Ep 13: How Interstate Highway Numbering Works (and Why I-60 Doesn't Exist)

Mastering the Commute: Episode 13 – How Highway Numbers Really Work (and Why I-60 Doesn’t Exist)

 Ever seen a meme showing I-50 or I-60 running across the U.S.? Spoiler: they don’t exist—and there's a fascinating reason why. In this 6-minute episode, I take you through the history and logic of America’s highway and interstate numbering systems, from the old U.S. Highways like Route 66 to the massive Eisenhower Interstate system.

We’ll explore:
 🚧 Why I-50 and I-60 were skipped
 🛣️ The difference between U.S. Highways and Interstates
 🔢 How loops, spurs, and 3-digit interstates get their numbers
 🛑 The politics behind strange routes like I-99 and I-238
 🌎 Why California and New York freeways love naming things (hello “the 405”)
 🌾 What’s up with State Highways, County Roads, and Texas Farm-to-Market roads

🎯 Whether you’re a daily commuter or a fellow road geek, this one’s packed with facts you’ve probably never heard—plus a few rabbit holes for the truly curious.
