Tunnel borer now expected to break through at midnight

Sound Transit’s tunnel-boring machine “Togo” is now expected to complete its breakthrough at the site of the Capitol Hill Station around midnight, rather than 9 p.m. as earlier announced.

Workers have slowed the pace to even less than the early afternoon rate of 5 feet per 90-120 minutes, to show extra caution in the last few feet, said spokesman Bruce Gray.

The machine will emerge in this pit at the future station site.

Right now, the machine is under the sidewalk at John Street, grinding with its rotary head cutting  through concrete grout along the north station wall.

Meanwhile, muck is being scooped out from another part of the transit tunnel, being bored from this station to the downtown transit tunnel.

The old Capitol Building, above the tunnel route, has not shown any damage, as its owner had feared.

Link rail service from Westlake Center to Capitol Hill and Husky Stadium is scheduled to begin in fall 2016.
