BARS::Highways Signs at AZ Hwy-87 Junction with AZ Hwy-187

The following collection of highways signs are on southbound AZ Hwy-87 at its junction with AZ Hwy-187. RoadHacker saw the signs on 10 March 2008, but he didn't get a picture.

The highway signs say...

   +-----------+ +------------+
   |   South   | |    --->    |
   | AZ Hwy-87 | | AZ Hwy-187 |
   +-----------+ +------------+
           +------------+
           |    --->    |
           |    I-10    |
           +------------+
   the numbers are:  87  187  10

   the math is:  sqrt(187 - 87) = 10

Note: AZ Hwy-187 connects AZ Hwy-87 with I-10 and it is approximately five miles in length.

Update::2013.11.21

RoadHacker got a picture of these signs on 17 November 2013.

This BARS was created on 11 March 2008 and since then rsCardinality was added to the BARS system.

   the numbers are:  87  187  10

   rsCardinality:  sqrt(187 - 87) + log(10) = 3
   * There are 3 numbers in these signs.
