I-805 North Express Lanes Project

The Interstate 805 (I-805) North Project covers a distance of approximately four miles, from just south of State Route 52 (SR 52) to just north of Mira Mesa Boulevard in San Diego. The project will widen the freeway to accommodate four carpool, or High Occupancy Vehicle (HOV), lanes from SR 52 to La Jolla Village Drive and two carpool lanes from La Jolla Village Drive to just north of Mira Mesa Boulevard.

Additionally, the project will construct a south-facing Direct Access Ramp (DAR) at Carroll Canyon Road to allow carpoolers, vanpools, buses, motorcycles and solo drivers in permitted clean air vehicles to easily access the carpool lanes. The south-facing DAR will connect to the recently-completed (April 2014) north-facing DAR and Carroll Canyon Road extension bridge, which includes a new bike lane to improve travel between Sorrento Valley and Mira Mesa. A DAR will also be constructed at Nobel Drive, which also includes a new Park & Ride lot on the southwest corner of I-805 and Nobel Drive to encourage carpooling and to provide bus transfers from the proposed Bus Rapid Transit facility.

Project plans also include reconfiguring the Governor Drive interchange by relocating the southbound entrance-ramp to the northwest quadrant. This would minimize the conflict with southbound I-805 traffic merging onto SR 52. Lastly, the project includes a direct freeway-to-freeway HOV connector in the median, from westbound SR 52 to northbound I-805 and southbound I-805 to eastbound SR 52.

The project will be constructed in five stages. The contract for Stage 1 was awarded in March 2012 and will be developed as a Design-Build contract. Design efforts are underway and construction started in spring 2013.

New Transportation Choices

The I-805 North Project is an integral part of a modern, new transportation backbone that will meet the future needs of travelers in our region. Since I-805 opened in 1975, vehicle trips on the freeway have increased by 300 percent and are projected to increase in the future. As such, improvements are planned to provide commuters with new transportation options to reduce traffic and travel times along the I-805 corridor.

These improvements include the construction of HOV/ Express Lanes, Direct Access Ramps (DAR)s to provide commuters direct access to the HOV and Express Lanes, and Park and Ride facilities, which will provide commuters with access to a planned Bus Rapid Transit (BRT) System.

Improvements to I-805 will help accommodate the projected population and employment growth in the region by connecting employment and activity centers including offices, shopping, recreational facilities, communities, and schools. Improvements to I-805 also will help maintain and grow the region’s economy, through the enhanced movement of goods and services along a main transportation artery for the region.

Project Funding

The estimated cost of the project is $587 million. Funding is expected to come from a combination of federal, state, and local programs, including TransNet, a half-cent sales tax for transportation projects.

Stage 1 (2013 - 2016)

Stage 1 consists of constructing one carpool lane in each direction, from just north of SR 52 to just north of Mira Mesa Boulevard and the south-facing DAR at Carroll Canyon Road. Bridge modifications at Mira Mesa Boulevard, Carroll Canyon Road, Rose Canyon, and Governor Drive are also part of stage 1. This stage is estimated to cost approximately $86 million.

Stage 1 milestone: On Monday, June 22, 2015, one southbound carpool lane from just south of La Jolla Village Drive to just north of SR 52 opened to traffic. 

Stage 2-4 (2017 - 2020)

Stages 2 through 4 will construct the second carpool lane in the median from just north of SR 52 to just north of La Jolla Village Drive. Because the existing median cannot accommodate the second carpool lane, the outside lanes will be widened. Additionally, the Nobel Drive DAR and the Nobel Drive Park & Ride and Transit Station will be constructed, and the Governor Drive interchange will be reconfigured. These three stages are estimated to cost approximately $411 million.

Stage 5 (2037 - 2040)

Stage 5 will construct a direct freeway to freeway HOV connector in the median, from westbound SR 52 to northbound I-805 and southbound I-805 to eastbound SR 52, which will also accommodate travel in the reverse direction. This final stage is estimated to cost approximately $90 million.
