Construction workers this week began one of the last stages in replacing the U.S. 421 bridge connecting Milton, Ky., to Madison, Ind.
Crews moved the first 100-foot span of the new bridge from temporary piers to permanent piers Thursday, a process that took about two hours.
The rest of the half-mile-long bridge over the Ohio River is scheduled to be moved to the permanent piers later this month. Once the span is in place on the permanent piers, the bridge will remain closed while workers connect it to the permanent approaches on the Kentucky and Indiana sides of the river.
The bridge replacement project, which began in 2010, is expected to be completed later this year. Explosives were used to bring down the old bridge last year. Until the new bridge opens, the nearest river crossings are the Kennedy Bridge on Interstate 65 at Louisville (46 miles southwest) and the bridge over Markland Dam (26 miles northeast).
