanent location on the renovated existing piers, which were widened and rehabilitated before the move. This innovative erection plan reduced the project's cost and limited construction-related bridge closures to just 10 days. The new bridge first opened to traffic in its permanent location in 2014.
