BARS::IL Hwy-84 and US Hwy-20 in Illinois Evaluate to Phi

These highway signs were found in the northwest part of Illinois along the Mississippi River.

The signs say...

   +-------+  +-------+
   | IL 84 |  | US 20 |
   +-------+  +-------+

   the numbers are:  84  20

   the math is:

   log(sqrt(84 x 20)) = 1.61265

   84 x 20 = 1680
   sqrt(1680) = 40.9878
   log(40.9878) = 1.61265

   note: the golden ratio 'phi' = 1.61803399

   These signs evaluate to Phi if 1.61265 and Phi are
   both truncated to the hundreths.
