This exhibit is an outline map of the 48 contiguous States and insets for Alaska and Hawaii showing the Interstate and non-Interstate routes for average daily long haul traffic on the National Highway System. Freight volume is indicated by line thickness for 50,000 trucks per day, 25,000 trucks per day, and 12,500 trucks per day. The Interstates with the highest volume per day run primarily from Massachusetts to Texas, from Ohio to Tennessee, and from Illinois to neighboring states. The Interstates with 25,000 trucks per day run mainly across the southwestern states, across the Great Plains States, and along the Pacific coast. The Interstates with 12,500 trucks per day run mainly across the upper northern states from the Midwest to the Pacific coast, as well as through the Great Plains states. Non-Interstate highway system routes have the highest volume in California.
