Additional Info.
High Steel is in the first stages of steel fabrication for the $103-million Milton-Madison (U.S. 421) Bridge Project, a bi-state effort between The Indiana Department of Transportation and the Kentucky Transportation Cabinet. The new truss bridge will replace an 81-year old deteriorating bridge spanning the Ohio River between Milton, KY and Madison, IN.
High Steel is contracted to provide 8,165 tons of structural steel for the complex 3,181-foot design-build truss project. General contractor Walsh Construction will construct the new steel superstructure on temporary piers immediately downstream of the existing bridge, and the new truss will be put in place using a controlled slide along steel rails to its permanent location on the renovated existing piers, which will be widened and rehabilitated before the move. This innovative erection plan reduces the project's cost and limits construction-related bridge closures to just 10 days, as opposed to a full year using traditional methods. The new bridge is scheduled to be open to traffic in Fall 2012.
