The replacement of traffic signs that are at the end of their service lives will begin on April 29 along several highways in southcentral and southwest Minnesota, according to the Minnesota Department of Transportation.
Traffic signs located on various highways in Nobles, Rock, Blue Earth and Brown counties will be replaced.
MnDOT replaces traffic signs on a 15-year cycle to ensure signs are legible for motorists during the day and at night. Over time, traffic signs experience wear and tear, and frequently lose reflectivity in low-light conditions long before indications of their age are obvious in normal conditions.
Sign replacement on Minnesota 22 in Mankato will occur during evening hours to take advantage of reduced traffic impacts for the safety of the workers, as well as the traveling public.
There will be little impact to traffic on other state highways during the sign replacement. MnDOT does remind motorists to drive with caution and watch for crews working near the roadway. The project is expected to be completed by mid-August, weather permitting.
NTTK, Inc. was awarded the project with a bid of $849,906.64.
