Survey work on Hwy 23 from Cottonwood to Granite Falls begins April 30
WILLMAR, Minn. – Motorists may encounter reduced speeds and delays beginning April 30 as survey crews work along the shoulders on Hwy 23 from Cottonwood to Granite Falls.
Crews from Continental Mapping Consultants will be using Mobile Lidar to survey Hwy 23 for a future stringless paving project. They will be placing control panels that look similar to painted arrows on the road surface approximately every 700 feet.
“This is the first time we have used this technology,” said Barry Anderson, land management engineer. “The innovative use of laser survey technology provides us with fast data collection, with less risk to surveyors and the traveling public.”
Mobile Lidar Mapping produces high-accuracy mapping in a safe, efficient manner by obtaining survey information within the flow of traffic.
