As alluded to in the overview, the post was a key transportation and supply point in Wyoming. In addition to the pioneers traveling west on the Oregon Trail and the telegraph line, which crossed over on the bridge itself, others used the crossing as well. These included fur traders, mormons (who opened a ferry and supply depot here), and riders of the Pony Express from 1860-1861.
The post's importance began to decline in the mid-1860s. The army's focus shifted to the southern part of the state after the transcontinental railroad and new telegraph line were built to the south. In October 1867, the army officially abandoned the post and ranchers and homesteaders began moving in the area in the 1870s.
