Motorists at Interstate 90 and Highway 52 should be alert for traffic changes beginning Monday, July 15 when construction begins at the interchange southeast of Rochester, according to the Minnesota Department of Transportation.

Motorists can expect slower speeds through the work zones and possible traffic slowdowns during peak travel times in the mornings and afternoons.

A short-term detour of Highway 52 is expected to occur July 22-26. A closure is tentatively scheduled to occur July 27-Aug. 13 from eastbound I-90 to southbound Highway 52. Once the schedules are confirmed, MnDOT will announce the detour time periods and routes in advance. Longer duration detours are scheduled in 2025 and 2026.

During the three-year, $27.5 million project, the I-90 bridges over Highway 52 will be replaced, constructing a new ramp for southbound Highway 52 to eastbound I-90, reconstructing all ramps and loops and replacing large culverts under interchange ramps.
