Metric signs on roads in the U.S.
This Web page is devoted to examples of signs showing metric measurements (mostly on roads) in the U.S.
Viewers are encouraged to send examples of other metric signs, including information on where the signs are located and when the photographs were taken, to the USMA Webmaster.
There are two ways to view the signs:
Click on a state symbol on the map to see signs in that state.
Scroll down to browse through all signs; the most recently added are at the top.
Not all signs shown meet current standards; see the MUTCD standards for metric road signs in the U.S..
Only states with sign photos are clickable. Some items cross state lines, so the same signs may appear on more than one state's page.
