history

A section of old US 80 (Wildwood Glen Lane)

I-8 was previously labeled US Highway 80 . The upgrade to the interstate was decided in 1957 and implemented in 1964. The section from Sunset Cliff Boulevard to Rosecrans Avenue was not changed until 1969, as the San Diego Freeway , part of Interstate 5 , was completed at the same time . Before Interstate 8, Rosecrans Avenue was known as California State Route 209 .
