Statewide Interstate Plan
The South Carolina Department of Transportation (SCDOT) currently maintains 829 centerline miles of interstate. In addition to these maintenance activities, SCDOT is also responsible to address the interstate capacity needs in our state. This includes both the reconstruction of existing interstate interchanges, as well as providing additional travel lanes or alternative transportation options where the existing level of service has reached capacity.
Currently, the interstate system in South Carolina has 45 centerline miles of capacity needs. By 2030, to maintain an acceptable of level of service, that number will grow to 445 miles. In addition, close to 50 interstate interchanges across the state are in need of reconstruction to allow for today’s traffic flow. The challenge we face is the cost to provide for the construction of these additional capacity and reconstruction projects.
