Looking south at construction of the future north portal of the SR 99 tunnel a few blocks away from Seattle’s Space Needle. The concrete deck is actually the ceiling, or lid in tunnel lingo, of the future southbound roadway going into the tunnel. In late summer 2014 the deck will be covered by the girders that will support a future section of Harrison Street.
