Across the state, crews are working around the clock to clear the roads. Nearly every highway was affected by challenging conditions over the past few days with major impacts to Interstates 5 and 84 on Sunday afternoon. In the Portland Metro area, our crews are working to remove downed trees, snow and ice. Widespread power outages mean that many electronic road signs and traffic lights may be out. Treat traffic signals that aren’t working like a four-way stop. Never drive over downed power lines. Intermittent closures and delays on roads in Portland are likely. Snow and ice still blanket much of the Willamette Valley. Temperatures have not risen above freezing for much of the state. In areas where snow and ice began to melt today, be prepared for slick conditions as temperatures fall tonight. Northbound Interstate 5 near Cottage Grove is experiencing extended delays. Multiple vehicles have spun-out or slid off the road causing backups. Avoid the area if possible. Many sections of highway west of the Willamette Valley remain closed due to hundreds of downed trees. Some of these areas could take days to reopen. Temperatures are expected to remain low, and freezing rain is in the forecast for Tuesday. Most crews remain on 12-hour storm shifts to give our highways the most coverage possible. For the latest state highway information and to see current closures, visit Tripcheck.com.
