Tunneling machine "Brenda" recently dug beneath Interstate 5, completing a southbound light-rail tube from the future Capitol Hill Station to the Downtown Seattle Transit Tunnel. The giant drill burrowed through glacial soil, boulders and groundwater without triggering the sort of underground slides that can cause sinkholes at the surface, said project director Joe Gildner.

All tunnels in the light-rail extension from Westlake Station to Husky Stadium have now been drilled and lined with concrete rings. Next, this cutterhead will be detached and pushed to the right on wooden skids, then lifted out by crane alongside the Paramount Theatre. Stations, tracks, signals and train tests must still be finished before the $1.95 billion tunnel opens for passenger service in fall 2016.
