In following years, trader John Baptiste Richard established a trading post several miles downriver of the crossing. The U.S. Army established its first presence in the area in 1855, erecting Fort Clay near Richard's trading post. In 1859, when the site was part of the Nebraska Territory, Louis Guinard built a competing bridge at the trading post, called the Platte Bridge Station, at the site of the old Mormon Ferry crossing. From 1860–1861, the Pony Express operated a station at the site.
