Build NCC

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:

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.

SURVEY ALERT 

Temporary Orange Contrast Striping Pilot Program Feedback Survey 

Caltrans and SANDAG Build NCC would like to notify you of a survey to gather feedback on the temporary orange contrast striping within the active construction zones on Interstate 5 (I-5) between Palomar Airport Road in the City of Carlsbad and State Route 78 (SR 78).  

You can view the survey here.   

Survey completion takes approximately 3 minutes. We thank you in advance for helping improve safety along the North Coast Corridor.  

Temporary orange contrast striping is used in construction zones to increase the contrast when traditional white lane striping is removed during construction staging.  The orange striping is intended to increase awareness of the work zone and enhance safety for motorists and construction workers. Your feedback will help us gather the necessary information on the success rate of this project. Safety is of the utmost importance to the Caltrans and SANDAG Build NCC team


NOTIFICACIÓN DE ENCUESTA 

Encuesta sobre el programa piloto de las rayas de delimitación temporales de color naranja con contraste 

Build NCC de Caltrans y SANDAG desea notificarle de una encuesta que hemos lanzado para recopilar sus comentarios sobre el uso de las rayas de delimitación temporales de color naranja con contraste en la zona de trabajo activa de la Interestatal 5 (I-5), entre Palomar Airport Road en la Ciudad de Carlsbad y la Ruta Estatal 78 (SR 78).  

Puede encontrar la encuesta aquí.   

Responder la encuesta toma aproximadamente 4 minutos. Gracias de antemano por ayudarnos a mejorar la seguridad a lo largo del Corredor de la Costa Norte.  

Las rayas de delimitación temporales de color naranja con contraste se usan en las zonas en construcción para aumentar el contraste cuando se remueven las rayas de delimitación tradicionales de color blanco de los carriles en la etapa de preparación para la construcción. La intención de las rayas de delimitación de color naranja es aumentar la visibilidad de la zona de trabajo y mejorar la seguridad de los conductores y de los trabajadores de la construcción. Sus comentarios nos ayudarán a recopilar información necesaria sobre el éxito de este proyecto. La seguridad es de suma importancia para el equipo Build NCC de Caltrans y SANDAG.  



CONSTRUCTION ALERT  #1

Northbound I-5 Closure: Carlsbad Village Drive to SR 78 Caltrans and SANDAG Build NCC crews will conduct a planned Interstate 5 (I-5) closure along northbound I-5 from Carlsbad Village Drive to SR 78 in the City of Carlsbad. This closure will allow crews to temporarily relocate overhead sign structures from the median to the outside shoulder.
The closure will begin Tuesday, May 24, at 10 p.m. and will reopen at 5 a.m. on Wednesday, May 25. All northbound traffic must exit at Carlsbad Village Drive and can re-enter northbound I-5 through SR 78. Detour signage will be in place to guide motorists around this closure. Motorists will detour using El Camino Real to SR 78.
Please see the detour map below:

Nearby residents and businesses can expect nighttime construction noise and lights, including Occupational Safety and Health Administration (OSHA) required vehicle back-up alarms. Crews will work to minimize noise and impacts to all nearby communities, and motorists will be detoured with signage and traffic controls. Check back here to receive up-to-date weekend ramp closure notifications and detour routes. To receive construction updates by text message, text “BuildNCC” to (760) 454-0077.  

CONSTRUCTION ALERT  #2

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  #3

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.
