Project update

Construction is anticipated to begin in downtown Prior Lake this August. The 13-21 staging map shows the anticipated stages and schedule for each stage. Work will begin with utility work at the West Ave/County Highway 21 intersection beginning August 5. Traffic will still be maintained on County Highway 21 while this work occurs. After this work is complete, Stage 1 (County Highway 21 between West Ave and Main Ave) will begin and will be closed to all traffic. Stage 1 is anticipated to last from late August to November. Crews will then go on winter work suspension and resume the construction of Stage 2 (Highway 13/County Highway 21 intersection) in the spring of 2020.

Local access maps will be provided on the project website in the coming days. Be sure to bookmark the project website and sign up for email updates on the project website so you can stay up to date during construction!
