BARS::Four US Highways Signs in Memphis, Tennessee

These highway signs were found on S. 3rd Street in south Memphis, Tennessee.

The highway signs say...

   +-------------------------+
   | US Hwy-70  |  US Hwy-79 |
   | US Hwy-61  |  US Hwy-64 |
   +-------------------------+

   the numbers are:  70  79  61  64

   the math is:  sqrt(79 - 70) + 61 = 64

   observe...
   	79 - 70 = 9
   	sqrt(9) = 3
   	3 + 61 = 64
   
   prime numbers:  61, 79
   square number:  64
