Meridiam, Partners Supporting Metro’s Sepulveda Transit Corridor Project’s Locally Preferred Alternative

LOS ANGELES – Meridiam together with partners Bechtel and American Triple I (ATI) – collectively known as Sepulveda Transit Corridor Partners (STCP) – 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 — one of the most significant transit investments in the country.

The heavy-rail project will deliver a fast, reliable, and sustainable transit alternative to the I-405/Sepulveda corridor in Los Angeles. Operating at speeds of up to 70 mph, with trains planned to run every 2.5 minutes, the line is anticipated to carry over 100,000 passengers daily, connecting the San Fernando Valley and Westside in under 20 minutes. Leveraging state-of-the-art technology, the fully automated system will enhance safety, efficiency, and operational flexibility, while significantly reducing travel times and transfers.

Seamlessly integrated within existing and future regional transit networks (Metro, Amtrak, and Metrolink), the line will offer convenient single-seat rides and stations strategically located at key destinations, including a stop at the heart of UCLA’s campus along with direct links to major medical centers. Designed for high ridership, the system will be built to accommodate strong peak‑hour demand.

This advanced transit solution draws on STCP’s decades of global collective experience in the delivery and operation of cutting‑edge rail systems, including the Purple Line Light Rail in Maryland, the Doha and Paris metros, London’s Elizabeth line, and the Riyadh Metro.

Beyond transforming regional mobility, the project is poised to generate significant economic benefits. Construction, as well as long-term operations and maintenance, is expected to create thousands of well-paid local jobs and drive sustained economic development across the Los Angeles area. This line would provide a fast, safe, reliable alternative to one of the region’s most heavily travelled and congested corridors.

“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, Meridiam. “On behalf of the STCP partner group, we thank LA Metro for the opportunity to advance our vision in service of the LA community and look forward to our continued collaboration over the coming decades.”

“ATI is pleased to work with LA Metro and our STCP partners to deliver this transformational project to the people of Los Angeles,” says David Cibrian, Managing Partner, ATI. “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.”

“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.

The STCP consortium is comprised of Meridiam, Bechtel, and ATI. Meridiam is a premier investor, developer, and long-term asset manager focused on sustainable infrastructure, with a successful track record of delivering some of the largest public-private partnerships globally. Bechtel is a trusted engineering, construction, and project management partner with expertise in delivering passenger rail systems. ATI is an infrastructure investor, developer, and asset manager with a track record in complex, large format infrastructure projects in the US.

The team is further strengthened by leading engineering and heavy rail specialists Mott MacDonald, T.Y. Lin, Systra, Stadler, and Siemens, along with RATP Dev to support operations and maintenance.
