The ice from the holiday weekend has stuck around and even with road crews applying deicer some areas remain slick. Interstate 5 northbound near Terwilliger is a trouble spot with a five-car crash at 6:15 a.m. that blocked the left lane.

Update 7:40 a.m.; Crash cleared. Left lane is icy. Use the middle and right lanes.

All lanes of southeast 82nd Avenue (OR 213) are closed in both directions from Southeast Bybee Boulevard to Cooper Street while Portland Water Bureau crews repair a water line break. Travelers should use local streets as a detour. No time has been set for reopening. Often these types of repairs take several days.

Washington County continues to enforce snow zones on Southwest Barnes and Cornell roads and on 175th Avenue. Traction devices are required on these roads in the snow zones.

PBOT continues to apply deicer through the morning:
