2017 Safety Assessment

  • What we heard from the community:
  • Concerned with serious and fatal crashes at the Hwy 23 and Hwy 9

intersection.

  • Traffic needs to keep moving on Hwy 23, especially trucks.
  • It is difficult for trucks to wait in the median.
  • The area needs to be improved for walkers and bikers, especially near the

school.

  • The Hwy 23 and Hwy 9 intersection is congested and has back-ups.
  • Keeping the right-turn acceleration lane heading towards Spicer is important.
  • Future development along Hwy 23 needs to be considered.

2017 Safety Assessment Recommendations

  • After a thorough study of the intersection and seeking extensive feedback from

the community, a J-turn was recommended at the Hwy 23 and Hwy 9 intersection.

Construct Roundabout

Alternative dismissed because:

  • Does not maintain mobility corridor function
  • Higher cost alternative

Widen Median

Alternative dismissed because:

  • Minimal benefit compared to cost
  • Does not address driver confusion in median

Reconstruct Median and Install Traffic Signal

Alternative dismissed because:

  • Does not maintain mobility corridor function
  • Does not address driver confusion in median
  • Can introduce severe rear end crashes

Construct Flyover

Alternative dismissed because:

  • High cost alternative
  • Does not address all movements
  • Impacts local access on Hwy 9
  • High Right of Way impacts

Traffic Volumes at Hwy 23 and Hwy 9

3/10/2020 9 New London Hwy 23 and Hwy 9| www.dot.state.mn.us/d8/projects/hwy23newlondon

  • Most of the traffic at the

intersection is traveling from New London to Spicer/Willmar. (70%)

  • Only drivers traveling from New

London to St. Cloud will need to use the U-turn.

  • A majority (over 90%) of the traffic

traveling through the intersection today will not have any changes to the route they take.

SLIDE 11

Why do J-turns work?

  • Drivers only have to be

concerned with one direction

  • f traffic on the highway at

a time.

  • Drivers don’t have to wait

for an opening in traffic in BOTH directions to cross the highway.

SLIDE 12

How do J-turns work?

  • Drivers approaching a divided

highway from a side street are not allowed to make left turns or cross the highway.

  • Drivers will, however, have to

travel further (about 800 feet) to make this movement, which increases overall travel time by approximately 30 seconds.

J-turns as a safety improvement in Minnesota

  • MnDOT has been installing J-turns in Minnesota since 2010.
  • A 2012 nationwide safety study of J-turns showed a 70%

reduction in fatal crashes and a 42% reduction in injury crashes

  • A safety study conducted in 2017 showed that

J-turns in Minnesota offered the following safety benefits:

  • An over 90% reduction of fatal and serious injury right-angle

crashes

  • 77% reduction of all severity right-angle crashes
  • 50% reduction of injury crashes
  • 41 have been installed in Minnesota with 23 more planned.
