PORTLAND – A semi-truck slid on an icy section of I-84 early Monday morning, causing a major backup for westbound traffic.
All westbound lanes were closed on I-84 at Northeast Marine Drive just before 8 a.m. because of the jackknifed semi-truck. Traffic began to move around 10 a.m.
Traffic: Alert updates
Drivers were warned to stay home if possible and avoid traveling on area roads until temperatures climb consistently above freezing and the ice melts away.
"If the roads look wet, it may be ice. So be careful out there," said Don Hamilton with the Oregon Department of Transportation.
Side streets had the most slick spots but the city was working to get main thoroughfares cleared with plows. Crews were also spreading de-icer and gravel and clearing storm drains.
I-84 eastbound had even more problems Monday with freezing rain.
A Freezing Rain Advisory for the central Columbia River Gorge and Upper Hood River Valley warned of possible freezing rain, sleet and snow through Monday night.
Chains are required for all big rigs headed east on I-84.
"I was driving 20 miles an hour with chains all the way from basically Colburn to Troutdale," said trucker Daniel Cundif. "It was just a really slow drive and then you've got these people just driving like idiots and wrecking."
