How far apart are rest stops on US interstates?
Updated October 2026
There is no national rule for how far apart rest areas must be. States decide where to build them, and many have closed older rest areas over the last twenty years. As a result, the spacing varies from a few miles on busy eastern interstates to well over 100 miles in parts of the West.
We calculated the gaps from our own list: rest areas, welcome centers and service plazas, ordered along each interstate. Distances use state mile markers where both stops have one, otherwise the straight-line distance plus 15 percent. Truck stops and gas stations are not counted, and they often fill the gaps.
Plan breaks before you need them
Safety agencies recommend a break about every two hours of driving. On a stretch with a long gap, stop at the last rest area before it, or plan a fuel stop in a town. Each rest stop page on this site shows the distance to the next stop in both directions.
