A detour for westbound Highway 14 motorists who use the northbound Interstate 35 on-ramp south of Owatonna begins sometime during the week of April 16, weather permitting.

Westbound Hwy 14 motorists east of I-35 are moved into the eastbound Hwy 14 lanes, so two-way traffic will flow in the eastbound lanes. Because of this traffic change, westbound Hwy 14 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. The detour will remain in place until the two Hwy 14 bridges are reopened to traffic in the fall.

Traffic on I-35 is expected to change to in mid-April. Two-way traffic will be established in the southbound lanes, so workers can replace the bridges in the northbound lanes. The northbound Straight River Rest Area will close when traffic is switched, but the southbound Straight River Rest Area will be open for southbound traffic.

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.
