The North Coast Corridor (NCC) Program offers a balanced transportation system to provide travelers choices for the future while enhancing the quality of life for residents. The NCC Program is comprised of three primary focus areas – the I-5 Express lanes project, coastal rail and transit enhancements, and environmental protection and coastal access improvements.

Highway Improvements
As part of the NCC Program, several highway improvements are planned to be implemented through a phased approach over the next 30 years. The improvement projects include:

I-5 Express Lanes Project

I-5 Express Lanes Project
Adds two Express Lanes in each direction on Interstate 5 from La Jolla Village Drive in San Diego to Harbor Drive in Oceanside. The project will ensure a reliable, congestion-free travel option throughout the corridor.

I-5/Genesee Avenue Interchange project

I-5/Genesee Avenue Interchange Project
Includes the replacement of the existing overcrossing, widening of freeway access ramps, and the addition of an auxiliary lane in the northbound direction on I-5 between Genesee Avenue and Roselle Street. Additionally, the project will add a new, separated bicycle/pedestrian path, providing links to transportation, employment centers, hospitals and University of California, San Diego.

I-5/56 Interchange Project

I-5/56 Interchange Project
Proposes to improve the traffic operations on I-5 between Del Mar Heights Road and Carmel Valley Road, and on SR 56 between I-5 and Carmel Country Road.

I-805 HOV/Carroll Canyon Road Extension project

I-805 HOV/Carroll Canyon Road Extension Project
Includes the extension of Carroll Canyon Road under I-805, construction of two miles of High Occupancy Vehicle (HOV) lanes in each direction along I-805 from I-5 to Carroll Canyon Road, and construction of a northerly Direct Access Ramp (DAR) from the Carroll Canyon Road Extension to the HOV lanes.
