Residents and artists in San Diego's Logan Heights have started a mural project to revitalize freeway underpasses. The initiative transforms areas under Interstate 5 and State Route 15 into tributes to local Indigenous and Latino heritage.
A four-year roadmap funded by the Clean California Initiative
The transformation of the Logan Heights freeway underpasses is not a sudden impulse but the result of a four-year development process. According to the report,the Logan Heights Community Development Corporation spent this time consulting with local residents to ensure the artwork accurately reflected the neighborhood's identity. This long-term planning was essential to secure the necssary government approvals and funding through a state Clean California Initiative grant.
The project operates as a public-private partnership, with the California Department of Transportation, the city of San Diego, and the San Diego Association of Governments serving as key government partners. By leveraging these institutional ties, the Logan Heights Community Development Corporation has moved the project from a conceptual design to a physical reality that targets areas previously defined by litter and graffiti.
From Kumeyaay roots to an aspirational spaceship
The murals are designed as a chronological narrative of the region, beginning with the Kumeyaay people to acknowledge the Indigenous history of the San Diego area. The imagery then transitions into the Latino cultural traditions that define the current character of Logan Heights, ending with a futuristic depiction of a spaceship. This progression is intended to frame the neighborhood as a place of growth and imagination rather than just a transit corridor.
This approach reflects a broader urban planning trend known as "placemaking," where neglected infrastructure is repurposed to foster community pride and social cohesion. By turning the underpasses near Imperial Avenue into a gallery of local history, the project attempts to reclaim space that had been surrendered to urban decay, effectively using visual storytelling to signal that the area is valued and watched over.
Polytab installations versus direct pillar painting
The technical execution of the projecct varies depending on the location. As the report says, the artwork for the Interstate 5 underpass is being created on a flexible material called polytab, which will be attached to the structure using specialized adhesives and durable finishes. In contrast, the murals for State Route 15 will be painted directly onto the freeway pillars by professional artists.
Organizers expect the entire installation process to take approximately six weeks. This hybrid approach—combining pre-fabricated panels with direct painting—allows for a mix of community-led contributions and professional-grade execution, ensuring the murals can withstand the harsh environment of a freeway underpass while still incorporating the handiwork of local residents.
What the 75 volunteers and Shepherds Coffee Co. signal for Logan Heights
The project's launch event saw about 75 community members, including ten-year-old Lily May Heines, participating in the painting process. the event was supported by local businesses like Shepherds Coffee Co., which provided free refreshments, and cultural groups such as the Aztec dance group Calpulli Mexihca. This level of grassroots involvement suggests a strong local appetite for cultural reinvestment in the Sherman Heights and Stockton areas.
However, several questions remain regarding the long-term viability of the project. While the use of "durable finishes" is mentioned, the report does not specify who will be responsible for the ongoing maintenance of the murals or how the city plans to prevent the return of graffiti. Furthermore, it remains unclear if the Clean California Initiative grant includes a budget for future repairs or if the Logan Heights Community Development Corporation will need to seek new funding to keep the art pristine.
