The distance between the East Coast and the West Coast of the United States ranges between 2,600 and 3,200 miles, depending on the route. The shortest route is referred to as the Southern Pacific route or Route 80, while the longest road is Route 50.

The 3,200-mile route from the east to the west is US-50 or Route 50, which passes through the middle of the country, earning the nickname of the Backbone of America. Starting in San Francisco, this route passes through the deserts of Nevada and Utah. It crosses the Rocky Mountains of Colorado before hitting the Colorado and Kansas prairies. Next, this route continues through the heartland country, passing through the fields of Missouri, Illinois. Indiana and Ohio. It finishes by climbing the Appalachians, passing through Washington, D.C. and ending in the fishing communities of Maryland.

The shorter distance between the two coasts is 2,671 miles and begins in San Diego between the border of California and Mexico. It passes through the arid deserts of Arizona, New Mexico and northern Texas. This route then reaches the cotton fields of northern Louisiana, the plantations of Mississippi and then the prairie of Alabama. This route completes in Georgia in the coastal town of Savannah.
