Road Usage Charge Assessment

In 2012, the Legislature directed the Transportation Commission, in close cooperation with WSDOT and with guidance from a multi-stakeholder steering committee, to conduct an assessment of Road Usage Charging and determine if it is feasible. Road Usage Charging (RUC) is the notion of charging users of the road system a per mile charge, as opposed to our current system in which we pay for our roads via a gas tax that is assessed on a per gallon basis at the time we purchase our fuel.

Route Jurisdiction Study

The Route Jurisdiction Study was directed by the Legislature in 2023 and was issued in July 2025.  The study assessed the current state highway inventory and local roadway designations to determine if changes are needed in jurisdictional assignment between the state, county, and city road systems. And it also reviewed current criteria used to define the state highway system to determine if this criterion continues to be applicable.
