Description 

Ownership appears to be BNSF as the locked gate sign implies. The road south of the bridge appears to be used both by BNSF and irrigation control. There is a diversion dam where the road ends. This leads me to believe that the new US97 was constructed at the same time to allow for the dam to be built, causing the abandonment.

NBI has this bridge in the wrong location as I82 does not cross Ahtanun Creek.
