The news stories said that ADOT was seeking our input on its study of passenger rail between Phoenix and Tucson. It isn't seeking my input for reasons that will become apparent, but here goes anyway.
It was always a joke renaming this entity the Arizona Department of Transportation. It was and remains in spirit the Arizona Highway Department, committed to building highways. The glory days were under state engineer William Price (1963-1977), when Arizona could boast some of the finest highways in America, before population growth and underfunding overwhelmed the agency.
Also under Price, the Highway Department began its swerve from serving the public interest to private interests and it's never looked back. You can see an early indication in the odd, seemingly illogical, westward shift the Black Canyon Freeway makes between Northern and Dunlap in Phoenix. This mission became gospel with the metro Phoenix freeway system, most of which was built to benefit private land owners whose worthless desert was suddenly highly profitable because a freeway was coming. The damage done to the city by the ensuing sprawl was catastrophic and is probably irreversible.
