TheSource: Video: Harriet the Crenshaw/LAX tunneling machine begins digging under Crenshaw Boulevard



The first six months of 2016 were full of milestones for the Crenshaw/LAX Line. The project celebrated reaching its halfway mark in May and construction is now ongoing throughout the entire 8.5-mile project alignment.
The other major development this year has been the progress of Harriet, the project’s tunnel boring machine. The machine was ceremonially named and its pieces lowered underground at the Expo/Crenshaw excavation site earlier this year. After months of assembly and testing, the machine began tunneling under Crenshaw Boulevard in late April.
The time-lapse video above captures the machine’s launch and first month of excavation of the first of two tunnels.
The next time we’ll see the 950-ton machine will be when it breaks through the excavation site at the future Martin Luther King Jr. Station at MLK Jr. and Crenshaw boulevards. From there it will continue south to the Leimert Park Station excavation site, where it will then be returned to Expo/Crenshaw to begin digging the second tunnel.
You can follow the Crenshaw/LAX project on Twitter here.
Harriet also has her own account.
