INTER-REGIONAL CORRIDOR SYSTEM
According to the 2000 Inter-Regional Corridor Study:
Inter-Regional Corridors tie the state together. They support Minnesota's economic health by connecting people with jobs, distributors with manufactures, shoppers with retailers, and tourists with recreational opportunities.
