What does it say? (My emphasis in red bold)
So the managed (toll) lanes are new additional lanes but existing lanes will be rehabbed too. You will be able to use the rehabbed non-toll lanes, you'll just have to contend with the traffic from everyone else who doesn't want to pay the toll.
I haven't dug in any further but I'll bet the "Friends of the Colorado PUC" has strong ties to unions, environmentalists, and other nutcase lying friends of Bloomberg/Obama/etc. (whoops, sorry that's pretty redundant).
