The Virginia Department of Transportation (VDOT) is responsible for maintaining the third largest highway system in the country with more than 70,000 miles of roads. VDOT is in the process of streamlining its workforce to create an organization that serves in advisory, oversight, and management roles instead of an active public works provider. Currently, VDOT outsources 58 percent of its interstate maintenance. By 2009, the private sector will maintain all interstates in Virginia.8 This trend towards transportation maintenance by the private sector with VDOT oversight demonstrates VDOT's efforts to concentrate its limited finances on funding and executing transportation projects and maintenance and less on overhead.
