More south central area highway speed limits to increase to 60 mph

MANKATO, Minn. — Nine more two-lane highway segments in south central Minnesota will have speed limit increases from 55 miles per hour to 60 miles per hour by the end of 2018. 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 for possible speed limit increases. MnDOT District 7, which consists of 13 counties, has completed the study on its rural two-lane highways.

The sections of highway which will have increased speed limits (when posted with black and white signs) are:

  • Hwy 4 from I-90 (Sherburn) to Sleepy Eye
  • Hwy 14 from Hwy 71 to New Ulm
  • Hwy 15 from the Iowa border to Winthrop
  • Hwy 19 from Fairfax to Gaylord
  • Hwy 19 east of New Prague to Hwy 13
  • Hwy 22 from Iowa border to Mankato
  • Hwy 59 from Iowa to Hwy 60
  • Hwy 62 from Fulda to Windom
  • Hwy 109 from Wells to Alden

A map showing which routes are already 60 mph and which are changing to 60 mph yet this year is available at mndot.gov/d7/images/2018speedlimitchanges55to60.pdf .

Hwy 22/111 from Nicollet to Hwy 212 will remain 55 mph speed limit until after construction in 2020 when pavement will be added to the shoulders with a rumble strip. 

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.

“The speed study gave MnDOT the opportunity to review speed limits on 55 mph state Hwys 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 highway, which looks at past crash history, physical attributes of the Hwy such as shoulder widths and access points, and what speed drivers are currently driving. In some cases, the study results in the speed limit staying the same.
highways changed to 60 mph in 2017 include:

  • Hwy 30 from Westbrook to Hwy 4
  • Hwy 83
  • Hwy 86
  • Hwy 169 from Iowa to Mankato
  • Hwy 257 (Hanska)

Highways changed to 60 mph in 2016 include

  • Hwy 68 from Morgan to Hwy 4
  • Hwy 5 from Hwy 19 at Gaylord to Hwy 212
  • Hwy 109 from Hwy 169 at Winnebago to Hwy 22 at Wells
  • Hwy 60 from Hwy 14 to Hwy 13 at Waterville

Minnesota has about 7,000 miles of two-lane roads that will be studied between 2014 and 2019.  A 2017 report on the evaluation of speed limits can be found at www.mndot.gov/speed/ .
