I-805 South Pavement Rehabilitation and Asset Management Project

Project Overview

The I-805 South Pavement Rehabilitation and Asset Management Project will improve pavement conditions and upgrade infrastructure along a 14.5-mile stretch of Interstate 805 in the cities of San Diego, Chula Vista, and National City from the San Ysidro Port of Entry to SR-15. This important effort is focused on preserving existing infrastructure, improving safety, and modernizing the corridor to meet current and future transportation needs.

The project will rehabilitate pavement along the main roadway, shoulders, and freeway ramps to extend the life of the existing highway. Beyond resurfacing, the project incorporates a broad range of upgrades to improve performance, safety, and environmental conservation.

This map shows the limits of the project. For more information, call (619) 688-6670 or email CT.Public.Information.D11@dot.ca.gov

Goals

  • Long-Term Efficiency by extending pavement life through resurfacing and rehabilitation, reducing the need for major future repairs.
  • Focus on fiscal conservation by maintaining and improving existing infrastructure instead of costly replacements.
  • Enhancing Safety by improving traffic flow with updated traffic management systems and operational upgrades to increase accessibility for all travelers.

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. During construction temporary freeway closures will be required to remove and install overhead signs in both directions. Detours will be in place to reduce impacts on motorist.

Project Features

The I-805 South Pavement Rehabilitation and Asset Management Project work will include:

  • Pavement grinding, complete lane replacement, and slab rehabilitation
  • Repair and upgrade ramps and shoulders
  • Installation and repair of culvert (drainage systems)
  • Replace overhead and roadside signs
  • Upgraded safety features like Midwest guardrail systems
  • Slope paving and paving in narrow and hard-to-access areas
  • Upgrading non-standard curb ramps to meet accessibility ADA standards
  • Installing and upgrading Intelligent Transportation Systems (ITS)
  • Adding three auxiliary lanes to improve traffic flow
  • Constructing a new bike trail and adding Class II, III, and IV bike lanes
  • Bridge widening and retaining wall installation
  • Ramp meter mast arms installation
  • Falsework removal for slab replacement

Project Benefits

  • Upgraded Safety: Rehabilitating pavement, upgrading guardrails and improving signage to enhance driver and pedestrian safety.
  • Improved Traffic Flow: New auxiliary lanes will ease congestion and reduce travel times.
  • Enhanced Accessibility: Upgraded curb ramps and pedestrian paths make the corridor more accessible.
  • Modernized Infrastructure: Intelligent transportation systems will improve traffic management responsiveness.
  • Active Transportation: New bike lanes and trails designed to encourage cycling and multimodal commuting.
  • Long Term Investment: Preventative highway maintenance reduces the need for frequent repairs and emergency fixes.

Project Status

Construction begins November 2025 with an estimated completion by Spring 2030.

Project Cost

$222.5 is solely funded by the State Highway Operation and Protection Program with $197.3 million in Federal funds and $25.1 million in SB1 Funds.
