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.
