There’s power outages across the state and downed power lines all over. If you see a downed power line, move away from it and anything touching it. Keep 35 feet away. You can’t tell if a power line is energized by looking at it. Call 911 if there’s danger. Call your utility to just report the line.

4. The way you drive in heavy rain/flood conditions should look a lot different than how you drive normally. Most importantly: Obey road closure signs and if you can't see the road, DON'T DRIVE THROUGH THE WATER.

To build the new Portage Bay Bridges, traffic has to shift. 👇Three eras, explained in one photo:

Flooding continues affect many communities across Washington this week. Please stay safe, everyone.
A note about the SR 520 floating bridge: it’s designed to move with lake levels & stay stable with its watertight pontoons and anchor system. Here’s a closer look at those pontoons.

🌹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?! 👀
