National Highway System (NHS) connectors are roads, which may be either state or locally owned, which connect intermodal facilities to major highways on the National Highway System. The NHS Connectors in this data layer are officially designated NHS freight connectors that serve any of three types of facilities: intermodal rail facility, port, and/or airport. These routes were digitized based on DVRPC's street centerline data set to correspond with the officially designated NHS Connector routes.
