PORTLAND, Ore. (KOIN) — Highway 6 in Tillamook County has been closed as a result of icy road conditions, according to the Tillamook County Sheriff’s Office.

The highway closure, which was announced just before 3 p.m. Sunday, is from mileposts 28 to 38, according to authorities. It’s unclear when the highway will reopen.

Officials are warning about winter weather driving after “numerous” cars went into ditches on Christmas Day around Tillamook County roads, especially along Highway 6, according to a Tillamook County Sheriff’s Office Facebook post.

TCSO said there were “numerous cars into ditches, some resulting in serious injuries.”

“It was a real mess up there, it was hard to keep up with the carnage,” TCSO Forest Deputy Scott Griffith said. “We even had people driving on snow-covered forest roads with passenger cars that had no business being there.”

On Sunday, Forest Grove Fire also warned about icy road conditions on Highway 6 and Highway 26 in a Tweet.

As a winter storm warning remains in effect until Monday, Deputy Griffith advises drivers to stay home. “Really, if it’s not absolutely necessary to drive, then please don’t,” Griffith said.
