The North Coast Corridor CM/GC project included highway work, railroad double-tracking, and lagoon restoration.
The railroad work consisted of doubletracking four miles of the LOSSAN corridor, the nation’s second busiest intercity rail corridor, supporting Class I commuter, intercity, and freight rail services. The double tracking included reconstructing two major railroad bridges across the coastal lagoons, grade crossing modifications, and signaling and communications work.
The highway portion added 14 miles of HOV lanes on I-5 between Lomas Santa Fe and Highway 78, including replacing highway bridges across two lagoons, new sound walls, retaining walls, surface roadway reconstruction, and site work. Lagoon restoration included dredging, beach restoration, channel improvements, and wetland restoration.

“Sometimes the environment usually ends up on the losing side of big infrastructure projects like this, but nothing could have been further from the truth with your team. We were treated as equal partners in the decision-making process and that is what makes this entire project a model for others to follow.”
Executive Director, San Elijo Lagoon Conservancy
