Reconnecting San Diego

Our vision is to heal the divide created by Interstate 5, reconnecting neighborhoods and communities through innovative infrastructure solutions that create new public spaces and restore the urban fabric of our city.

Our Vision for Connection

We envision a San Diego where Interstate 5 no longer divides but connects—where innovative infrastructure solutions create new opportunities for community, recreation, and economic growth while addressing the environmental and social impacts of urban highways.

Innovative Solutions

Freeway Lids: Creating Parks Above Traffic

Freeway lids are engineered structures that cover sections of highway, creating new developable land above. These innovative solutions transform unused airspace into vibrant public spaces, parks, and community amenities.

Local Success: Teralta Park

Bridging Communities in San Diego

Right here in San Diego, Teralta Park demonstrates how thoughtful infrastructure can reconnect divided communities. This park was built over I-15 freeway, creating a bridge between the Corridor and Teralta West that were previously separated by the freeway.

Learning from Success Stories

Throughout the nation and the world, communities are engaged in similar efforts. Perhaps the best California example is "Hollywood Central Park" covering US 101 with a 38-acre deck park currently progressing through Environmental Impact Review (EIR) and the planning approval process.

Community engagement and collaborative planning

Public-private partnerships for funding and implementation

Phased approach to development and construction

Advocacy and education to build broad-based support
