Lookout Drive Reconstruction and Roundabout
City of North Mankato, Minnesota
Lookout Drive in the City of North Mankato between Commerce Drive and Howard Drive had serious safety concerns involving the TH 14 interchange. The roadway experienced numerous accidents and one fatality.
Bolton & Menk evaluated existing and future conditions of the roadway and developed alternative intersection and traffic control options. These alternatives were presented to the public. The option for construction of two roundabouts at the intersection of Lookout Drive and the exit/entrance ramps of TH 14 was selected over signalized intersections to address safety issues. The project also included ADA-compliant pedestrian facility design. The roundabouts have made these intersections safer with fewer injury crashes reported.
