Build NCC

Highway, rail, environmental, and coastal access improvement projects are underway in the cities of Solana Beach, Encinitas, and Carlsbad 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/High Occupancy Vehicle (HOV) lanes, new bike and pedestrian trails, and the restoration of the San Elijo Lagoon. These highway, rail, and lagoon improvements are being constructed simultaneously to minimize impacts to the lagoon and neighboring communities.

55 MPH ZONE
Motorists traveling along the Build NCC corridor – the
eight-mile stretch of Interstate 5 (I-5) between Manchester Avenue in the City
of Encinitas and Palomar Airport Road in the City of Carlsbad – are advised of
a speed limit reduction to 55 mph in both the north and
southbound directions. The speed limit reduction took effect on March 11, 2019, and will be in place until
project completion in 2022.
The speed limit reduction within the highway work zone is
necessary to ensure the safety of the traveling public, and construction and
public safety professionals as they work to construct the new I-5 Carpool/High Occupancy Vehicle (HOV) lanes.
Construction signage will alert drivers as they enter and exit the construction
zone. Electronic speed feedback signs also will be present to inform the public
of their speed in relation to the reduced speed limit. Additionally, the California
Highway Patrol will be actively working to ensure motorists are driving safely
by enforcing the new, posted speed limit. To learn more about the reduced speed
limit, click here.
