BARS::Phi Sign Found on I-25 in Albuquerque, New Mexico

This road sign was found on northbound square-numbered I-25 in Albuquerque, New Mexico. The road sign was found on Pi Day 2007.

The road sign says...

   +------------------------------+
   | Sunport Blvd             1/2 |
   | Gibson Blvd            1 1/4 |
   | Avenida Cesar Chavez   2     |
   +------------------------------+

   the numbers are:  (1/2)  (1 1/4)  2

   the math is:  (1 1/4)^(1/2) + reciprocal(2) = Phi (1.61803399)

   observe...
      1 1/4 = 5/4
      sqrt(5/4) = sqrt(5)/2
      reciprocal(2) = 1/2
      sqrt(5)/2 + 1/2 = Phi
