Smallest town with a traffic light

[MNHighwayMan]

In Minnesota, there is one location with a traffic signal that is a minimum 5 miles from the nearest town.

Where's that?

Blomkest (157) may have been the winner until the US 71/MN 7 signal was recently replaced with a roundabout.

I thought that maybe was what froggie was referring to, but I didn't even realize that former signal/now roundabout was actually within the corporate limits of a city. There's the signal at US-14/US-71, but that's only a mile or so outside Sanborn, so that's not it either. Hmmm...

Edit: US-75 and US-212. About five miles either way from Madison or Dawson. I think that's it.

Yes, I was referring to 75/212.  Blomkest is only a mile from 71/7.  The 75/212 signal has been the "winner" for years...that signal actually predated the former signal at 71/7.

Did we ever figure out what's the current smallest city in Minnesota with a signal? Without putting too much thought into it, Hilltop has to be close (if we count signals along the city boundary as "in the city") with a population of 744.

Not yet.  Trying to dig through census figures for incorporated municipalities.  That said, a more notable contender for Minnesota would be US 53 in Orr, population 267.

(EDIT)  I believe I've found Minnesota's winner.  Right in the Metro, no less.  I present Mendota, MN:  population 198.  The MN 13/MN 110 signal is partially within the municipal limits.
