Sepulveda Transit Corridor

The Sepulveda Transit Corridor Project is a two-phased planned transit corridor project that aims to connect the Los Angeles Basin to the San Fernando Valley through Sepulveda Pass in Los Angeles, California, by supplementing the existing I-405 freeway through the pass. The corridor would partly parallel I-405, and proposed alternatives include heavy rail rapid transit (a subway) or a monorail line connecting the G Line in the Valley to the D Line and E Line on the Westside, and the K Line near Los Angeles International Airport.

I-405 over Sepulveda Pass between I-10 and US 101, which the proposed transit line will run parallel to, is the busiest highway corridor in the United States, serving 379,000 vehicles per day.

Currently, LA Metro services the Sepulveda Pass corridor (which is essentially phase 1 of the Sepulveda Transit corridor) with bus Route 761, which uses Sepulveda Boulevard to traverse Sepulveda Pass. Its southern terminus is Expo/Sepulveda station on the E Line, and connects to the G Line at its Van Nuys station and Amtrak and Metrolink at their Van Nuys station, before terminating at Sylmar/San Fernando station. It takes about an hour to connect the E and G Lines. Route 233 serves Sepulveda Pass at night.

What is currently designated as phase 2 of the project is served by Culver CityBus lines 6 and Rapid 6 via Sepulveda Blvd, with the latter only operating weekdays. The lines' northern terminus is the UCLA Gateway Plaza (Westwood/Strathmore). Both lines 6 and Rapid 6 meet the aforementioned Metro 761 in Westwood Village at the Westwood Blvd/Weyburn Ave intersection and at the 761's southern terminus, the Metro E Line's Expo/Sepulveda station. The southern terminus is the Aviation/LAX C line station. As such, the lines indirectly serve LAX, requiring a transfer to a free shuttle bus that serves the station and LAX terminals. They will be rerouted to the LAX Metro Transit center station once it is open, as the station will feature bus bays and direct connections to the LAX terminals by way of the LAX Automated People Mover. Rapid 6 is unique in that it has traffic intersection signal priority in the City of Los Angeles, whereas most agencies do not have signal priority outside of their base city. Line 6 completes its run as scheduled in 1 hour 4 minutes with average traffic while the Rapid 6 completes its run with 15 minute headways in 54 minutes as scheduled with average traffic.

Total transit time from the Aviation/LAX C Line station to the Van Nuys G Line Station with the aforementioned bus service is about 2 hours plus transfer time. The completion of both phases of this project is estimated to return a total transit time through the whole line of about 45 minutes.
