Significance: The Henry Ford Bridge (Badger Avenue Bridge) is one of only two surviving Strauss double-leaf bascule railroad bridges in North America. It was an important transportation link in the Los Angeles-Long Beach Harbor, which in 1923 was beginning its growth into one of the world's key port facilities. The designer of the bridge, Joseph Strauss, was also the designer of the Golden Gate Bridge in San Francisco, California.

25. Central tension lock looking straight down, south span is to the left, north span to the right. there are three tension locks just below road level.
26. Central compression lock, north span facing north. Compression lock locks two spans together at highest point. There are three compression locks.
27. 'Frogs' which match up the rail lines on the tower and the movable span as the bridge closes. North span facing south.
28. View of the electrical and mechanical rail connections between the two spans. View is from the south span looking north at the north span which is not fully down.
29. View of the electrical and mechanical rail connections between the two spans facing north. Both spans are down and locked. These connections are operated from the interlocking machine in the control house (photo 42).
30. Closeup view of the electrical and mechanical rail connections between the two spans facing north; interlocking mechanism with controller. Both spans are down and locked.
31. Closeup view of the electrical and mechanical rail connections between the two spans facing north; 'pins' and electrical connection. Both spans are down and locked.

33. Three bolts on railing outside control house on north tower, one bolt on first handrail post of the north span (bridge is in the open position). As the bridge opens or closes the single bolt on the handrail post moves past the three stationary bolts. This system is used by the bridge operator to judge speed and position of the north span as it opens or closes. Based on these bolts movement of the north span is speeded up or slowed down and the brakes applied during the opening and closing process. View facing east.
34. Two lights on the western concrete counterweight on the south span. The two lights are used, in conjunction with visible guides on Terminal Island by the bridge operator to judge speed and position of the south span as it opens or closes. Based on the movement of the lights relative to each other and the background the south span is speeded up or slowed down and the brakes applied during the opening and closing process. View facing south.
