Wow!......this is a beauty!! Puts me in mind of the ill-fated Bridgeport Bridge. Hard to believe they would have built such an ornate span in the 1920's, looks more like something from the late 1800's.

Warren Rd bridge is located entirely within Baltimore County, but since Loch Raven Reservoir and the Warren Rd bridge are owned by Baltimore City, it is classified as such in the National Bridge Inventory.
