Subsequently, this became the major route of travel on this part of the Southern Emigrant Trail, and was used by the San Antonio-San Diego Mail Line, with the exception that Nugent's Pass was discarded in favor of Dragoon Pass as the shorter route to the San Pedro River crossing.[3] A shorter route through Doubtful Canyon used by the Butterfield Overland Mail supplanted this pass for the stagecoach route until the outbreak of the Apache War with Cochise made it unsafe and the Steins Pass route again became the route of choice for many years.[4][5] Stein's Pass became the route the Southern Pacific Railroad used in crossing the Peloncillo Mountains, and the station, later the town of Stein's Pass was founded just east of the summit of the pass.
Today the route of Interstate 10, goes through Stein's Pass.
