Before trains head out into service, they spend time behind the scenes getting cleaned, inspected, and prepared for the day ahead.

Montlake folks! 📣 We don’t want this to be you!😅
Heading to Montlake from I-5 Sept. 12–19? Take an alternate route before entering eastbound SR 520. Once you’re on eastbound 520, you’ll cross Lake Washington and pay the toll.

PLAN AHEAD: the Mariners play at 1 PM, and the Seahawks return home at 5 PM.
Heading to the game? Use transit for a low-cost trip. Biking and scooting also may be a great option.
Expect extra traffic and slower travel times if you're driving.

Last night we celebrated the opening of our new dedicated bus lane for the 8 bus on Denny by doing the obvious thing: racing it again. Last summer, Seattleites raced the bus on foot and beat it. This time around, with the lane up and running, it wasn’t even close.
