I-5 Locally Preferred Alternative identified I-5 Express Lanes

Caltrans and the Federal Highway Administration (FHWA) recently identified the Express Lanes Only option as the Locally Preferred Alternative (LPA) for the I-5 Express Lanes Project. The project will add two Express Lanes to the highway in each direction between La Jolla Village Drive in San Diego and Harbor Drive in Oceanside, separated from the existing general purpose lanes by a striped buffer.

“When combined with the rail and environmental improvements planned along the corridor, the Express Lanes Only Alternative offers the appropriate balance of benefits and costs to the environment and community,” said Caltrans’ I-5 Corridor Director Allan Kosup.  “This alternative will improve the quality of life for I-5 travelers by offering new transportation solutions for the future and help to reduce travel times and congestion on the highway,”

After extensive public input, Caltrans and the FHWA determined that the LPA best meets the purpose and need of the project; has the smallest footprint and fewest impacts to natural resources; requires the fewest property relocations; and has the lowest construction costs (estimated at $3.5 billion).
The new Express Lanes will accommodate carpools, vanpools, buses, and single occupancy vehicles using FasTrak®. The lanes also will ensure reliable travel times along the corridor and improve the movement of goods and services on the I-5 and beyond.

The I-5 Express Lanes Project is part of a comprehensive program of highway, rail, environmental, and mobility enhancements along the North Coast Corridor (NCC) that are being funded by TransNet. The North Coast Corridor stretches 27 miles along San Diego’s coastline, crosses six lagoons, and connects the cities of Oceanside, Carlsbad, Encinitas, Solana Beach, Del Mar, and San Diego. 

The NCC Program is composed of three primary focus areas – the I-5 Express Lanes Project, coastal rail and transit enhancements, and environmental protection and coast access improvements. Improvements proposed for the NCC represent several billion dollars in investment for the San Diego economy over the next few decades.
