Caltrans seeks public input on a long-range plan for I-110 from San Pedro to downtown L.A.

The plan is a study that identifies potential improvements for bus, rail, bike and car travel. It does not fund or approve construction.

Caltrans is asking Southern California residents what they want from the I-110 corridor, a major route linking the Port of Los Angeles and the South Bay to downtown, as it updates a long-range plan for the roadway.

What the study covers

Caltrans District 7 is updating the Interstate 110 Comprehensive Multimodal Corridor Plan, or CMCP, according to the project's public input page and Random Lengths News. The study area runs from the State Route 47 interchange near the Port of Los Angeles in San Pedro to the Interstate 5 interchange near downtown, a distance of roughly 20 miles. Caltrans describes the corridor as one of the busiest and most important in the region, used by tens of thousands of travelers a day for commuting, goods movement and longer trips.

Caltrans says the plan aims to address new traffic volumes, climate change and overall corridor updates. It will study current and future conditions and work with partner agencies and local communities, the agency says. Challenges it names include persistent congestion, ongoing safety concerns, and noise and vehicle emissions affecting nearby neighborhoods.

What a corridor plan is, and is not

This is a planning document, not a construction project. Caltrans' District 7 page says the goal of a CMCP is to develop a strategy and a list of potential transportation projects that reduce congestion and greenhouse gas emissions and improve livability. Once projects are identified and documented, the agency says, it helps the district and its partners pursue future funding and move projects toward construction.

Nothing in the Caltrans materials reviewed says a specific lane, rail line or other project has been selected, funded or approved.

What residents were asked

Random Lengths News reported on Oct. 14 that residents could take a survey and share views on ideas such as more dedicated lanes, a rail line down the median, improvements to J Line bus stops, and improvements for people on bikes and in cars. That list is the newspaper's description of the survey. The Caltrans pages reviewed do not list specific projects.

The project's public input page lists a first-round virtual workshop on Aug. 18, a second-round in-person workshop on Sept. 23 at the Nakaoka Community Center in Gardena, and a pop-up at CicLAvia on June 28. Caltrans' District 7 page says surveys on the I-110 and several other corridors have recently been completed and invites additional comments at D7.System.Planning@dot.ca.gov.

The timeline

According to the project page, data collection and analysis is planned for summer and fall 2026, workshops run from summer through winter 2026, a draft plan is planned for winter 2026, and a final plan for spring 2027.

Why it matters

Caltrans says the corridor connects South Bay and Harbor Gateway communities to downtown and supports goods movement as well as commuting. Corridor plans can shape which projects the state and its partners pursue for funding in later years, so early input can influence what ends up on the list.

What's next

  • Winter 2026: Caltrans plans to release a draft plan.
  • Spring 2027: a final plan is planned.
