Fort Hall was a fort in the Western United States that was built in 1834 as a fur trading post by Nathaniel Jarvis Wyeth. It was located on the Snake River in the eastern Oregon Country, now part of present-day Bannock County in southeastern Idaho. Wyeth was an inventor and businessman from Boston, Massachusetts, who also founded a post at Fort William, in present-day Portland, Oregon, as part of a plan for a new trading and fisheries company. In 1837, unable to compete with the powerful British Hudson's Bay Company, based at Fort Vancouver, Wyeth sold both posts to it. Great Britain and the United States both operated in the Oregon Country in these years.

Butterfield Overland Mail was a stagecoach service in the United States operating from 1858 to 1861. It carried passengers and U.S. Mail from two eastern termini, Memphis, Tennessee, and St. Louis, Missouri, to San Francisco, California. The routes from each eastern terminus met at Fort Smith, Arkansas, and then continued through Indian Territory (Oklahoma), Texas, New Mexico, Arizona, Mexico, and California ending in San Francisco. On March 3, 1857, Congress authorized the U.S. postmaster general, at that time Aaron V. Brown, to contract for delivery of the U.S. mail from St. Louis to San Francisco. Prior to this, U.S. Mail bound for the Far West had been delivered by the San Antonio–San Diego Mail Line since June 1857.
Henry Harmon Spalding (1803–1874) and his wife Eliza Hart Spalding (1807–1851) were prominent Presbyterian missionaries and educators working primarily with the Nez Perce in the U.S. Pacific Northwest. The Spaldings and their fellow missionaries were among the earliest Americans to travel across the western plains, through the Rocky Mountains and into the lands of the Pacific Northwest to their religious missions in what would become the states of Idaho and Washington. Their missionary party of five, including Marcus Whitman and his wife Narcissa and William H. Gray, joined with a group of fur traders to create the first wagon train along the Oregon Trail.
Mullan Road was the first wagon road to cross the Rocky Mountains to the Inland of the Pacific Northwest. It was built by U.S. Army troops under the command of Lt. John Mullan, between the spring of 1859 and summer 1860. It led from Fort Benton, which at the time was in the Dakota Territory, then Idaho Territory from July 1863, and into Montana Territory beginning in May 1864. The road eventually stretched all the way from Fort Walla Walla, Washington Territory, near the Columbia River to the navigational head of the Missouri River, which at the time was the farthest inland port in the world). The road previewed the route approximately followed by modern-day Interstate 15 and Interstate 90 through present-day Montana, Idaho, and Washington.
Fort Boise is either of two different locations in the Western United States, both in southwestern Idaho. The first was a Hudson's Bay Company (HBC) trading post near the Snake River on what is now the Oregon border, dating from the era when Idaho was included in the British fur company's Columbia District. After several rebuilds, the fort was ultimately abandoned in 1854, after it had become part of United States territory following settlement in 1846 of the northern boundary dispute.

Kelton is a ghost town, just north of the Great Salt Lake, in the Park Valley area of Box Elder County, Utah, United States. The town was inhabited during the period of 1869–1942. Once an important section station on the First transcontinental railroad, Kelton was dependent on the railroad throughout its history. The town suffered serious setbacks in the 1880s when its busy stagecoach route to Boise, Idaho was discontinued, and in the 1900s when the Lucin Cutoff left it off the main rail line. The strongest earthquake in Utah history caused severe damage in 1934, but Kelton ceased to exist only when the rails were completely removed during World War II.
The Overland Trail was a stagecoach and wagon trail in the American West during the 19th century. While portions of the route had been used by explorers and trappers since the 1820s, the Overland Trail was most heavily used in the 1860s as a route alternative to the Oregon, California, and Mormon trails through central Wyoming. The Overland Trail was famously used by the Overland Stage Company owned by Ben Holladay to run mail and passengers to Salt Lake City, Utah, via stagecoaches in the early 1860s. Starting from Atchison, Kansas, the trail descended into Colorado before looping back up to southern Wyoming and rejoining the Oregon Trail at Fort Bridger. The stage line operated until 1869 when the completion of the First transcontinental railroad eliminated the need for mail service via stagecoach.
The history of rail in Oregon predates the transcontinental railroad in 1869.
