The Los Angeles County Metropolitan Transportation Authority unveiled two new tunnel boring machines on June 17 for the authority’s $9.3-billion Purple Line Extension (PLE) project, which will connect subway transit service from downtown Los Angeles to the city’s westside by 2027.
The new TBMs will be used to dig two subway tunnels between downtown, and the Los Angeles neighborhood and business district Century City and the city of Beverly Hills for Section 2 of the 9-mile subway extension project. Section 2, of three, broke ground in February and will include 2.59 miles of track with two new Metro stations, Wilshire/Rodeo and Century City/Constellation.
