Sound Transit service in winter weather


Buses follow normal routes as long as the streets are safe for travel. Some buses may be running on snow routes and others may be canceled. Snow routes may change depending on road conditions. Snow route information here - is subject to change, sign up for rider alerts for most up-to- date information.

Be aware of at-risk bus stops:

  • In severe snow and ice, buses often avoid hills or other safety hazards.
  • If there's no traffic going by your bus stop, walk to a stop on a busy street.
  • If your bus stop is in the middle of a hill, walk to the bottom where the operator can safely stop.
  • Stand back from the curb until the bus comes to a complete stop. Buses can slide sideways in slippery conditions.
  • Keep in mind that to avoid getting stuck, your bus may not pull all the way over to the curb.


Link and Sounder trains operate regular commuter service during cold and icy weather. Some emergencies, such as mudslides, can cause service to be canceled. Plan ahead, and be aware of your alternatives in case your train is canceled. You can use the trip planner to find options.
