LOSSAN Rail Realignment

Alongside the short-term bluffs stabilization project, we are studying potential options for a long-term solution. The ultimate goal is to move the rail line off the bluffs in the City of Del Mar.

We will assess current conditions, such as safety and speed capabilities, and identify opportunities to improve travel times and add future capacity.

Senate President Pro Tem Toni Atkins secured $300 million in the state budget to move this study through the environmental and design phase—a huge step forward for a critically-important regional project. With the state funding we’ve received, we are working closely with our partners along the entire corridor to identify potential federal funding opportunities to help complete this project as soon as possible.

We are beginning the preliminary engineering and environmental phase for the SD LOSSAN Rail Realignment and are working towards a final environmental document in 2026. Public outreach and community engagement for this project began in 2020 and is anticipated to ramp up in late 2023 through 2026.

Multi-colored lines depicting various potential railway alignments and tunnel openings that have been studied thus far. The lines stretch from the San Dieguito Lagoon to the north, the Los Penasquitos Lagoon to the south, the Del Mar Bluffs to the west, and the I-5 to the east.
