Trunk Highway 212 Expansion

Trunk Highway 212 Expansion


Project Challenge

This unique design-build project incorporated urban and rural highway design in the Twin Cities metro area along a previously undeveloped highway corridor. The project included seven interchanges, 29 bridges and multiple waterway crossings. The need to provide efficient transportation for a rapidly growing population meant that a new alignment for TH 212 was essential to meet the needs of the southwestern suburbs as Hennepin and Carver Counties continue to grow.
