Motorists should be alert beginning Monday, May 20 for construction crews installing delineator posts that are part of a safety improvement project in south-central Minnesota, according to the Minnesota Department of Transportation.

A MnDOT contractor is installing nearly 6,000 delineator posts in south-central 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 the night and adverse weather conditions when pavement markings may be hard to see.

In south-central Minnesota, the work will begin May 20 on Interstate 90. Portions of other highways scheduled for the work during the summer-long project will be Highway 14, Highway 60, and Highway 169. Motorists should be alert for work crews and lane closures during the work. Motorists should slow down and move over when encountering workers.
