Before it was on Lindbergh, what was US 67's routing through STL?
There were several routings. The earliest I see based on https://www.modot.org/missouri-highway-map-archive-1918-2014 shows following the broadway 7th up to downtown and then crossing over to Illinois at downtown.
It was on Kingshighway for a while. Parts of Lindbergh at one time was Bypass 40, 66, and 67.
