About the Seattle / Puget Sound cameras

Dense camera coverage through the Seattle core on I-5, I-90, I-405 on the Eastside, and the SR-520 floating bridge across Lake Washington. Ideal for timing notorious Puget Sound rush hours and watching the I-5 reversible express lanes.

Seattle has the deepest camera coverage in Washington — more than 550 WSDOT feeds across Puget Sound, gathered here on one live map. The marquee views are the lake crossings: SR‑520 rides the Evergreen Point Floating Bridge, at 7,710 feet the longest floating bridge in the world, while I‑90 crosses on a floating pair of its own — the Lacey V. Murrow and Homer M. Hadley bridges via Mercer Island. The daily which-bridge question is best answered by looking.

Beyond the lake, cameras line I‑5 through downtown and both suburban approaches, I‑405 through Renton, Bellevue and Kirkland, and the portals of the SR‑99 tunnel — the two-mile double-decker that replaced the Alaskan Way Viaduct under downtown. The south end gets SR‑167 down the Green River Valley and SR‑18 over Tiger Mountain, the freight shortcut to I‑90. A backup spotted on camera is a reroute you can still make.

And when a trip leaves the lowlands, the mountains take over: every eastbound route funnels onto I‑90 over Snoqualmie Pass (3,022 feet) or US‑2 over Stevens Pass (4,061 feet), each with its own corridor page — /i-90-snoqualmie-pass and /us-2-stevens-pass — showing every camera in drive order with the live WSDOT pass report. Seattle itself is a rain town, but the rare hard freeze is its own event: the hills ice over, and a camera on the grade beats any forecast.

Tips for the Seattle / Puget Sound cameras

  • Check both floating bridges before you commit — SR‑520 and I‑90 rarely jam equally, and the approach cameras show which crossing is actually moving.
  • Heading east in winter, check the passes before the weather apps — rain at lake level is often snow at the summits, and the corridor pages at /i-90-snoqualmie-pass and /us-2-stevens-pass show the whole climb.
  • On Seattle's rare snow or ice mornings, look at cameras on hills and bridge decks first — elevated pavement freezes long before the flats look slick.
  • Save the cameras on your daily drive as favorites so tomorrow's check takes one tap instead of a search.
  • Cameras show the road, not the rulings — official closures, restrictions and pass reports live on the WSDOT app and wsdot.wa.gov.

Frequently asked questions

Can I watch the SR‑520 and I‑90 floating bridges?
Yes — both Lake Washington crossings are covered: the Evergreen Point Floating Bridge carrying SR‑520, the longest floating bridge in the world, and I‑90's pair, the Lacey V. Murrow and Homer M. Hadley bridges via Mercer Island. Wind events and backups usually hit one crossing harder than the other, so a look at both approaches settles the choice.
Which Seattle freeways have cameras?
All the majors: I‑5 through the city, I‑405 up the Eastside, I‑90 and SR‑520 across the lake, the SR‑99 tunnel portals, and SR‑167 and SR‑18 through the south end. Coverage is thickest through the downtown core and the big interchanges, so a two-camera scan usually settles a route choice.
Does it ever snow in Seattle?
Rarely — but when it does, the city struggles. Seattle is built on hills, and even a light glaze makes the steep grades treacherous while the freeways stay merely wet. On a freezing morning, check cameras on the hills and elevated sections before trusting a green traffic map. The passes an hour east are a different world entirely.
Which pass do I take east — Snoqualmie or Stevens?
I‑90 over Snoqualmie Pass (3,022 feet) is the main road east — an interstate, and the lower, usually more resilient crossing. US‑2 over Stevens Pass (4,061 feet) is the two-lane northern route to the Stevens Pass ski area and Leavenworth. Both have dedicated pages — /i-90-snoqualmie-pass and /us-2-stevens-pass — with every camera in drive order and the live WSDOT pass report.
How current are the images?
Each camera is a recent still from WSDOT's traveler-information network, typically refreshed every minute or two rather than streamed. Reload the frame you're watching before making a call on a fast-moving backup.
Is this an official WSDOT site?
No — the images come from WSDOT's public camera feed, but this is an independent, non‑commercial travel tool. Official closures, restrictions and pass reports come from the WSDOT app and wsdot.wa.gov. For the rest of the state, the statewide map at /wsdot-cameras carries all 1,500‑plus WSDOT cameras.
