Eastbound Highway 14 motorists south of Owatonna will experience a two-day traffic detour during the daytime hours Aug. 8-9 for construction crews to repair the slope beyond the road that stabilizes and supports the road embankment.

Crews will be using the eastbound Highway 14 lane through the current bridge replacement construction zone to assist with the repairs from 7 a.m. to 7 p.m. Aug. 8 and Aug. 9. Westbound Highway 14 traffic will not be detoured.

The detour affects eastbound Highway 14 between Interstate 35 and Steele County Road 45. The detour route for eastbound Highway 14 is to proceed northbound on Interstate 35 to exit 41 Bridge Street in Owatonna. Turn right on Bridge Street. Follow Bridge Street through town. The road turns into Main Street at the intersection of Oak Avenue. Continue on Main Street, which will turn into Bixby Road and take motorists to the interchange at Highway 14 and Highway 218 southeast of Owatonna.



Motorists on Interstate 35 south of Owatonna will travel in single lanes in each direction in the southbound lanes during the project.

Traffic delays are expected on Friday afternoons and evenings and Sunday afternoons.

Hwy 14 westbound motorists who want to travel north on I-35 will need to detour through the interchange loops at I-35 by taking the southbound I-35 ramp to the eastbound Hwy 14 ramp to the northbound I-35 ramp.

Motorists who use Steele County Road 18 to cross I-35 are reminded that the road is closed at the bridge. It is one of the bridges being replaced. They may detour around the crossing by using Hwy 14.

This bridge replacement project is in its second of two years south of Owatonna. Twelve bridges are being replaced over two years on I-35 (eight bridges) and Hwy 14 (four bridges). Bridges on southbound I-35 and eastbound Hwy 14 were replaced last year. Two bridges on I-35 that were damaged by a vehicle crash last year are included in the project. One was replaced last fall and the second is under construction this year.
