WILLMAR — The Minnesota Department of Transportation (MnDOT) will conduct aerial mapping in southwest Minnesota during the upcoming spring season.  Weather permitting, the mapping work is scheduled to commence in early April and conclude by mid-May. The locations targeted for this project include: 

  • Highway 23: Stretching from Lyon County Road 7 to 300th Street in Marshall. 
  • Highway 19: Covering the area from Laser Avenue in Redwood Falls to Renville County Road 15 near Morton. 
  • Highway 12 and Highway 15: Encompassing a half-mile radius in each direction from the intersection in Dassel. 

This mapping initiative aims to document the existing infrastructure and landscape along with the MnDOT right of way, facilitating transportation planning and highway design. The mapping will be carried out once the snow has melted but before trees start to leaf out. 

Members of the public are urged not to disturb the temporary targets used for accurate aerial mapping. MnDOT crews will mark paved surfaces with large white “X” targets and employ plastic or fabric “X” targets on unpaved surfaces. These targets are essential for recording coordinate positions and elevations for the aerial photography company. Once the photography is completed, MnDOT will remove the temporary targets. 

Landowners within the targeted areas, where targets will be placed or located nearby, will receive direct communication from MnDOT. MnDOT emphasizes the importance of not removing or disturbing these targets. If relocation is necessary, individuals are encouraged to contact the District 8 Willmar Office at 320-231-5195 and request assistance from the Surveys department.
