American road trip: The 50 longest highways in the US

If you've ever endeavored to drive across the USA, you know that the trip can feel like it takes forever. But even if I-90 feels like it is never-ending, there are actually highways longer than its 3,073 miles in the USA. So what's the longest continuous road in the USA? Scroll through the gallery above to find out. 

There is one pretty famous road missing from the list above, because it no longer officially exists: Route 66. That road would have made it in around the eighth spot, if its almost 2,500 miles were still considered an official highway. Unfortunately, it was decertified in 1985.
