Three Other Unique Things About I-8
There are 3 things worth knowing about I-8 which are not stops but, as in your original idea, talking points.
1) I-8 is the only Interstate that descends significantly below sea level. It gets down to -52' as it crosses the Imperial Valley south of El Centro.
2) If you pay attention as you traverse Telegraph Pass east of Yuma, you will note another oddity. I-8 crosses itself, with the eastbound and westbound lanes swapping sides. For about a mile you will be driving on the left.
3) Excluding the H-# highways in Hawaii (which clearly aren't INTER-state), I-8 is the Interstate that crosses the newest part of the United States. When you enter Arizona you will, as Bob notes in his article, be following the railroad. The land south of the Gila River was not part of the original land ceded after the Mexican-American war, but was rather bought later specifically for the right-of-way for the railroad.
