OWR&N = Oregon-Washington Railroad & Navigation

All of the documents I looked at call it Joso Bridge, but it is actually right next to Perry, Wa.

The tiny yellow stripe atop the Joso Bridge (built 1914) is the Union Pacific 150th Anniversary Train crossing the Snake River at Perry, Washington - July 9, 2012. The bridge is the longest and highest bridge in the Union Pacific system.

In 1914, this railroad bridge was one of the longest, 3920', and highest, 285', RR bridges in the world. It is still the longest and highest on the UP system. "The new bridge cut 52 miles and four and a half hours off the old Spokane to Portland route, perhaps justifying the railroad’s $2,000,000 investment. The toll in human life was harder to justify. Many workers succumbed to caisson disease as they dug sixty five feet into the river bottom to provide a solid footing for the piers. Others fell from the steel that carries the rails 285 feet above the water. Their bodies were often swept far downstream where they would be recovered days or weeks afterwards."

And right behind you is the UP trackage that the Great Northwest uses.

I didn't catch a train while I was flying this weekend, but did grab a few nice drone pics of this monster viaduct.
