Build NCC

Highway, rail, environmental, and coastal access improvement projects are underway in the cities of Encinitas and Solana Beach as part of Build NCC, the first package of projects being constructed through the 40-year North Coast Corridor (NCC) Program.

Build NCC includes rail double tracking, extended carpool lanes, new bike and pedestrian trails, and the restoration of the San Elijo Lagoon, with the majority of work beginning in Encinitas. These highway, rail, and lagoon improvements are being constructed simultaneously to minimize impacts to the lagoon and neighboring communities. View the San Elijo Lagoon Construction Staging Maps to see how Build NCC will be integrated.
