I-90 Austin Bridges Improvement Project - Minnesota Department of Transportation

As of October 17 2023 this project is in working drawings complete. I-90 Austin Bridges Improvement Project INFRA Award: $25,000,000 Austin, Minnesota Applicant: Minnesota Department of Transportation Project Description: The project will reconstruct eight bridges (five overhead structures, two mainline bridges, and one pedestrian bridge) and rehabilitate two mainline bridges along I-90. The project includes ramp connection and traffic signal improvements associated with the bridges, construction of a network of ADA accessible multiuse sidewalks and trails, and replacement of stormwater infrastructure. Project Benefits: Currently I-90 is a barrier between downtown Austin and neighborhoods north of I-90. Extensive equity-focused community outreach and public engagement conducted for this project identified the need for improved bicycle and pedestrian facilities. Additionally, the project is aligned with the state’s climate action and equitable development plans and improves resiliency and disaster preparedness along the corridor. The interchange and traffic signal improvements also address the high number of left turn related crashes and queuing issues, improving safety and reducing congestion. From 2024 to 2026, MnDOT is planning to replace or repair bridges at six sites along the I-90 corridor in Austin. The work will include bridges at: Oakland Avenue West (Hwy 105), replace in 2024 14th Street Northwest (Hwy 218 north), replace in 2026 Fourth Street Northwest, replace in 2024-2025 I-90 over Cedar River, replace in 2024-2025 I-90 over Sixth Street Northeast, rehabilitate in 2024-2025 21st Street Northeast (Hwy 218 south), replace in 2026
