Steele County and the City of Owatonna are undertaking a pavement rehabilitation project along two important routes through Owatonna:
- CSAH 45 (Oak Avenue) from Rose Street to Holly Street, and
- CSAH 19 (Rose Street) from Hoffman Drive to Willow Avenue.
Staff from Steele County, City of Owatonna, and their consultant team from SRF Consulting Group have been studying the project corridors to identify pedestrian and vehicle safety and operations improvements. The first phase of construction was completed in the fall of 2018 and addressed the uneven pavement along CSAH 45 (Oak Avenue) between School Street and McKinley Street.
The next phase of improvements is scheduled for construction in 2019 and will include:
- The conversion of CSAH 45 (Oak Avenue) from a 4-lane road to a 3-lane road.
- Adding a mini-roundabout at CSAH 19 (Rose Street) & Grove Ave.
- Traffic signal modifications including the removal of two existing signals on CSAH 45 (Oak Avenue at Vine Street and McKinley Street.
- Pedestrian crossing enhancements at CSAH 45 (Oak Avenue) and School Street.
Construction Dates: Summer 2019
Traffic Impacts: To be determined.
More Information: A public information meeting was held January 10, 2019.

Four-lane to 3-lane road conversions
Our neighbor in Iowa, the Iowa Department of Transportation, has produced a great video explaining converting an existing four lane road with two through lanes in each direction to a three lane road with one lane in each direction and a center turn lane. This is similiar to the work Steele County is proposing for Oak Avenue. Click here to learn more.
