BARS::7th Ave., 19th Ave., I-17 on I-10 West in Phoenix, Arizona

This road sign is on westbound I-10 in Phoenix, Arizona.

The road sign says...

   +----------------------+
   | 7th Ave          3/4 |
   | 19th Ave       1 1/2 |
   | Jct I-17       2     |
   +----------------------+
   the numbers are:  7  (3/4)  19  (1 1/2)  17  2

   the math is:  sqrt(7 - 2 * sqrt(3/4 + 1 1/2)) + 17 = 19

   observe...
      3/4 + 1 1/2 = 2 1/4
      sqrt(2 1/4) = sqrt(9/4) = sqrt(9)/sqrt(4) = 3/2
      3/2 * 2 = 3
      7 - 3 = 4
      sqrt(4) = 2
      2 + 17 = 19
