TH 52/TH 55/CSAH 42 Interchange

TKDA developed a new interchange and improved an existing interchange to improve traffic flow

The Dakota County Transportation Department needed to develop a new interchange and improve an existing intersection in order to prepare for the elimination of the TH 52/TH 55 interchange. In cooperation with MnDOT and the City of Rosemount, Dakota County hired TKDA for the second phase of layout development of the new interchange as well as the project scoping and preliminary engineering for the realignment and geometric improvements of the existing intersection of TH 55/CSAH 42.

TKDA developed a preliminary layout of a full cloverleaf interchange to replace the existing diamond interchange at TH 52/CSAH 42. TKDA also provided alternative concepts and cost estimates for frontage/backage roads to serve existing and future land uses. By using an alternatives evaluation matrix, TKDA compared the social and environmental impacts and cost of each alternative.
