Sign up for updates

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. 


Current Status:

Nine new miles of Carpool/HOV Lanes have been completed on I-5 from Lomas Santa Fe Drive to Palomar Airport Road. Additional community enhancements and improvements can be viewed under Project Highlights

Additional construction has begun on the final phase of Build NCC. This work will extend one Carpool/HOV Lane in each direction on I-5 from Palomar Airport Road in the City of Carlsbad to State Route 78 (SR 78) in the City of Oceanside creating 4 new miles of HOV lanes. This segment also includes community enhancements like the Chestnut Avenue Intersection. Carpool/HOV construction will be complete in 2023, and community enhancements will be completed in 2024.


Questions? Call our construction hotline at (844) NCC-0050 or email us at [email protected].

CONSTRUCTION ALERT  #1

Caltrans and SANDAG Build NCC are piloting the use of temporary orange contrast striping in Carlsbad from Palomar Airport Road to SR 78. The new striping aims to alert drivers to the work zone and reduced speed limit while enhancing safety for construction crews and motorists. The orange striping will be removed upon completion of construction in 2023. Please remember to stay alert in Build NCC construction zones and drive 55mph within the project limits. Learn more by reading the Frequently Asked Questions Document, and the Carlsbad Carpool/HOV Project Fact Sheet.

CONSTRUCTION ALERT  #2

Caltrans and SANDAG Build NCC crews work on the highway throughout all hours of the day and night. Please stay alert for the increased presence of construction crews throughout nighttime working hours from 9 p.m. to 5 a.m.

Remember to drive 55 mph throughout Build NCC construction zones to protect yourself and Build NCC crews.  



DRIVE 55

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 State Route 78 (SR 78) in the City of Oceanside – 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 2023.

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.
