The Portland Bureau of Transportation has now activated its online map of major deicing routes. When roads are slick due to ice or snow, PBOT will update the maps to show which streets will see crews using deicers on the roadways. Check out PBOT deicer route map here.

PBOT has closed Southeast Clay Street between Water and Second avenues for emergency railway crossing work by Union Pacific. The closure is all hours and days beginning 7 a.m. Tuesday, Dec 5 and continuing for several days. PBOT warns the closure may need to be extended to allow for an upgrade to the road surface in the area

Heads up for tomorrow: Interstate 84 is scheduled for rolling slowdowns and delays in both directions near milepost 53 about noon Thursday, Dec. 7. This is the sixth in a series of rock blasting operations necessary to build the latest segment of the Historic Columbia River Highway State Trail.

The rolling slowdowns will delay traffic in both directions but the delays are expected to be shorter than for previous blast operations. The schedule may change due to unforeseen conditions.
