I‑5/SR‑78 interchange redesign moves forward
Caltrans has formally started the environmental review for a major redesign of the I‑5/SR‑78 interchange in Oceanside.
The project aims to address long‑standing congestion caused by a signalized intersection connecting two major highways, a design that no longer fits modern traffic volumes. While improvements have been discussed for years, this marks the official start of the state‑required environmental and public input phase.
What issues should Caltrans prioritize most at this interchange?
