press release:
King County Metro Transit will keep its buses chained up and on snow routing on Thursday, January 19, as the region recovers from significant snowfall, however transit operating conditions could change throughout the day, and bus riders are encouraged to watch for updates.

Depending on the roads and traffic, bus service will probably still be significantly disrupted and delayed on Thursday morning.

Metro plans to start the day operating the same level of service as on Wednesday, with 27 regular routes canceled. If travel conditions improve, service on these routes could be restored either early or during the day on Thursday. Before traveling, riders should check for the most current status of Metro service.

Due to the expectation of treacherous and impassable roadways on Thursday morning, Metro is scaling back some service in order to be able to operate the rest of its system as safely and reliably as possible.

The routes expected to be canceled on Thursday morning are:
2EX, 38, 42, 45, 46, 51, 53, 79, 114, 161, 162, 175, 192, 193, 197,
205, 210, 215, 216, 219, 224, 237, 251, 268, 277, 316 & 355.

Additionally, if schools are closed, Metro will cancel its Custom School routes.

DART service is expected to start Thursday on snow routing.

Information about route cancellations and revisions is available on Metro’s Snow & Ice page. Service could be revised or restored depending on actual travel conditions. Metro will notify subscribers if service is revised or restored.

Before traveling, riders are encouraged to check the Snow & Ice page for the most current status of Metro service. Updates to the online information begin as early as 4:00 AM, and continue as needed until conditions improve.

All other Metro service will operate via snow routing with schedule delays likely.
