This road closed sign is on CA Hwy-209 in San Diego, California.

The road closed sign says...

   +---------------------+
   |     Road Closed     |
   |    1,000 Ft Ahead   |
   |     5 PM - 5 AM     |
   | Weekends & Holidays |
   |     5 PM - 9 AM     |
   +---------------------+
   the numbers are:  1,000  5  5  5  9

   the math is:  5 / 5 + 5 - sqrt(9) = log(1000)

   observe...
      5 / 5 = 1
      1 + 5 = 6
      sqrt(9) = 3
      6 - 3 = 3
      log(1000) = 3

   [solve for 'n']  n / n + n - sqrt(9) = log(1000)

   --- the following was added on 5 October 2008 ---

   factorial math:  (5! / (5! / sqrt(9)!))! / 5!) = log(1000)!

   more math:  log(sqrt((1000 / (5 + 5)))) + 5 = sqrt(9)!

   rsHwyEval:  (1000 / 5) * (5 / 5) + 9 = 209
   * This sign was found on CA Hwy-209.

   rs42Eval:  (1000 / 5) / 5 + sqrt(9 - 5) = 42
   * 42 is the "Answer to Life, the Universe, and Everything"

   rsAgeEval:  (1000 / 5) / 5 + sqrt(9)! + 5 = 51
   * MathBabbler found this math when he was 51 years young.

   base-2 math:  9 - 5 = (1000 / (5 + 5))2

   more base-2 math:  sqrt(9 - 5) = sqrt(1000 / (5 + 5))2
