I-5 Asset Management Project in San Diego: $114 Million Pavement Rehab Effort Presses On

Interstate 5 serves as San Diego County's lifeline, carrying hundreds of thousands of vehicles daily from the border to North County. Right now, a major preservation initiative—the I-5 Asset Management Project—is underway to extend the freeway's lifespan without full replacements. With weekend closures making headlines in November 2025, this roughly $114 million effort (often rounded to $100M+ in coverage) focuses on pavement rehabilitation across a vast southern segment. At Cali Dream Construction, we track these roadway upgrades because smoother infrastructure supports everything from daily commutes to heavy-haul projects. Here's the objective breakdown, including agencies, scope, funding, and timelines.

Project Overview and Goals

The I-5 Asset Management Project targets long-term maintenance reduction on one of California's busiest corridors.

• Primary Focus: Rehabilitate pavement on main roadways, shoulders, and ramps to improve ride quality and extend service life.
• Coverage Area: Spans approximately 27 miles through the cities of San Diego, Chula Vista, National City, and up to 0.3 miles south of Via De La Valle (near Del Mar/Solana Beach border). Starts at Camino De La Plaza near the international border.
• Key Benefits: Reduces future repair needs, enhances safety through better traffic flow, and incorporates updated traffic management systems.

This "fix it first" approach prioritizes preserving existing assets over expansion, aligning with statewide strategies for sustainable infrastructure.

Total Cost and Funding Sources

The project carries a price tag of $113,745,800 (commonly reported as $114 million or rounded to $100M+).

• Federal Contribution: $102,618,300 from the State Highway Operation Protection Program (SHOPP).
• State Contribution: $11,127,500 from SB1 (Road Repair and Accountability Act) funds.

It's one piece of a broader $623 million Caltrans investment across I-5, I-805, and SR-78 in San Diego County, plus part of $1.6 billion in ongoing countywide work.

Lead Agency and Key Players

• Lead Agency: California Department of Transportation (Caltrans) District 11.
• No Direct SANDAG Involvement Noted: Unlike North Coast Corridor projects, this falls under Caltrans' direct oversight for asset management.

Caltrans handles planning, execution, and public notifications, including detour coordination during closures.

Construction Timeline and Progress

Work kicked off earlier in 2025, with phased implementation to minimize disruptions—though full weekend closures are required for major paving segments.

• Start Date: Spring/Summer 2025 (part of the $623M package announced in May 2025).
• Ongoing Activities: Pavement grinding, repaving, ramp upgrades, and shoulder improvements.
• Expected Completion: Phased through 2027, with major segments wrapping by late 2026 or early 2027 (tied to the larger $623M initiative).

As of November 14, 2025, the project is actively advancing, with recent and upcoming full closures highlighting progress.

Recent and Upcoming Closures: What Drivers Need to Know

To accelerate work, Caltrans schedules 55-hour weekend shutdowns—closing all lanes in one direction while keeping the opposite open when possible.

Notable 2025 closures include:

• September 5-8: Southbound I-5 from SR-52 to Mission Bay Drive.
• September 26-29: Northbound I-5 from I-8 to Mission Bay Drive.
• October (various weekends): Northbound along Mission Bay area.
• November 7-10: Southbound from SR-52 to Mission Bay Drive (9 p.m. Friday to 5 a.m. Monday).

These allow crews to complete large paving sections safely. Detours typically route traffic via I-805 or local arterials. For real-time alerts, follow @SDCaltrans on X or visit the Caltrans QuickMap at quickmap.dot.ca.gov.

Broader Context in San Diego's Infrastructure Pipeline

This project complements other I-5 efforts, like the North Coast Corridor (SANDAG/Caltrans collaboration wrapping major phases by end of 2025) and rail improvements. It addresses decades of wear on sections built in the 1960s-1970s, ensuring the freeway handles growing demands from commuters, freight, and tourism.
