North Coast Corridor / I-5 Improvements

Build NCC Highway Improvements

As part of the integrated approach of Build North Coast Corridor (NCC), several improvements to the Interstate 5 (I-5) corridor will be implemented between 2017 and 2021.  The improvements include the extension of carpool lanes, replacing and lengthening the San Elijo Lagoon highway bridge, new sound walls on some private property, a new Park & Ride/Multi-Use Facility at the I-5/Manchester Avenue interchange, and construction of auxiliary lanes along the I-5.

Build NCC is the fist phase of construction of the NCC Program in the cities of Solana Beach, Encinitas, and Carlsbad.  Build NCC is part of a 40-year vision to improve the quality of llife for residents, create a stronger local and regional economy, and enhance the coastal environment.

HOV/Carpool Lanes and Sound Walls:
Caltrans will construct carpool lanes on I-5, one in each direction, from Lomas Santa Fe Drive in Solana Beach to State Route 78 (SR 78) in Oceanside.  Also included in the HOV/carpool lanes project is the construction of sound walls on private property in the cities of Encinitas and Carlsbad. 

San Elijo Lagoon Highway Bridge Replacement:
To accommodate the new carpool lanes along I-5, the San Elijo Lagoon highway bridge will be replaced.  The bridge will also improve tidal flow and the overall health of the lagoon.  In addition, Caltrans will divert highway runoff in to natural treatment features such as bioswales and detention basins to help prevent runoff from entering the lagoon.

Park & Ride/Multi-Use Facility:
A Park & Ride/Multi-Use Facility will be constructed at the I-5/Manchester Avenue interchange and serve as the primary San Elijo Lagoon access point.  The versatile facility will provide parking for carpools/vanpools and include bike lockers, electric vehicle charging stations, and recreational access to the San Elijo Lagoon and the new North Coast Bike Trail.
