I thought this bridge over the South Umpqua River at Winchester, Oregon was nice looking. The photo was shot from the fish ladder at the dam below. The bridge carries Highway 99 over the river. Beside it sits the Interstate 5 freeway bridge.

"Design - The Winchester Bridge is the longest bridge designed by Conde B. McCullough during the 1920's. The bridge has a unique Tudor Gothic architectural style incorporated into the curtain walls and railing."
