MINNEAPOLIS (WCCO) – Icy roads may be to blame for a multi-car crash early Friday morning that caused a significant traffic backup in the south metro.

The Eagan Police Department says there was a multi-car crash shortly before 6 a.m. on northbound Highway 77 in Eagan, at the intersection of Interstate 35E.

Roads in the area were “very icy” due to overnight snow, police said. According to the Minnesota Department of Transportation, the crash involved 12-15 cars.

The State Patrol says one person was brought to a hospital with non-life-threatening injuries.

Northbound Highway 77 was closed for more than an hour amid the early morning rush. Emergency vehicles also blocked part of the southbound lanes.

Meteorologist Mike Augustyniak says the light overnight snow likely created slick conditions on ramps and bridges in the south metro as temperatures hovered around freezing.
