Dave Oosterhuis brings another mathematically significant roadsign from Minnesota. This sign is right in the backyard of the founder of Road Sign Math, who is ashamed to realize that he never recognized this one.
Very nice math in this sign. The 18 goes into the 36 wonderfully.
{36 \over 18} = \sqrt{4}
This sign is on I-35W northbound just after you cross the Mississippi river. The GPS coordinates are approximately N44 58 47.6 W93 14 40.3. See sign on map!
