MnDOT installing delineator posts to SE Minnesota improve safety on four-lane highways

Delineator postROCHESTER, Minn. – Motorists should be alert beginning April 8 for construction crews installing delineator posts that are part of a safety improvement project in southeast Minnesota, according to the Minnesota Department of Transportation.

A MnDOT contractor is installing 5,540 delineator posts in southeast Minnesota along all unlighted, four-lane rural highways. The posts are installed about 1/10th of a mile apart. The statewide project is designed to aid traveler safety, especially during night and adverse weather conditions when pavement markings may be hard to see.

In southeast Minnesota, the work will begin April 8 on Interstate 35 near Elko and proceed south to the Iowa border. Portions of other highways in southeast Minnesota scheduled for the work during the two-month project will be Highway 14, Highway 21, Highway 13, Highway 65, Highway 218, Interstate 90, Highway 63, Highway 52, Highway 61 and Highway 43. Motorists should be alert for work crews and lane closures during the work. Motorists should slow down and move over when encountering workers.

The delineator post project is aimed at providing visual separation between road and the surrounding land through the use of a square-shaped reflector set on point at the top of each post. The project began in fall 2018 and will be completed at the end of summer 2019.

“This is a low-cost, high effectiveness initiative to aid motorists, especially during times of Minnesota weather that make it difficult to see pavement markings,” said Adam Wellner, MnDOT District 6 acting traffic engineer.
