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 last revision to Minnesota Administrative Rules under Chapter 8820 by the Rules Advisory Committee was adopted on October 30, 2017 and printed for distribution on February 2018. In 2021, the 8820 Rule was republished electronically with one minor error correction and is the current version.
