Where is Route 66 in St. Louis?
Where is Route 66 in St. Louis? Two Missouri highways, 366 and 100, claim to be the old Route 66. Why? Because it changed over the years. Both have legitimate claims to Route 66 heritage, so let’s talk about the history, how far apart the roads are, and what makes both of them interesting.
There were at multiple alignments of Route 66 through St. Louis from 1926 to 1975, so no wonder it’s complicated. The two major ones are the 1926-32 version, along the modern MO-100, and the post-1932 version, which is approximately MO-366. There was also a bypass route, which served approximately the same function as the modern I-270/I-255 outerbelt today, but it was closer to the city, and all on the Missouri side.
