Built the world's longest floating bridge & we're heading west. Closure info: http://sr520construction.com. Vintage cover by SeatownNative (on X). Official WSDOT BlueSky account for SR 520.
The way you connect from I-5 in Seattle to eastbound SR 520 is changing next year as the Portage Bay Project continues improvements in the area.

Learn about upcoming traffic shifts and ask questions during our virtual meeting Thursday at noon.

🌹1️⃣ Step one in romanticizing your life: a walk on our bike & pedestrian bridge across SR 520. No cars, no traffic grind… just landscaped berms cancelling noise and a nostalgic playlist making you feel like the star of a 90s PNW rom-com.

Who else caught yesterday’s walk-worthy weather?! 👀

10/10 would ride again 🚏🚎

Steve caught up with bus rider Ashley, and she shared how new @kingcountymetro.bsky.social stops on the Montlake Lid have leveled up her commute. New connections all around! #BigTransferEnergy
