Metric highways signs? That's right, in the mid-1970โs the metric system was promoted across the country as the preferred system of weights and measures. In response, WisDOT placed destination-distance signs with metric units along several interstates. Locations included I-94 westbound in Milwaukee and I-90/94 eastbound in Tomah.
The metric system was never adopted in the U.S. By the early 1990โs the metric signs were replaced with signs using todayโs imperial system.
Do you think the U.S. should have used the metric system?
