Rosecrans Ave / Canon St / Catalina Blvd
Ran from I-8 at I-5 to Cabrillo National Monument in San Diego
This highway may have carried the last western section of former US 80 for a few years. Mostly a busy city street, after passing into the Point Loma Naval Base, the road offers scenic vistas of the San Diego area and Coronado. It was decommissioned in the early 2000’s though signage remained until around 2014 in many places, including I-5 and I-8.
