Work continues this year on the University Link light rail tunnels. This photo shows the gantry cars lined up and connected to the tunnel boring machine that is being re-assembled to dig the northbound tunnel between Capitol Hill and downtown Seattle. The gantry cars carry several items including the electrical transformer for the TBM, grout tanks and pumps and utility piping. U-Link tunneling will be completed in 2012 with passenger service expected in 2016.

Then it will be heading north through Shoreline and Mountlake Terrace to Lynnwood as the North Link.
