Most People Don’t Know The Only Metric Highway In The Country Is Right Here In Arizona

Perhaps some of you readers may remember back to a time when the U.S. attempted to convert to the metric system? Perhaps you remember using metric units in school or when your high school track was converted to one measured in meters instead of yards. While the 1975 Metric Conversion Act didn’t quite go as planned, you can still find evidence around the country of that attempt. In fact, one prominent example exists right here in Arizona on one of our state’s busy highways.

During these uncertain times, please keep safety in mind and consider adding destinations to your bucket list to visit at a later date.
