BARS::University Dr. Exit on I-10 East in Phoenix, Arizona

These road signs were found approaching the University Drive exit on eastbound I-10 in Phoenix, Arizona.

The road signs say...

   +----------+ +-------------------------+
   |   Lane   | | University Dr       1/4 |
   |   Ends   | | 40th St               1 |
   | 1/2 Mile | | 143 - 48th St         2 |
   +----------+ | Broadway Rd             |
                +-------------------------+

   the numbers are:  (1/2)  (1/4)  40  1  143  48  2

   the math is:  48 - 40 + 2 + ((1/2) / (1/4)) = sqrt(1 + 143)

   observe...
      1/2 / 1/4 = 2
      48 - 40 + 2 + 2 = 12
      sqrt(1 + 143) = sqrt(144) = 12
