Since a state highway renumbering, which established the current state route system, the Bloxburg Valley Department of Transportation has decommissioned one state route. Once a highway has been decommissioned, the highway is turned over to the local county or city that it is in, they are then responsible for all maintenance on the former highway. All former highways are codified in Bloxburg Valley law.
