The Fort Bridger Route—that is, the main route—of the Oregon Trail crossed the Big Sandy at present Farson, Wyo. Just west of the intersection of Highway 28 and U.S. Highway 191 in Farson are two historical markers. A few yards south of these markers, a modern bridge crosses the Big Sandy. This is where the main route forded the river. In later years, there was a stage and Pony Express station at the site.
