And we have a new tunnel!

On April 7, Metro’s tunnel boring machine completed the second tunnel for the Metro Crenshaw/LAX Line. The below video shows the machine, dubbed “Harriet” by the transit authority, chewing through the final wall of rock and dirt.

Work on the second tunnel began on November 29 connecting “the future Expo/Crenshaw Station at Exposition and Crenshaw boulevards to the Leimert Park Station at Crenshaw and 43rd.” Harriet excavated roughly 60 feet of the one-mile tunnel per day. A total of 144,250 cubic yards of soil were removed as the machine progressed.

If you’ve been following Harriet on Twitter you likely knew this moment was close at hand. Here’s a second video from the machine’s twitter feed:

The full project is expected to be finished in late-2019. Once finished, the Crenshaw/LAX Line will connect 8.5 miles between the Green Line and the Expo Line. The eight new stations on the line are listed below.

1. Expo/Crenshaw
2. Martin Luther King Jr.
3. Leimert Park
4. Hyde Park
5. Fairview Heights
6. Downtown Inglewood
7. Westchester/Veterans
8. Aviation/Century

A team of 75 construction workers operated the machine over three shifts, five days a week. As the below photo shows, they’re understandably happy about this recent breakthrough.
