State Aid Rules
The state aid rules were established to provide counties and cities minimum standards for roads and bridges on the state aid system. They carry the force of law. These rules cover many items from designation and revocation of state aid routes; contract bidding requirements; variances from the standards; local road research; minimum maintenance requirements; geometric standards; pavement structural strength; natural preservation routes, bicycle path standards and more.
The rules were first adopted in 1957 and has since been revised numerous times by local agency engineering and government representatives. These revisions are typically done to adapt to changing environmental, economic, social and/or engineering conditions.
The current State Aid Rules was adopted on October 30, 2017.
