this is the chain of rocks highway bridge and it is on historic Route 66. I would have taken the 2 mile walk to the actual historic bridge had it not been raining.

Based on the full-length diagonals alternating (Changing direction), I feel it is correctly labeled as a sub-divided Warren.

I believe the design of the main span is a Parker (Camelback) subdivided Pratt through truss.

This bridge is now a one lane bridge. There is a stoplight at either end that allows traffic to cross only one direction at a time. The other lane has been converted to a pedestrian and bicycle lane.
