Shortly after construction
The bridge was built as a wooden trestle. Water is still flowing in the Alamo River from the Colorado and filling the Salton Sea. The river only predates the bridge by a few years.

The center truss is hard to pick out here.

Central span
The central span is easy to overlook since it blends in with the wooden beams. Note the two supports in the center - there is a couple of inches between the supports and the bridge, so they were probably "temporary" but never removed.
