The eastern routes are generally situated from the east bank of the Missouri River in Iowa and Missouri, through eastern Kansas, and across Nebraska. The central routes are generally in Wyoming, northern Utah, and eastern Nevada. The western routes are in Nevada and California. Some of the study routes, such as the Overland Trail and the Bidwell-Bartleson Route, cross more than one of these geographic regions.

Other trails in the feasibility study include Oregon National Historic Trail, Pony Express National Historic Trail, and Mormon Pioneer National Historic Trail.
