In preparing for this series, this is the bridge that caught my fancy, a railroad bridge. Built in 1925 for a logging spur that brought logs to the Frank Chambers Mill in Cottage Grove, OR, USA, the bridge crosses the Coast Fork of the Willamette River. It's 78 feet (23.8 meters) long and is of the Howe truss type. Quite simply, it's massive to support the weight of a loaded log train, like this perhaps. There are eight, four per side, hand hewn beams running the length of the bridge. They were hand hewn because the wood fibers would have been crushed by saw mill cutting of the lumber making the absorption of moisture easier. Pairs of beams running perpendicular to the main supports carry all the additional supports necessary for the rails.
Unfortunately, the Chambers Mill burned in 1943 and the bridge was abandoned. It has been slowly decaying since then and is in sad shape. The beams carry the scars of unsuccessful attempts by arsonists to burn it down. The entire structure leans to the right when viewed from the front. I'm glad I saw it before it's gone.

I'll be busy the next few weeks. Commenting will be spotty at best.
