New construction camera will capture south portal's ramps

Posted on Feb 5 2018 12:44 PM

We’ve installed a new time-lapse camera to capture work on the SR 99 Connections Project, which will finish building the ramps and roads that connect SR 99 to the new tunnel.

Seattle Tunnel Partners has completed some of this work, and the remaining work will occur in their existing work zones at the tunnel portals (near the stadiums in the south and near Seattle Center in the north). A new contractor, Scarsella Brothers Inc., will complete this work.

Our newest construction time-lapse camera, "SR 99 Connections South," captures a wide view of the tunnel’s south portal (click to see the camera):

The circled structure above is where southbound traffic will exit the tunnel. The rendering below shows that same tunnel exit in relation to the completed south portal.

SR 99 Connections will start work this month along East Frontage Road South and South Royal Brougham Road, just to the west of Safeco Field. Crews will be installing drainage, illumination and signals, as well as building roadway, curbs and sidewalks. Crews are scheduled to complete this work by the end of May.

If you live or work near the north end or south end construction areas, you can join the SR 99 Connections construction email update list by sending an email to viaduct@wsdot.wa.gov
