Metro Purple Line (D Line) Extension,
Section 1 – Los Angeles, CA

The Purple Line Extension is a heavy rail subway line that extends the existing Purple Line adding seven new subterranean stations. The project is being delivered in three sections; Pacifica is providing support for Section 1, which is a 3.9 mile extension beginning in Koreatown at the Wilshire/Western station, and adding three new stations: Wilshire/La Brea, Wilshire/Fairfax, and Wilshire/La Cienega.
