I-805 South Managed Lanes Conversion Project

High Occupancy Vehicle to High Occupancy Toll

Project Overview

Caltrans, in partnership with the San Diego Association of Governments (SANDAG), seeks to upgrade 8.5 miles of managed lanes from existing High Occupancy Vehicle (HOV) lanes to High Occupancy Toll (HOT) lanes along the southern segment of the I-805 corridor from East Palomar Street to State Route 94. The project limits extend from Olympic Parkway to Landis Street. The Project proposes to incorporate existing technology to support additional modal shift from single-occupancy vehicles (SOVs) to transit and shared-use vehicles. The project scope will include gantries, message boards, a ridership detection system, a variable tolling system, and lane separation buffers. This project will reduce congestion, mitigate vehicle miles traveled, reduce greenhouse gases, and provide an alternative mode of transportation that will fit the proposed regional managed lanes network.

Goals

  • Convert existing managed lanes along I-805 South from HOV to priced HOT lanes to provide system continuity along the I-805 corridor and transit usage
  • Install Intelligent Transportation Systems (ITS) to enforce lane restrictions and support ease of electronic tolling
  • Will increase safety along the corridor through lighting at various locations, including the HOT

What to Expect

Daytime work will be conducted from 6:30 am to 3:30 pm. Intermittent ramp and lane closures will happen in the evening from 9:00 pm to 5:00 am. A few full roadway closures are to be expected in the evenings.

Project Benefits

The Project will enhance safety and quality of life in San Diego’s South Bay communities and for users connecting to residential and employment centers along the United States-Mexico Border and I-805 Corridor. This Project will continue to create a modern, new transportation backbone along the I-805 corridor that will meet the future needs of travelers in our region and enable new opportunities for carpoolers, transit, and other eligible clean air vehicles. When complete, the Project will offer new transportation choices, relieve traffic congestion, and improve the quality of life in San Diego’s South Bay and beyond.

The Project will provide the following benefits:

  • Improve connections along the I-805 Corridor to major residential and employment centers in San Diego, National City, and Chula Vista
  • Enhance roadway operations and safety by reducing incidents of HOV violations, diversions onto local streets, and recurrent congestion
  • Facilitate the expansion of existing and future regional bus rapid transit (BRT), including the existing South Bay Rapid
  • Reinvest toll credits to nearby multimodal projects to support active transportation, transit, and other alternative modes
  • Reduce transportation-related greenhouse gases from idling and recurrent congestion, and incentivize use by eligible clean-air vehicles, carpooling, and transit

Project Status

Construction is expected to begin in 2027, with the target for completion and opening to the public by 2029.

Project Cost

The project is estimated to cost approximately $131 million, including $80.4 million in Federal, $49.6 million in State funds, and $1 million in TransNet funding.
