The date for this bridge seems to have been a discussion in the past. I have done a little research on this structure and this is my conclusion on the topic.
The information plaque on the bridge states the bridge was built in 1925. This is the year the bridge was constructed, but the bridge did not open until early 1926.
The current bridge replaced an older structure that was built in 1903-04. This older bridge is probably the source of confusion for the date of the current bridge.

NOTE: Original bridge parts were used to cross the canyon where present day Interstate highway I-5 is located. (AKA Terwilliger Curves )---This is a notorious location for traffic wrecks due to the curve configurations.
AKA "Suicide Bridge" for obvious reasons--
Several streetcar car wrecks occured on the bridge involving runaway Council Crest streetcars-
