LA Metro Westside Purple Line Extension Section One — Los Angeles, CA

Los Angeles Metro’s Westside Purple Line Extension Section 1 project is the first of three sections along the new 9.1-mile subway corridor. Parsons served as the prime designer and engineer of record (EOR) for the design-build team delivering Los Angeles Metro’s Westside Purple Line Extension Section 1—the first of three segments along the new 9.1-mile subway corridor. The 3.9-mile Section 1 extends the existing Wilshire/Western station to Beverly Hills, adding three new underground stations at Wilshire/La Brea, Wilshire/Fairfax, and Wilshire/La Cienega, plus a transition structure at Wilshire/Western.

Purple Line Extension Section One Completion

Construction on Section 1 reached substantial completion in mid-2025, marking a major milestone in expanding Metro Rail service to the Westside. All tunneling, cross-passage work, and systems installation are complete. Final testing and integration of power, train control, and communications systems have concluded, and Metro is preparing the line for revenue service by the end of 2025.

Street and station plaza restorations along Wilshire Boulevard are now complete, including new paving, lighting, traffic signals, and pedestrian improvements at all three station areas.

We are proud to have led the design of this transformative transit extension, improving connectivity, reducing travel times, and supporting sustainable mobility for the greater Los Angeles region.
