The Colorado Dept. of Transportation last week finalized a controversial contract with private consortium Plenary Roads Denver to build the second phase of the U.S. 36 Managed Lanes project. The two-phase project expands and improves the main freeway between Denver and Boulder.

It adds a "managed lane" in each direction for bus rapid transit, high-occupancy vehicles and drivers willing to pay a toll along the 30-mile road. It also improves the existing non-tolled lanes, adds a commuter bike lane and creates one of the state's first diverging diamond interchanges.

该合同要求全体会议维护高速公路，包括未来50年的降雪和冰冰。作为交换，该财团将在此期间从托管车道收集通行费。每种方式都不会收费两条车道。

第二阶段设计建造部分的全体会议标签为1.2亿美元，再加上近5400万美元，以偿还该项目的联邦贷款。美国36次改进的总标签为4.25亿美元。

This project is the first highway public-private partnership in the state's history, and critics complain that key project provisions may have been withheld.

CDOT previously released an 80-page summary of the P3 contract but, until mid-February, had refused to reveal the entire 600-page contract, citing protection of proprietary elements. Two U.S. 36 public meetings in February drew raucous crowds of nearly 700 people concerned about the 50-year length of the contract, its risks, possible high tolls and a general wariness about handing over control of a public road to private interests. State lawmakers who also had been denied access to the contract chimed in. "We have a private company that will now be dictating what's going to happen on that highway," said Sen. Matt Jones (D-Louisville).

“有大量的错误信息。的contract is fine," says CDOT spokeswoman Amy Ford. "It shifts risk and highway maintenance to the private sector and allows us to complete major improvements that otherwise wouldn't get done for 20 years. The lesson learned here is that we need to do a better job of educating the public—ahead of time—about the need for P3s and their benefits and how these projects won't get done without them."
