One year ago, construction crews unburied the SR 99 tunnel's northbound on-ramp near the stadiums. It had been built and then buried for several years while SR 99 bypass traffic drove over top of it.

We are investigating a leak coming from above the southbound lanes of the SR 99 tunnel, it is still safe to travel through. Monthly maintenance is scheduled for this direction at 10 p.m. tonight. We will use this closure to determine next steps with our contractor.

The SB SR 99 tunnel is open after an overnight maintenance closure. Our maintenance crews were able to create a temporary fix for the leak above the roadway. Our contractor will be out over the next week to make a permanent repair.

Reminder: the SR 99 tunnel is closed southbound TONIGHT so crews can repair the leaking grout port and conduct other routine maintenance work. 10 p.m. Fri to 8 a.m. Sat

In South Lake Union, we've opened new signalized intersections on 7th Ave N at Thomas and John Streets. Left turns remain prohibited as final phase of work, in median, begins. wsdot.wa.gov/Projects/Viadu…

Bob Essex keeps providing great service at our Washington State Ferries terminals & toll booths during this emergency but he misses seeing so many regular commuters. He & his teammates work hard to keep our ferries safe for those who must travel. Thanks Bob! #wsdotheroes

Tina Robinson has been working incredibly hard to keep the Elma Rest Area as clean & safe as possible for truckers & other essential travelers. It's vital work to keep goods moving during this emergency. Great job, Tina! #wsdotheroes wsdotblog.blogspot.com/2020/03/keepin…

The weekend will be beautiful & the draw to go out & enjoy it will be high. We've adjusted our signs to encourage people to continue what we're doing. Limit non-essential travel & find ways close to home to enjoy the sun while keeping us all safe & healthy.

Marshall Warner spends his work days in engine rooms for Washington State Ferries, caring for the engines so those who must travel have a safe trip across the water. Thanks Marshall, we appreciate the work you and all your team is doing to keep everyone safe! #wsdotheroes

Emergency maintenance - like our WSDOT Tacoma bridge crew fixing a large pothole on the SR 507 Deschutes bridge - has been vital in keeping essential travel safe. The crew used protective gear to respond safely and quickly. Nice work team! #wsdotheroes

Crews have begun the final stage of filling Seattle's old Battery Street Tunnel. They are pouring low-density cellular concrete, a kind of "concrete meringue" that protects utilities but could still be dug through in the future. Learn more: wsdotblog.blogspot.com/2020/07/final-…

We retired our construction cameras when our viaduct work wrapped up, but Waterfront Seattle is your new go-to source for all your construction camera needs.👇
