About this project

The pavement on I-90 is old and in need of repair. Constructed in the 1970’s the bridges are approaching 50 years and nearing the end of their service life. MnDOT will invest $50 million in savings and $30 million of District 7 funds into the rural interstate system to improve performance. The $80 million investment will improve 120 miles of some of the poorest interstate pavements and an additional $20 million will be invested to repair the bridges.
