A spring snowstorm that blanketed parts of Minnesota and Wisconsin overnight caused poor road conditions, leading to crashes and slowdowns across the region.

After earlier suspending all bus service, Metro Transit resumed operations just before 10 a.m.

Between midnight and 4 p.m., the Minnesota State Patrol says there have been 255 property damage crashes, 22 crashes that involve injuries, 364 vehicles off the road, 48 spinouts and 29 jackknifed semis. 

The University of Minnesota also paused campus transit services in the Twin Cities, but service resumed at 10:30 a.m.

According to the Minnesota Department of Transportation, as of 7 p.m., most Twin Cities and northern Minnesota highways are clear. Many roads on southwestern Minnesota are partially covered and some in south central Minnesota are completely covered.

MnDOT also reported at least two dozen crashes and spinouts in the metro alone. The Minnesota State Patrol says five of their cars were hit throughout the major mess.

"In my 14-year career with the state patrol, I don't think I've seen this many squads hit in one day as Wednesday, and that's in the course of 12 hours," Lt. Mike Lee said.

There were no major injuries, but there was a minor injury to the driver who hit a squad car on westbound Interstate 94 in St. Paul on Tuesday night.

"We don't place blame on road conditions. It's the people who are driving cars who are responsible to maintain control and drive appropriately on the freeway," Lee said.

Troopers to the south also had a tough night. Iowa State Patrol had at least two squads hit.

"Please, if you can wait, just wait. Wait until the roads get cleaned up and the weather conditions get better," Lee said. "If you're late, you're late. it's better to get there safely than not at all."

The snowstorm also caused hundreds of school closures and delays, including a full closure for the Anoka-Hennepin Public School District and virtual learning days for Minneapolis and St. Paul.

As of 12 p.m., snow totals at Minneapolis-St. Paul International Airport measured 9.5 inches, according to the National Weather Service.
