In early June, Caltrans and SANDAG construction crews will break ground on the final stretch of Interstate 5 (I-5) improvements as part of the Build NCC program. The Build NCC program is the first phase of construction in the North Coast Corridor Program, a 40-year, $6 billion package of highway, rail, bike and pedestrian, environmental protection, and coastal access improvements in San Diego.

These improvements will focus on extending a new Carpool/High Occupancy Vehicle (HOV) Lane, one in each direction, between Palomar Airport Road and State Route 78 (SR 78). These new Carpool/HOV Lanes will connect with the lanes currently under construction in south Carlsbad and Encinitas, as well as the existing Carpool/HOV Lanes that begin in Sorrento Valley.

Upon completion of the extended Carpool/ HOV Lanes in 2022, commuters and residents will be able to travel approximately 23 miles in continuous Carpool/HOV lanes between San Diego and Oceanside. This construction project will also include new auxiliary lanes, sound walls, and bike and pedestrian improvements throughout several Carlsbad interchanges.

During construction, the public can expect to see temporary concrete barriers placed to protect workers and the traveling public, median vegetation removal, narrowed travel lanes, noise, dust, and heavy equipment. The final phase of construction will also employ new orange freeway lane striping, a technique designed to improve traveler and worker safety and increase construction work zone awareness. Additionally, to ensure safety for both motorists and the construction crews, the 55 MPH reduced speed limit will be enforced.
