MARSHALL – Motorists may encounter lane closures on Highway 68 in Marshall this week for overhead sign replacements, according to the Minnesota Department of Transportation. The closures will take place this week from Tuesday through Thursday, from 10:00 p.m. until 6:00 a.m. Work is being done overnight to minimize traffic impacts. 

The sign replacements in Marshall are part of a district wide project to replace signs along several state highways in southwest Minnesota. MnDOT replaces traffic signs on a 15-year cycle to maximize efficiency.  

According to MnDOT, many signs are more than 30 years old and no longer meet regulations regarding weight and measure. The public will notice that old and new signs may be in place simultaneously as the installation crew works ahead of the removal crew. Old signs are not immediately removed for safety reasons. 

District 8 in southwest Minnesota has 32,000 signs and approximately 2,100 signs are replaced each year. 

MnDOT encourages travelers to always drive with caution and to slow down in project areas for their safety and the safety of workers.
