Heavy Rail Transit


The Purple Line Extension (formerly known as the Westside Subway Extension) is the extension of the Purple Line from its current terminus at Wilshire/Western nine miles to Los Angeles' "second downtown" through the neighborhoods of Beverly Hills, Century City, and Westwood. The new line will ultimately add seven stations upon the completion of all three sections of the project using the design-build delivery method: Section 1 is a 3.9-mile long segment along the Miracle Mile to Wilshire and La Cienega Boulevards (including three stations), Section 2 is 2.6 miles from La Cienega to Century City (including two stations), and Section 3 is a 2.9-mile section through Westwood to the VA Hospital. The extension will consist of twin tunnels approximately 20 feet wide, located 50-70 feet underground. The tunnels will be constructed using the cut and cover method.

Section 1 stations will be located at Wilshire/La Brea, Wilshire Fairfax, and Wilshire/La Cienega. Section 1 also includes the procurement of 34 new heavy rail vehicles compatible with the existing system and improvements to existing Division 20 Rail Maintenance and Storage Yard to accommodate additional vehicles.
