Missouri Interstate Trivia

  • Missouri has 17 interstate routes, which total 1,180 miles.  They include: I-29, I-35, I-44, I-55, I-57, I-64, I-70, I-72, I-155, I-170, I-229, I-255, I-270, I-435, I-470, I-635, I-670.
  • Missouri’s capital, Jefferson City, is one of only five state capitals not directly served by the interstate system.
  • Because U.S. 50 passes through Missouri, interstate 50 does not exist because it would have most likely also passed through Missouri.  National standards discourage interstates and U.S. highways with the same number to exist in the same state.
  • Interstate 70, which bisects Missouri, is the fifth longest interstate route (2,153.13 miles from Cove Fort, Utah, to Baltimore, Maryland).  It was built between 1956 and 1965, which also makes it one of the nation's oldest interstate highways.
