About a month ago I was traveling on I-265, one of the spurs that loops around Louisville, KY when I noticed the road signs had changed to metric for about a 5-10 mile stretch. I've not traveled this route often or recently, so I can't say for sure how long the signs have been there, but it looks like an area of the interstate that has been redone recently.
I'm aware of some areas of the US that retain metric signage from decades ago when the US was exploring switching over to metric, but I'm certain these road signs have been installed in the not-too-distant past. Of course in areas near the border it's common to see metric, but I'm baffled as to why they chose metric as the dominant unit (with imperial in parentheses) in this area of northern KY, 400+ miles from any border. The speed limit signs were in MPH, I never thought to check the mile markers; they are probably in miles too.
Anyone see anything similar in other places, or is there a reason why the road signs are done this way?
