At the south end of SR 103, the Terminal Island Freeway runs south with SR 47 over the Commodore Schuyler F. Heim Bridge to its end at Ocean Boulevard on Terminal Island, at the former Long Beach Naval Shipyard.

Terminator 2: Judgment Day, Mr. & Mrs. Smith, and The Fast and the Furious were three movies that used it for location purposes.

[citation needed] The state route begins at Interstate 710 in Long Beach as a concurrency with SR 47.

The entire Terminal Island Freeway was once part of State Route 47, and was to continue north to Interstate 10 near downtown Los Angeles.

[2] Except where prefixed with a letter, postmiles were measured on the road as it was in 1964, based on the alignment that existed at the time, and do not necessarily reflect current mileage.
