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.
