PORTLAND, Ore. (KOIN) — Icy conditions led to a crash that sent 4 vehicles down an embankment on Sunnyside Road Southeast in Marion County.

Rescue efforts included fire crews and Marion County deputies. Drivers were urged to avoid the area shortly after the crash early Sunday.

But early Sunday evening, Marion County authorities urged drivers to stay off the roads from midnight into the early morning hours because of the icy conditions.

“We have seen and are going to continue to see for several days to come extremely cold temperatures down around freezing, which is going to make conditions dangerous and unpredictable throughout Marion County roadways,” officials said.

Since midnight, Marion County saw 11 different crashes, some with serious injuries.

Motorists are reminded to keep in mind the winter conditions as they drive.
