Curved concrete pieces used to make the walls of the highway tunnel being dug along the Seattle waterfront sit near the white crane at center-left, used to move them in place, Tuesday, Feb. 11, 2014 in Seattle. The contracting team hired to dig the tunnel told the Washington state Transportation Department Monday evening that it will take months to fix broken seals on the world's largest tunneling machine, which is currently 60 feet underground, officials said in a statement.
