Although the new game Mafia III is intended to depict New Bordeaux, a fictional recreation of New Orleans in 1968, the likeness of the Julien Dubuque Bridge makes an appearance in the game. The portal bracing in the game is almost 100% identical to the Julien Dubuque Bridge, and the sway bracing (particular at the pier points) as well as the concrete pier's inset arched design are strikingly similar as well.

I found to bridge passes for the Dubuque bridge, one was for a "team" and the other for an automobile, on the back it talks about not speeding on the bridge but there is no date on these passes can anyone tell me something of the time frame they were used.
