The Transcontinental Motor Convoys were early 20th century vehicle convoys, including three US Army truck trains, that crossed the United States (one was coast-to-coast) to the west coast. The 1919 Motor Transport Corps convoy from Washington, D.C., to San Francisco used the incomplete Lincoln Highway.
