San Pedro via Dominguez was a 25.39-mile (40.86 km) interurban transport route, part of the Pacific Electric system in Greater Los Angeles.

A ship strike in 1955 necessitated removal of the drawbridge, and trains were rerouted back on the West Basin Line.

At this location, the dual tracks veered away from the Southern Pacific Tracks (and Alameda Street) southwesterly toward Wilmington, crossing a Santa Fe Branch Line and Pacific Coast Highway to reach Flint Junction, where the Long Beach–San Pedro Line joined from the east.

From Flint Junction, the dual tracks continued southwesterly into Wilmington, crossing Anaheim Street, where the Catalina Dock Line branched off to the south.

The dual tracks continued southerly four blocks to the terminus of the line at the San Pedro Pacific Electric on 5th Street.

[1] The Waterfront Red Car was a partial restoration of the southern end of the route, intended to provide transportation in the San Pedro Harbor area.

The operation ran primarily on weekends from 2003 to 2015, when service was "temporarily" suspended due to nearby road construction.
