Rail

One of these days, those thugs will follow the wrong person home...

I like high mast lighting. Here in Chicago, several recently-rebuilt expressways use high-mast lighting. You definitely notice the added visibility of it after driving on an expressway or tollway that still uses regular lighting.

The Stevenson Expressway (I-55) is probably the most intensely lit limited-access highway in the United States. It's only 6 lanes wide with a wide median, but it is lined with high-mast lighting on both sides every 500 feet or so for about 16 miles from I-294 to Downtown. The inner-most 10 miles of it from Harlem Avenue to Downtown is straight as an arrow, and seeing it lit with high-mast lighting makes it a sight to see. And you can still get good views of the skyline to boot.

Kudos to Houston for implementing it on such a wide scale. I only hope Atlanta (where freeways are horribly underlit at night) and other cities follow suit.
