If weather cooperates, Highway 169 north of St. Peter could reopen to traffic and the detour removed as early as Thursday. Drivers would still be restricted to two-way traffic along the highway’s northbound lanes once the detour ends as southbound construction and resurfacing is completed. The three-week detour is part of a $10.7 million project that will raise the southbound lane several feet along a two-mile flood prone area between St. Peter and Le Sueur. This is the first of a three-part project MnDOT has planned to protect Highway 169 against a 100-year flood. Part two of the project will be done in 2015 and part three in 2016.
