Todd Southworth, a newcomer to Road Sign Math, found this mathematically significant road sign a number of times on his way home. However, until he visited this site he didn't appreciate the wonderful math contained inside it.

This sign is on eastbound CA-210 just east of I-15 in Fontana, California.
