TBM Angeli breaks through in Los Angeles

On June 1, the tunnel boring machine Angeli broke through at the Bunker Hill Station 110 feet underground. According to the LA Times,

The 1,000-ton, 400-foot-long machine began its subterranean journey four months ago in Little Tokyo. After breaking through a wall of earth at the planned Grand Avenue Arts/Bunker Hill Station on Thursday morning, the machine will veer left and continue digging through downtown's Financial District until it reaches 4th and Flower streets in a couple of weeks.

When the entire $1.75-billion project is completed in 2021, the S-shaped tunnel will allow commuters to use a single train to move from Long Beach to Azusa and from East L.A. to Santa Monica, linking some of the county's most far-flung residents without time-consuming transfers.

An interactive video allows you to view the breakthrough in 360 degrees.

LA Metro selected the Contractor Joint Venture of Skanska/Traylor with Mott MacDonald as the prime designer for this major and highly complex design-build delivery project. When completed, the line will allow for a single seat ride throughout Los Angeles County and will link LA Metro's entire 80-station system to Southern California's regional passenger rail system (Metrolink) that services 55 stations.
