Fast Facts: America's Interstate Highway System

Traveling long hours on our county’s Interstate Highway System remains the transportation standard for most Americans. So next time you hit the open road, enlighten your passengers with these fun facts about interstate travel!
  • Planning was underway for America's Interstate System in 1939 as a result of pressure for safer, more convenient travel and an influx of jobs for soldiers returning home from the War. The planned 20-year construction project officially broke ground in 1955 and is still ongoing today. During years of palatable nuclear danger, part of justifying the interstate system was its ability to evacuate citizens of major cities in the event of a catastrophe.
  • While total Interstate mileage has increased, so too have the number of rest areas. As of last week, over 2,800 rest areas combined exist in the contiguous United States. Of that total, over 2,200 have restrooms.
  • The state with the most interstate miles? Considering everything is bigger here, it makes perfect sense that Texas is the answer. The least interstate miles? The Last Frontier, Alaska. The state’s highway system isn’t required to be built to federal interstate standards, as geography dictates road configuration.
  • According to a 2015 article from the Washington Post, California is home the worst highways. Here, 51% of all highways are rated “poor.” Conversely, the best are in Florida, where only 7% of highways are rated as such. In fact, national research group TRIP handed out a “poor” rating to 28% of all the nation's major roadways. A "poor" rating calls for a highway to be replaced, not repaired!
  • To give you an idea of how massive an undertaking Interstate construction has been: 
    • The average mile contains three million tons of concrete.
    • There are 6.6 million tons of concrete in the Hoover Dam.  
    • The current Interstate System runs 46,876 miles.
  • Semi Trucks are among of the most imposing figures on the Interstate System. The U.S. is home to 3.2 million truck drivers, 90% of which work for small trucking companies and owner-operators. As of 2006, semi trucks logged roughly 140 billion miles per year and delivered nearly 70% of all consumer goods.
