The last section of the Purple Line Extension will add two additional stations at Wilshire/Westwood and on the U.S. Department of Veterans Affairs property. Tutor Perini is also the Design-Build contractor for the Purple Line Extension Section Three Tunnels contract, which will add 2.56 miles of new rail to the Purple Line. 

The Westwood/UCLA station will be located under Wilshire Boulevard between Veteran Avenue and Westwood Boulevard. The Westwood/VA Hospital station, including two crossovers, will be located to the west of the I‐405 Freeway, south of Wilshire Boulevard, and will include a pedestrian bridge to the south of Wilshire. 

Both stations will be constructed of cast-in-place concrete in a subterranean environment in the middle of major urban shopping districts and commercial city streets. Tutor Perini will design not only the major support-of-excavation (SOE) down to a depth of up to 100 vertical feet below street level but also temporary traffic decking system to carry vehicular traffic over the station's box cavities during construction.
