Not much is known about Benedict Pass, only that it is a railroad bridge out in the desert connecting the railway in Armadillo, Cholla Springs with Benedict point in Gaptooth Ridge which continues on across the San Luis River into Mexico. Marshal Leigh Johnson says that the bringing of the railroad served by the Benedict Pass bridge made the former mining town of Tumbleweed become a ghost town.
The cheat code for Decreased Bounty (THEY SELL SOULS CHEAP HERE) is found carved into the side of the bridge.
Lewis Shelton mentions that a friend of his was shot on the bridge.
The bridge is featured at the beginning of the official launch trailer for Red Dead Redemption.
