Harbor Drive Multimodal Corridor Study

Identifying opportunities to improve mobility, safety and quality of life for everyone who lives, works and plays along Harbor Drive and in the surrounding communities.

The Harbor Drive Multimodal Corridor Study identifies potential opportunities to improve mobility and access along the southern portion of Harbor Drive between the Port's two cargo terminals and terminal operations as a well as ways to enhance quality of life for our neighbors who live, work and play along the Port's Working Waterfront and in the surrounding communities.


About the Study

The Harbor Drive Multimodal Corridor Study is a planning study that examined how people use Harbor Drive, address existing issues and challenges, and identify opportunities for improvement. The study focused on the stretch of Harbor Drive between the Port of San Diego’s two cargo terminals, the Tenth Avenue Marine Terminal in San Diego and the National City Marine Terminal, known as San Diego’s Working Waterfront. 

As a 21st Century Port, goals of the study were to identify potential projects that will improve:

  • Community safety, mobility and health;
  • Goods movement;
  • Naval base access and circulation;
  • Shipyard access and parking; and
  • Transit first/last mile access.

The study considered all modes of transportation - pedestrian, bicycle, passenger vehicle, bus, cargo truck, light rail, cargo rail, and vessel. It identified more than 90 large and small improvements, including some that have been previously identified, that range from simple re-striping of a left-turn lane to a much more extensive grade separation project at a trolley crossing.

The study area falls within the jurisdictions of the City of San Diego, the City of National City, the U.S. Navy, the California Department of Transportation (Caltrans), the Metropolitan Transit System (MTS) and the Port of San Diego. These partners are crucial in helping the Port evaluate existing issues, identify potential high-priority projects, and tackle future solutions together. The potential projects could be implemented by the Port and/or these other jurisdictions as funding becomes available over the next 30 years.

Following the evaluation, specific existing improvement projects and new ones were identified. These potential projects could be implemented by the Port and/or other jurisdictions as funding becomes available.
