Some south central area hwy speed limits to increase to 60 mph next week
Highways impacted include sections of Highway 5, 60, 68, and 109
MANKATO, Minn. – Four two-lane highways in south central Minnesota will have speed limit increases from 55 miles per hour to 60 miles per hour by Friday, Oct. 21. The sections of highways with studies are complete are:
- Highway 5 from Highway 19 at Gaylord to Highway 212
- Highway 60 from Highway 14 to Highway 13 at Waterville
- Highway 68 from Morgan to Highway 4
- Highway 109 from Highway 169 at Winnebago to Highway 22 at Wells
The speed limit is effective when the new signs are posted. Existing stop conditions or urban environments are used for the transition in speeds so that motorists will see a posted sign.
“A speed study gives MnDOT the opportunity to review speed limits on 55 mph state highways in our area and identify those that can support a higher speed limit without compromising safety,” said Scott Thompson, MnDOT traffic engineer.
The increases are based on a traffic and engineering investigation of each location, which looks at past crash history, physical attributes of the highway such as shoulder widths and access points, and what speed drivers are currently driving. The increases are the result of a 2014 legislative mandate for MnDOT to study posted speed limits on all two-lane state highways and make recommendations.
In some cases, the study results in the speed limit staying the same. In south central Minnesota, approximately 600 miles were studied between 2014 and 2015. Of the roads studied, approximately 275 miles will be increased. Several more south central two-lane highways have the fieldwork complete and await final data analysis. These roads could have speed changes coming as early as this winter.
Minnesota has about 7,000 miles of two-lane roads that will be studied between 2014 and 2019. A 2014 report on the evaluation of speed limits can be found at www.mndot.gov/speed/ .
