If under ORS 374.005 to 374.095 any existing highway or section of existing highway is converted into a throughway, by reason thereof real properties then occupied and used are affected and such abutting real properties are dependent upon the existing highway or section of highway for ingress and egress, the Department of Transportation shall provide a utility or service road to serve the properties. This utility or service road shall be constructed and maintained by the state at state expense and shall follow a location or route immediately parallel to and adjoining the throughway.
