The area where Platte Bridge Station was located had been the site of various temporary Army encampments over a period of years before the establishment of the fort, or "station" itself. The fort was located on the south side of the North Platte, near the western edge of present-day Casper, at one several local points where the Emigrant Trail crossed from the south side to the north side of the river. In 1847, during the first Mormon wagon train to present-day Utah, Brigham Young commissioned a ferry at the site for later emigrants. The ferry consisted of cottonwood dugout canoes and planking for a deck, with two oars and a rudder. On June 19, Young named nine men to remain to operate the ferry while the remainder of the party continued the journey westward. A group of Mormons returned to the site each summer between 1847 and 1852 to operate the ferry. The ferry was moved to a different spot on the North Platte in North Casper in 1849. It was eventually replaced with a rope-and-pulley system that could make the crossing in five minutes.
