IIRC, it was an interesting coalition of enviro's and conservatives that resisted freeway construction way back when. Fast forward and at this point Metro Phoenix must have one of the nicest freeway systems in the country - although a couple of Denver bloggers were just discussing Minneapolis-St. Paul's very good system.
Colorado/Denver stands in sharp contrast. Every
major project now involves a P3 (which is OK) that includes an HOV/express toll lane(s).
CDOT is preparing to start construction on what will be a (I-70) rebuild comparable to I-10 including a lid for a park. It will be 10 lanes with the interior 4 lanes providing two lanes each way of strictly tolled lanes. On the outside will be 3 FREE lanes each way. It's also a copy of what FDOT has already started with the I-4 in Orlando. Here's an
Orlando/I-4 rendering. I had to laugh as when I went to retrieve that from Google images the 1st image I wanted was from one of my previous posts on the Denver transportation thread. I have no idea how such things happen.
After cobbling together some funds for rebuilding half of the U.S. 36 corridor from Denver to Boulder CDOT solicited a P3 for the other half. It will mostly be a 6 lane highway, 3 eaach way with the inside lane being an HOV/express toll lane. Starting in 2017 cars will need 3 occupants to use the HOV lane toll-free. There will be BRT or really upgraded
express bus service. When completed end of this year "Plenary Roads" will maintain, repair and collect tolls under a 50 year contract. That's damn near 5 decades.
Big Texas has Big Needs. I read recently that in the Dallas metroplex alone they have a need for $25 billion in new road construction of which only a very small percentage has started. Most of their new roads also include HOV/express lanes if not tolled lanes.
For now at least Metro Phoenix is in great shape at least so far as freeways are concerned.
