BARS::I-10 and US Hwy-60 Entrance Ramp in Tempe, Arizona

These highways signs are on the I-10 and US Hwy-60 entrance ramp at Baseline Road in Tempe, Arizona.

The highways signs say...

   +---------------------+ +--------------+
   | I-10   US-60   West | |    Exit  154 |
   |       Phoenix       | | US-60   East |
   +---------------------+ |    Mesa      |
                           |    Globe     |
                           +--------------+
 
   the numbers are:  10  60  60  154

   the math is:  60 - sqrt(154 - 10) = 608

   observe...
      154 - 10 = 144
      sqrt(144) = 12
      60 - 12 = 48
      base-8 is the "octal" number system
      608 = 6 * 8 + 0 * 1 = 48
