Regional Trade Centers
Interregional Corridor System
The IRC system connects the largest regional trade centers in Minnesota with each other and with neighboring states and Canada. This system consists of Greater Minnesota’s most heavily traveled roads, accounting for only 2 percent of all roadway miles in the state (2,960 miles), yet carrying about 30 percent of all statewide travel.
The IRC system is an essential transportation network for moving freight and supporting businesses. Safe and efficient IRC connections provide access to markets and services and facilitate recreational travel, improving quality of life. Congestion on IRCs negatively impacts travel time, reliability, safety conditions, fuel costs, and the state’s economic competitiveness.
Performance on the IRC system is measured as the percent of corridor miles in Greater Minnesota that operate within 2 miles per hour of their corridor target speed. Each corridor has a target of 55, 60, or 65 miles per hour average travel speed from end to end.
For more information on how the IRC system fits into MnDOT’s investment priorities, refer to the 20-Year State Highway Investment Plan. For IRC performance information, refer to the current Annual Transportation Performance Report.
