Overnight Interstate 90 Closure Planned at Exit 332 in Mitchell for High-Mast Tower Removal

MITCHELL, S.D. - Beginning at 8 p.m. on Wednesday, Nov. 11, 2026, eastbound and westbound traffic on Interstate 90 will be closed until 6 a.m. Thursday, Nov. 12, 2026, for the removal of high-mast light towers. During the closure, I-90 traffic will be routed through the on- and off-ramps to maintain traffic flow. S.D. Highway 37 traffic underneath the overpass will be reduced to a single lane in both the northbound and southbound directions and guided through the intersection by flaggers to maintain traffic flow.

The work is part of a project that includes the installation of new interchange lighting at exits 330 and 332. The project also includes new luminaire lighting along the eastbound and westbound on- and off-ramps at both exits.

The primary contractor for this $2.2 million project is BX Civil and Construction of Dell Rapids, SD.
