SIOUX FALLS, S.D (KELO) — I-29 is slippery and drivers should use caution this morning, the Lincoln County Sheriff’s Office advised Friday morning.

Authorities say that there were several crashes last night including an injury crash at the Harrisburg exit.

The South Dakota Highway Patrol is investigating the crash.

Vermillion Police posted a photo of a car on top of a snowbank Friday morning. The driver had cleared snow from the windshield but when snow fell from the roof of the car onto the windshield, it obscured their visibility.

“Please be careful traveling anywhere this morning and rid as much snow as possible from your vehicle,” police cautioned.

In Minnehaha County, the Sheriff’s Office said that road conditions are “poor with snow and ice” but expected to improve throughout the day as plows make their way through the county.
