Ridge Route Alternate Presentation

Leave a comment

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!

Highway 99 Update

Leave a comment

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.

1914 Parker Truss Salinas River Bridge (49-0109)

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.

To commemorate the 50th anniversary of the February 9, 1971 M6.6 Sylmar / San Fernando Earthquake, our featured image shows the construction work in progress on the I-5 and State 14 interchange in 1970. This work would be halted abruptly in the early hours of February 9, 1971. After this, it would be reconstructed two more times. The earthquake changed the way freeways such as this were built and did further seismic codes throughout the state.
