completed

The first segment of the multi-phase D Line Subway Extension, featuring 3.9 miles of underground rail and three new stations, begins service as Los Angeles advances major transit infrastructure expansion. The extension delivers new subway infrastructure between Wilshire/Western and Beverly Hills, including stations at La Brea, Fairfax, and La Cienega. Parsons Corporation served as lead designer and managed final design work. The project is part of a broader nine-mile subway expansion beneath Wilshire Boulevard aimed at reducing congestion, improving air quality, and expanding regional mobility.
