The breakthrough finishes the east drive of the Gotthard twin tunnels, which are among several being built through the Alps. The west tunnel’s breakthrough is scheduled for next spring. The joint-venture Tunnel AlpTransit Ticino (TAT) made the breakthrough at the tunnel’s midpoint, connecting to the awaiting “Sedrun” stretch. The tunnel is expected to start rail operations in late 2017 at an estimated cost of $10.3 billion.
