City of Owatonna Engineering
Construction has begun and various projects can be seen around The City of Owatonna. Please slow down and use caution when approaching a construction zone. We thank you for your patience as these projects are completed. 2021 Construction Projects:2021 Project Location Map
2021 Bridge Street: Work this week was primarily focused on Phase 1A has progressed with preparation of the road base. A couple areas of soft material were encountered and were corrected to ensure a sturdy, consistent base for pavement to be placed on top of. Electrical conduit has been placed to facilitate the new signal system installation at the Bridge St. Park Dr. intersection. Phase 1A is expected to be complete within 30 calendar days from the start of the phase which results in an expected intermediate completion date of August 5th, 2021. Construction on Phase 1B began this week on July 14th with removals and subgrade preparation which required the closure of the southbound I-35 ramps at W. Bridge Street. Due to the significant traffic impacts, the work in this area is required to be expedited and completed within 10 calendar days and is planned to be re-opened on July 24th. Work within this phase consists of replacing the existing bituminous pavement with new concrete surfacing. Concrete paving on Phases 1, 1A & 1B is expected to begin next week. The new concrete typically takes between 7 and 14 days before it can be driven on so please use extra caution while paving is occurring and do not enter the area until the road is open to traffic. In preparation for the concrete paving, a string line is being set up and is used to guide the paving equipment and ensure the roadway is placed at the correct elevation at the designed concrete thickness. Additional media releases and detour routes are shown here.To sign up for updates specific to the 2021 Bridge Street Project, please visit Notify Me.2021 N Cedar Streetscape: Work this week included continued installation of sanitary sewer, storm sewer and watermain to get beyond the Rose Street intersection.
