Here are updates from the Seattle Department of Transportation:
SDOT continues working to prevent freezing on snow routes:
Currently the City has 17 trucks with salt spreaders and two flusher trucks deployed. Snow routes are in good condition. There was no significant re-freezing of cleared roadways during the past 24 hours. There are no significant problems on the snow route network. The Alaskan Way Viaduct and the West Seattle High Rise Bridge are bare and dry. Focus is on reopening closed roads. The Seattle Police Department and SDOT are working to review roads currently closed and will update the list online. The City will focus on efforts to prevent re-freezing, address trouble spots on Level 3 routes, and bring more roads off the closed list. Because of the possibility of precipitation today leading to the formation of black ice tonight, some roads will remain closed. 24 hour shifts will continue through Thursday, November 25.
