Seasonal closures · Washington
4 roads in Washington close for the winter on a schedule the agency publishes. Each page below shows what the WSDOT feed is posting for that route right now and quotes the closing and reopening dates from the agency's own page. The dates move with the snow. Storm closures on roads that stay open all winter are on the Washington road conditions page.
Closing date varies by year. The 2025 closure was Dec. 4.
SR-410Usually closes mid-November and reopens late May.
SR-123Usually closes mid-November and reopens late May.
SR-542Usually closes with the first snow (Oct. 15 in 2025). Reopened June 10 in 2026.
A seasonal closure is a gate the agency locks for the winter, not a storm closure. WSDOT posts storm closures and chain rules in its feed, and those show on the Washington road conditions page. A seasonal gate is announced on the agency's page and sometimes in the feed too. Each road page reads the feed for its route and lists whatever is posted, and says plainly when nothing is.
Closing dates in these pages are the ones the agency gives, with the date MileCheck read them. None of them is a prediction. When an agency has not posted dates for the 2026-27 winter, the page says that.
