Congestion Management Network
The Congestion Management Process focuses on the movement of people and goods over interstates, principal arterials, and other transportation facilities. These segments serve as the backbone to the region’s transportation network, and provide connectivity among the region’s transportation facilities, intermodal facilities, and activity centers.
The OKI CMN is composed of all facilities on the National Highway System (NHS); along with major roadways; and all other routes considered essential to regional mobility and continuity. The NHS is a network of strategic highways. This includes the interstate highway system and other roadways serving major transport facilities, such as airports, ports, and rail or truck terminals. In the OKI region, the NHS network covers more than 1,480 miles and carries 55 percent of regional traffic.
