Major Project of the Year (over €500M)
Purple Line Extension, Section 1
The Skanska-Traylor-Shea Joint Venture (STS) is constructing the $1.9 billion design-build of the Purple Line Extension, Section 1, in Los Angeles.
This is the first of three projects to extend the Purple Line from Wilshire / Western Station to Santa Monica, a tunnel project that has been in the works for over 60 years!
This portion of the project will add 3.92 miles to the Purple Line, beginning at the Wilshire/Western Station. The twin tunnel alignment travels beneath Wilshire Boulevard, and underground stations are under construction at Wilshire/La Brea, Wilshire/Fairfax, and Wilshire/La Cienega. The tunnels, mined by two Herrenknecht TBMs, are 35,750 linear feet long with an inner diameter of 18.8 feet.
The project also includes train control and signals, communications, traction power supply and distribution, and fare collection systems.
