Adi Emerges

Sandhogs complete tunneling the first phase of the Second Avenue Subway, reaching the Lexington Av-63 St station and breaking into the existing subway system. The 485-ton, 450-foot-long tunnel boring machine, nicknamed Adi, has a 22-foot diameter cutterhead and mined 7,789 linear feet in two tunnels, averaging approximately 60 linear feet a day.
