SR 99 tunnel virtual tour
Welcome to our virtual tour of the SR 99 Tunnel Project, the next closest thing to taking a stroll through the construction zone. Captured by photographer Bill Edwards in summer 2014, these images give you a first-hand look at the complexity and enormity of this project. Each of the thumbnails below will link you to a different section of the tour. For the best experience, we suggest you try the full-screen view. Please be aware that these images exist on an external website that is not owned or operated by WSDOT.
