This photo shows the I-10 / I-215 interchange in San Bernardino, California as it existed in 1958. At the time, those numbers didn’t quite exist. Back then, this was the junction of US 70, US 91, US 99, US 395, and State 18. The view is looking south along what is now I-215 with the Santa Ana River bridges in the foreground. The bridge to the left was US 99 until the 1930’s. The two bridges to the right are still around, though widened.
Today, the Historic Highway 99 Association of California with the City of Calexico, posted new Historic Route signs at the south end of old US 99. Come see the photos!
On Tuesday, April 6 at 6pm, I will be giving a presentation via Zoom on the Ridge Route Alternate section of US 99 during the regular monthly meeting of the Historic Highway 99 Association of California. It will cover the history of the roadway from its original construction through to its replacement by I-5 from Castaic to Tejon Pass. The presentation will include some rarer photos of the route and have time at the end for questions. Come join us and learn a bit about the history of US 99 in Southern California!

Big news for the Historic Highway 99 Association of California! They are getting ready to complete their first project, replacing the old and faded signs in Calexico at the south end of US 99. It is a small project but one worth the effort and a great step forward.
Five miles east of Santa Margarita, State 58 crosses the Salinas River. Until 1996, the highway crossed via this 1914 Parker truss span. From 1934 to 1964, the bridge was crossed by State 178, which became State 58 in 1964. The approach to the old bridge included two sharp curves at either end, which the new concrete bridge (49-0237) and alignment eliminated. Today, it is closed to motor vehicle traffic and marked as a Historic Bridge. The new bridge is to the north of this at SLO-58-R4.8.
