- County Highway 12 from just west of Old Wildwood Road to just east of Birchwood Road in Mahtomedi is tentatively set to close on Monday, May 9, 2022. During the road closure, there will be no access to Old Wildwood Road or Birchwood Road. Access will be maintained at Lincolntown Avenue, Ridge Way, and Wedgewood Drive.
- The closure is necessary to safely replace a deteriorated culvert connecting the north and south portions of Lost Lake and to widen County Highway 12 to accommodate turn lanes at Birchwood Road and Lincolntown Avenue. The closure is expected to run into the Fall of 2022. Drivers are encouraged to use the posted detour shown below.
Advance notice of the full closure will be provided via road signage, the project website, and social media. To sign up for construction updates, visit the project website at www.co.washington.mn.us/wildwoodroad
