The Pacific Electric Railroad Bridge or Southern Pacific Railroad Bridge is a historic railroad bridge in Torrance, California USA. It spans across Torrance Boulevard at Bow Street, a short distance west of Western Avenue. It was once part of the north/south Torrance to San Pedro spur line of the Pacific Electric Railway. The line was the railroad's first interurban line to San Pedro. After splitting off to the east from the Union Tool Company plant which was once a short distance south of the bridge, the line ended at a Columbia Steel steel mill (later United States Steel) by running up and over the east/west Torrance local line. It is the only part of the PE which crossed itself this way. This was due to the area's geography. If the railroad simply built a spur off of the main line, it would have meant that trains trying to get to the steel mill would have faced too steep a climb. The steel mill has since been torn down to make way for the national headquarters of American Honda Motor Company, but the remaining part of the Torrance line - which once had two separate tracks - was rebuilt in 2003 and is still in use for local train runs by the Union Pacific Railroad. Gone too are the Pacific Electric's Torrance shops at the western branch of the split, now the site of an industrial park and which still receives trains on the local line.
