The Mojave Road, also known as Old Government Road (formerly the Mohave Trail), is a historic route and present day dirt road across what is now the Mojave National Preserve in the Mojave Desert in the United States. This rough road stretched from Beale's Crossing (the river crossing site on the west bank of the Colorado River, opposite old Fort Mohave, roughly southwest of Bullhead City, Arizona), to Fork of the Road location along the north bank of the Mojave River where the old Mojave Road split off from the route of the Old Spanish Trail/Mormon Road.
