Metro is making strides to improve travel between the San Fernando Valley, the Westside and Los Angeles International Airport (LAX). The natural barrier created by the Santa Monica Mountains means that most people traveling between these areas are funneled primarily onto the I-405 Freeway, already ranked as one of the most traveled urban highways in the nation. More than 400,000 people travel through this area every day to commute to work, school, and other destinations along the freeway and beyond.

Project Status

In Fall 2019, Metro completed a two-year Feasibility Study (Study) evaluating a number of alignments and station locations for a range of high-capacity rail transit alternatives between the San Fernando Valley and LAX with connections to existing and planned Metro bus and rail lines, including the Metro E Line (Expo), G Line (Orange) and future Metro Purple (D Line) Extension and the East San Fernando Valley Light Rail Transit Project.

The project has been identified as a good candidate for delivery through a public-private partnership (P3), which, if feasible, offers the potential for greater innovation, higher performance with reduced risk and cost, and potential schedule acceleration.

On October 31, 2019, Metro issued a Request for Proposals (RFP) seeking assistance from the private sector to jointly develop plans for the Sepulveda Transit Corridor Project. Metro's RFP seeks a pre-development agreement (PDA) with up to two private sector proposers to assist in the planning and design of this mega-project. Once project development is complete, the private sector project developer would have an opportunity to submit a proposal to build and operate the line, potentially accelerating construction and improving project performance.

Update on Sepulveda Transit Corridor and opportunities for public input (August 2020)


The Sepulveda Transit Corridor is part of the Measure M expenditure plan, with approximately $5.7 billion for new transit service to connect the San Fernando Valley and the Westside, scheduled to open by 2033-35. Approximately $3.8 billion is allocated to extend that service from the Westside to LAX with a 2057-59 opening date.

Complementary Efforts

Under Metro’s 28 by 2028 initiative, the Valley-Westside portion of the project is identified as a candidate for potentially accelerated completion by the 2028 Olympic and Paralympic Games in Los Angeles (LA 2028).

Measure M also provides $260 million for ExpressLanes on the I-405 between the US 101 and I-10. This corridor is identified as a priority in Metro’s Countywide ExpressLanes Strategic Plan.
