   | Hwy-287 Florence Blvd    3 |
   | I-8 West                 7 |
   | Tucson                  69 |
   +----------------------------+

The numbers in the sign are 287 3 8 7 69.

   (8 - 3)! - ((287 / 7) + 69) = 10

   [factorial help: (8-3)! = 5! = 5x4x3x2x1 = 120]

   ...or...

   (69 + (287 / 7)) / (8 + 3) = 10

The road sign almost approximates Pi.

           69              69
   ------------------- = ------ = 3.13636363
   sqrt(8^3 - 287) + 7     22

   rounded(3.13636363, 2) = 3.14
   truncated(3.13636363, 2) = 3.13

   pi = 3.14159265

   observe... 

      8^3 is 8x8x8 = 512
      512 - 287 = 225
      sqrt(225) = 15
