Ideas for curved bridge

[kjd]

I know of yet another curved girder twin-track RR bridge: CSX in Baltimore, at the north end of the Howard Street Tunnel. I couldn't figure out how to save the exact location in a URL, but go to Googlemaps.com and type in the search address: 1848 Falls Rd., Baltimore, MD. Then click the magnifying-glass button and that will take you right to it.

The entire bridge is indeed curved but made up of the traditional shorter straight segments.
