Statewide Interregional Corridor Study

While the 1997 Statewide Transportation Plan supports investments that enhance safety and timely travel between activity centers (regional trade centers), it defined the Interregional Corridor System as the entire 5,200-mile principal arterial system. The entire principal arterial system is too large as the interregional system to allow sufficient focus on the key transportation corridors throughout the state. In addition, previous Plans did not provide guidance on how these corridors should perform from a mobility perspective. The result has been a lack of attention on some major corridors and some inconsistencies between districts on how corridors are managed.

As a result, the Minnesota Department of Transportation (Mn/DOT) initiated the Interregional Corridor Study to identify important economic corridors in the state. The goal of the Interregional Corridor System is to maintain safe, timely and efficient transportation services between regional centers. Providing good transportation service to the main activity centers will improve or maintain productivity, reduce transportation costs and support the interdependencies that exist between different areas of the state and between Minnesota and other states and counties.
