Los Angeles region moves forward with plans for transformational connectivity supported by
internationally recognized, U.S.-based consortium.
LOS ANGELES , Feb. 2, 2026 /PRNewswire/ — Sepulveda Transit Corridor Partners (STCP)—a consortium led by California-founded engineering and construction company Bechtel, global investor, developer, and long-term asset manager Meridiam1, and infrastructure investor, owner, developer, and manager American Triple I (ATI)—welcomes the Los Angeles County Metropolitan Transportation Authority (LA Metro) Board of Directors’ vote to select a modified version of its alternative for a high-capacity, fully underground rail line connecting the San Fernando Valley to the Westside. Additional STCP team members include Mott MacDonald, TYLin, and Systra, along with RATP Dev, a global transit system operator.
The project is expected to serve more than 100,000 daily riders, offering a fast, reliable alternative to the heavily congested I-405 corridor and improving mobility across some of the region’s most traveled corridors. Initial operating segment stations include Metro G Line, Ventura Boulevard, the University of California, Los Angeles, and Wilshire/Metro D Line. The line would provide a fast, safe, reliable alternative to one of the region’s most heavily traveled corridors.
STCP’s alternative was one of five that underwent rigorous public and expert scrutiny, including a public circulation of a Draft Environmental Impact Report last year. LA Metro’s analysis identified a modified version of STCP’s Alternative 5 as the strongest overall option demonstrating both meaningful public impact and strong value for taxpayers for years to come. Next, LA Metro will continue developing the project with STCP’s team, which brings decades of collective experience building and operating some of the world’s most innovative rail systems, including Maryland’s Purple Line, the Doha, Riyadh, and Paris metros, and London’s Elizabeth line.
“We are delighted with this result and look forward to working with LA Metro and the local communities to progress this transformational piece of infrastructure—connecting the Valley with West LA in a more efficient way than ever before.” — Jacob Mumm, General Manager of Bechtel’s Public Infrastructure Business
“As Bechtel’s finance and development group, we are proud that the alternative has been selected and excited to be LA Metro’s partner as we continue developing this innovative solution for the city and county of Los Angeles.” — Mark Campbell, President of Bechtel Enterprises, Bechtel’s project development arm
“In line with Meridiam’s mission to improve people’s lives through essential infrastructure, this project represents a transformative investment in Los Angeles, not only by enhancing mobility but also through new jobs, regional economic development, and environmental benefits.” — Nicolas Rubio, CEO Americas, Meridiam
“ATI is pleased to work with LA Metro and our STCP partners to deliver this transformational project to the people of Los Angeles. This project will serve as a testament to the dedication of all of our partners and stakeholders who brought us to this point and who will continue working together to create jobs, increase mobility, and expand opportunity for all Angelenos.” — David Cibrian, ATI Managing Partner
