Sepulveda Transit Corridor Partners (STCP), a consortium led by Bechtel, Meridiam, and American Triple I (ATI), has welcomed the decision by the Los Angeles County Metropolitan Transportation Authority (LA Metro) Board of Directors to select a modified version of its proposal for a high-capacity, fully underground rail line linking the San Fernando Valley to the Westside.
The STCP team also includes Mott MacDonald, TYLin, and Systra, alongside global transit operator RATP Dev. Together, the consortium brings extensive experience in delivering and operating complex urban rail systems worldwide.
The proposed line is expected to serve more than 100,000 daily riders, offering a fast and reliable alternative to the heavily congested I-405 corridor and significantly improving mobility across one of the region’s most travelled routes. Initial operating segment stations would include the Metro G Line, Ventura Boulevard, the University of California, Los Angeles (UCLA), and the Wilshire / Metro D Line.
STCP’s proposal was one of five alternatives subject to extensive public and expert review, including the public circulation of a Draft Environmental Impact Report last year. Following its assessment, LA Metro identified a modified version of STCP’s Alternative 5 as the strongest overall option, citing its potential for meaningful public benefit alongside strong long-term value for taxpayers.
LA Metro will now continue developing the project with the STCP team, drawing on its collective experience delivering major rail programmes such as Maryland’s Purple Line, the Doha, Riyadh, and Paris metro systems, 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,” said Jacob Mumm, General Manager of Bechtel’s Public Infrastructure business.
Mark Campbell, President of Bechtel Enterprises, Bechtel’s project development arm, added: “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.”
“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,” said Nicolas Rubio, CEO Americas at Meridiam.
David Cibrian, Managing Partner at ATI, said: “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.”
The Sepulveda Transit Corridor project is widely seen as one of the most significant transport investments in Southern California, with the potential to reshape travel patterns, support economic growth, and deliver long-term environmental benefits for the region.
