First Phase of I-805 South Project

Construction on the First Phase of I-805 South Project to Begin Week of June 18

Project to Enhance Transit and Carpool Opportunities in South San Diego County

Work is scheduled to begin next week on the first phase of the Interstate 805 (I-805) South Project, a $1.4 billion effort to create a modern, new transportation backbone that will meet the future needs of travelers in our region.

Work includes building one High Occupancy Vehicle (HOV), or carpool lane, in each direction along an eight-mile segment stretching from East Palomar Street in Chula Vista to State Route 94 (SR 94) in San Diego. Carpools, vanpools, motorcycles and permitted clean air vehicles will be able to utilize the HOV lanes, which are scheduled to
open in fall 2013.

Phase 1 also includes the construction of a Direct Access Ramp (DAR) and a Transit Station and Park & Ride at East Palomar Street in Chula Vista. Additionally, sound walls will be constructed along the route to help reduce freeway noise and enhance the quality of life for neighboring communities. Phase 1 is scheduled to be completed in 2014.

During construction, you can expect to see temporary freeway lane and ramp closures, detours, reduced shoulders and lane widths, work along the freeway median, the installation of temporary concrete safety barriers, temporary lane restriping, construction equipment and signage. Motorists are urged to slow down during construction. Not only
is it required by law, but it helps save lives. Additionally, travelers are encouraged to give themselves more time and anticipate possible traffic delays.

The second phase of the I-805 South Project will further increase transportation choices by expanding the HOV lanes into Express Lanes for a total of four lanes, two in each direction. The Express Lanes will serve the planned South Bay Bus Rapid Transit project, carpools, vanpools, buses, motorcycles, permitted clean air vehicles and solo drivers using FasTrak®. Phase 2 also includes the addition of in-line transit stations built in the freeway center median and freeway-to-freeway direct connectors. Work on the second phase of the project is scheduled to begin in 2015 and be completed in 2020.

A construction workshop will also be held on Tuesday, July 17 from 6 p.m. to 8 p.m. at Hilltop High School, 555 Claire Ave., in Chula Vista. At the workshop, members of the community will have the opportunity to learn about our progress and plans and ask team members questions about the construction process.

In an effort to keep the community informed, Caltrans will provide regular updates on construction hours, closures and detours through signage, notices and web postings at A construction hotline has also been established at (888) 941-5005.
