Seasonal Travel Information

Public Works operates 24/7 to provide emergency support during fire, flooding, and icy seasons. To report an emergency, use the after hours number for Thurston 9-1-1 Communications (TCOMM) (360) 704-2740.


Watch for road closures in fire prone areas. Do your part to prevent fires. Do not throw burning material from a car window or onto the ground. Don't leave fires unattended.


Do not attempt to drive on a flooded street. The water can be deeper or moving faster than you anticipate. Also, it is dangerous and illegal to drive around a "road closed" sign. Fines are greater than $400.

Icy Conditions

Though Public Works crews mitigate icy road conditions by spraying anti-icing solution to roadways, it is still important to slow down and drive carefully to avoid loss of traction and traffic collisions.

Roads are responded to in a prioritized order, with arterials, major collectors, and routes to emergency locations first. Click here to view the map.
