Harriet's final breakthrough at Leimert Park Station

Harriet's final breakthrough at Leimert Park Station

On 06.04.2017 the TBM Harriet arrived at the Leimert Park Station completing the second tunnel of the underground section of the Crenshaw/LAX Line in  Los Angeles.

The TBM began its work on 27.04.2016 and completed the first tunnel last Autumn. Excavation of the second tunnel began on 29.11.2016 and each tunnel is one mile long. The tunnels run from the future Expo/Crenshaw Station at the Exposition and Crenshaw boulevards to the Leimert Park Station at Crenshaw and 43rd. There is also going to be a station in between at Crenshaw and Martin Luther King Jr. Boulevard.

Harriet excavated about 18.29 m/day (60 feet/day) and removed 144,250 cubic yards of soil for the second tunnel. A crew of 75 workers manned the TBM over 3 shifts, 5 days per week. The machine is named after Harriet Tubman, the abolitionist who freed slaves from the south via the Underground Railroad.

The Crenshaw/LAX Line will run for 13.68 km (8.5 miles) between the Green Line and the Expo Line and includes 8 new stations  (Expo/Crenshaw, Martin Luther King Jr,  Leimert Park, Hyde Park, Fairview Heights, Downtown Inglewood,  Westchester/Veterans and Aviation/Century) serving the communities of Crenshaw, Inglewood, Westchester and LAX. The project is to open in the Autumn of 2019.

A ninth station — separate from this project — will be added at Aviation Boulevard and 96th Streets. Crenshaw/LAX Line and Green Line passengers will use that station to transfer to alternative transportation being built by LAX that will serve the airport terminals. The airport is aiming to have the alternative transportation completed by 2023. Click here for a video and for further information https://www.metro.net/projects/crenshaw_corridor/. 15/17.
