Above is video from the naming ceremony on Monday for the tunnel boring machine [TBM] that will be used to dig one-mile twin tunnels on the northern part of the Crenshaw/LAX Line. In case you missed the news, the TBM’s name is Harriet.
The TBM when it is fully assembled underground will weigh 950 tons and have a diameter of 21.5 feet and will be 400 feet long. It should dig about 60 feet of tunnel each day. When the TBM reaches Leimert Park Station it will be disassembled and returned to the Expo construction yard, where it will be lowered again and launched to excavate the second tunnel.
