Kudos to the commuters who brave these winding routes every day.

Making it through the Alphabet Loop around downtown Kansas City, Missouri: 3.45 miles, eight different highways, 23 exits, and a crash rate that's three times the state average, is not an easy feat.

Even though the original Spaghetti Junction is in th U.K., Atlanta's version looks more intimidating from above. British drivers, however, consider their Spaghetti Junction as one of the scariest in the country.
