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.

This was the original alignment and lasted until the 1940’s when this section was upgraded to an expressway on a new alignment. In January 1922, construction …
US 99 parallels the Southern Pacific Railroad for a significant portion of its journey across the Great Central Valley. At times, it has to cross those tracks. Many of those crossings were the site of collisions, mostly by people trying to beat the train. They also slowed traffic down quite a bit. In a statewide effort to reduce problems at grade crossings, the State built grade-separations at these locations.
At Famoso, north of Bakersfield, an underpass was built in 1936, which eliminated one of the busier crossing. That structure was eventually replaced by an overpass in 1970. Today, the original crossing partially remains, with paving leading from the freeway to the railroad. The last time a car traversed this paving may well have been over 70 years ago.
