I spent a few months in Houston. Coming from the Canadian prairies with Calgary as my biggest city, Houston was a cultural experience in traffic design.

I saw six freeways stacked overtop each other. That assumes I was driving on the bottom of the stack, which may or may not be the case. One of those highways was the 610, the ring road. Maybe #59 was one of the others, I can't remember fully.

Civil engineers in the USA must use a lot of drugs.
