If you haven’t seen the SR 99 tunnel’s south-end work zone lately, you should. The progress our crews are making to the west of Seattle’s stadiums is jaw-dropping, and it’s worth taking a look. Crews are building the launch pit and the facilities that will support the tunnel boring machine when it begins its underground journey this summer. Farther south, we are building supports for the new South Atlantic Street overpass. Keep your eyes open in the coming weeks as the bridge deck takes shape over SR 99.
If you want to experience construction in person, the best viewing area is on the bicycle/pedestrian path to the west of the construction zone, between South Jackson and South Atlantic streets. We’ve posted a series of informational signs on the fence along the path to help visitors understand what crews are up to. This map shows you how to get there. Of course you don’t even have to leave your chair to see tunnel crews in action. Our construction cameras give you the latest view of what’s happening in the north- and south-end work zones.
