Field visited this bridge June 2016. If this bridge is open to traffic it is during low water levels only only... the river was more like a lake east of the bridge and deep water was over the road, and the road gated off. The bridge was still "open to traffic" if we expand the definition of "open to traffic" to include fishermen parking their car on the bridge to interfere with my photos. I can also explain the graffiti... one of the locals (sounding quite proud of this) announced to me that graduating high school students paint their name and graduation year on the bridge. Indeed much of the graffiti appeared to be of this variety.
The same thing used to happen with the more famous Route 66 Brush Creek Bridge in Cherokee Co. but a good coat of white paint took care of that. That one seems to remain graffiti free.
This bridge seems to get more covered in graffiti ever year.
Oh gee, another example of what you call mixing cans of spraypaint with a bunch of morons. The graffiti covering this historic bridge is utterly appalling.
This area gets backwater from John Redmond Reservoir IIRC. I seem to remember that this road could get barricaded on occasion. There used to be a MASSIVE log jam just upstream from the bridge which I am sure made the problem worse.
This bridge always seems to have a new layer of paint.
Hope you still got some good pics.
