Delineator posts being installed along four-lane highways statewide

WILLMAR, Minn. – The Minnesota Department of Transportation is installing delineator posts along all unlighted, four-lane rural highways. The statewide project is designed to aid traveler safety, especially during night and adverse weather conditions when pavement markings may be difficult to see. The posts provide visual separation between roadways and the surrounding land through the use of a square-shaped reflector set on point at the top of each post.

Posts are spaced 1/10th of a mile apart and will be installed on more than 1,300 miles of highways. The project began this fall and will be completed at the end of next summer, satisfying compliance with Minnesota’s Traffic Engineering Manual. More than 26,000 posts are being installed at a cost of approximately $1,000 per mile.

“This project provides a safety improvement worth investing in,” said Derek Leuer, traffic safety engineer, MnDOT Office of Traffic Engineering. “It provides a low cost, high benefit to drivers.”

In Southwest Minnesota, delineator posts are being installed along Highway 23 in Marshall and Granite Falls, as well as on US Highway 71 in Willmar, and along the four-lane portions of Highway 23 from Willmar to Paynesville. The posts will also be installed along US Highway 212 in Glencoe.
