Dresbach Interchange Wins ACEC/MN 2018 Engineering Excellence Grand Award
I-90 and US 61 Interchange in Dresbach, Minnesota
January 29, 2018
Congratulations to the Minnesota Department of Transportation and project partners for winning the American Council of Engineering Companies of Minnesota (ACEC/MN) 2018 Engineering Excellence Grand Award!
SRF led a multi-consultant team to deliver the final design of the $188M project for the I-90 and US 61 Interchange and new Mississippi River bridge in Dresbach, Minnesota. This tri-level interchange included more than three miles of retaining walls and several curved steel bridges that were designed to complement the aesthetics of the bluff area while greatly improving the safety and operation of this important interchange. The project’s beautiful setting in southeastern Minnesota required a complete understanding of the natural characteristics and uses of the area to provide a design sensitive to the unique riverine environment. SRF successfully partnered with two state Departments of Transportation and several federal agencies to introduce innovative construction techniques and contracting tools including performance-based geotechnical designs, traffic management, and rockfall protection.
