North Coast Corridor (NCC) Route Map, Cost & Status 2026
The North Coast Corridor (NCC) program is a multi-modal transportation initiative spanning 27.0 miles from La Jolla, San Diego to Oceanside, California, officially known as the north coast corridor (ncc). Managed jointly by Caltrans and SANDAG, this long-term infrastructure investment focuses on upgrading the highway and regional rail right-of-way along Interstate 5 and the LOSSAN rail line. Financing relies on a blended funding model combining San Diego's TransNet local sales tax, California state grants, and federal support. Official plans detail comprehensive highway, rail, environmental, and coastal access improvements across northern San Diego County districts. Following extensive environmental review processes and community consultations, the project incorporates Express Lanes, double-tracking rail lines, active transportation paths, and coastal lagoon restorations. Navigating the strategic alignment, the corridor serves as a critical economic artery connecting coastal San Diego to broader regional transit networks. Detailed route map publications outline progressive infrastructure phases targeting an ultimate completion date of 2050.
Project information is compiled from official agency documents, federal records, environmental reviews, and verified public announcements.
