Currently carries conveyor belt and access road from quarry to nearby concrete plant nearly adjacent to Big Hell Canyon RR Bridge.

Google Maps/Earth erroneously depict County Road 71 accessing and crossing this bridge; in reality CR 71 crosses the railroad and passes the cement plant. Direct road access to this bridge is restricted, but it can be reached by hiking.

The bridge is drivable and used by some company vehicles.

I should note that the premises are marked as under video surveillance, and every time I have attempted to access the area around this bridge for photographs of the nearly adjacent BNSF viaduct, I have been "checked out" by company employees. Typically because I'm a "local" and show no intention of going out onto the bridge or conveyor belt itself, I'm dismissed with appropriate warnings. (It doesn't hurt that I'm usually decked out in personal protective equipment, railroad-issue hard hat, safety boots, etc. And this IS snake and scorpion territory, after all.)

Even without the conveyor apparently on the bridge, I question whether this bridge would be drivable. When I visited a few years ago, the approaches were blocked off and gated, and there were trenches about three feet deep on either end of the concrete deck. "Somebody" obviously doesn't want anybody driving on this bridge, probably for good reason. I hiked in.

There is now a conveyor of some sort placed on this bridge's deck. http://www.panoramio.com/photo/36018350 http://www.panoramio.com/photo/36018337
