The two Tunnel Boring Machines (TBMs) for the Purple Line Extension Transit Project Section 1 will be used to dig two parallel tunnels that will connect three new stations betwen Koreatown and Beverly Hills.
The TBMs will dig side by side starting at Wilshire/La Brea in the Miracle Mile section of Los Angeles and continue towards Wilshire/Western in Koreatown. Then they will be disassembled for transporting back to Wilshire/La Brea and then reassembled for the last leg of their journey through Wilshire/Fairfax and finishing at Wilshire/La Cienega in Beverly Hills.
When will they start work?
The TBMs will start work in Summer 2018 after they have been assembled and tested.
