Table 3-5. Share of Vehicle Miles of Travel by Highway System

Most freight moving by truck uses the Interstate System.  Although all vehicle miles of travel are divided about equally among Interstate highways, the balance of the National Highway System (NHS), and other public roads, the Interstate System carries about one-half of truck travel and three-fourths of travel by freight-hauling trucks serving places at least 50 miles apart.

Table in Excel format

Percent

	Interstate Highway	Balance of National Highway System	Other Highways
All vehicles	35	30	35
All trucks	49	26	25
Freight-hauling trucks serving places at least 50 miles apart	75	20	6

Notes:

Percentages are based on the Interstate Highway, Balance of NHS, and Other Highways mileage included in the FAF network.  Shares by vehicle type may differ from other FHWA publications. Numbers may not add to totals due to rounding.
