US 60-61-62 converge in Sikeston, MO

(Last updated 5/27/2020)  Currently Sikeston is the only place where three consecutive US route numbers intersect -- US 60, US 61, and US 62:

The overpass shown there carries modern US 60.  Historically the three routes converged a couple miles straight ahead, at the intersection of Main Street and Malone Avenue, or what is now the junction of Business 60 - US 61 - US 62:

Today Bus. 60 shares pavement with US 61-62, but historically the three mainline US routes have never overlapped, only intersected.  However: historically US 23, US 24, and US 25 had a junction in Toledo...

...and there was a brief period during which all three routes did share the same pavement.  This was on a two-mile stretch of Detroit Avenue, between Cherry Street and Telegraph Road.  That arrangement was documented on this map:

Not shown on that 1956 map above is Reynolds Road, which is a bit further west, but for a time it carried Bypass 23-24-25.  Jim Lindsay drove that road in 1959 and recalls that it was signed with non-standard elongated shields.  There are no known photos, but this illustration is an attempt to recreate how those shields looked:

I can't say I'm a huge fan, but I will award some points for a creative solution to an unusual situation.  As far as the mainline routes, their triple-overlap was already gone by the 1950s.  And then in 1974 the US 25 designation was removed from both Ohio and Michigan.
