BARS::Forest Road 249 Along US Hwy-191 in Arizona

This road sign is along US Hwy-191 in Arizona.

The road sign says...

   +------------------+
   | Big Lake      17 |
   | East Fork        |
   | Black River   12 |
   | Three Forks   12 |
   +------------------+
   | 249 |
   +-----+

   the word "three" becomes the number 3

   the numbers are:  17  12  12  3  249

   1st off-by-one math:  sqrt(249 + 3! + 12 / 12) = 17 - 1

   observe...
      3! = 6
      12 / 12 = 1
      246 + 6 + 1 = 256
      sqrt(256) = 16
   
   2nd off-by-one math:  sqrt(249 - 12 - 12) + 3 = 17 + 1
   
   observe...
      249 - 12 = 237
      237 - 12 = 225
      sqrt(225) = 15
      15 + 3 = 18

   the math is:  12 / 3 + 17 = ceil(249 / 12)

   observe...
      left-side:
         12 / 3 = 4
         4 + 17 = 21
      right-side:
         249 / 12 = 20.75
         ceil(20.75) = 21   [round up to nearest integer]

Note: This road sign was discovered on Pi Day 2008.
