I-25 plays a significant role in the quality of life and economic vitality of northern Colorado. According to the State Demography Office, the population of Larimer County (316,000) is expected to increase by 52% by 2040. Similarly, Weld County (268,639) is expected to increase by 111% by 2040. In order to provide a better quality of life and economic vitality for the future, improvements are being made on I-25. The North I-25 project is a strategy to provide modern and effective multi-modal transportation solutions for residents, employees, and visitors traveling between Denver and Wyoming.

Currently, CDOT has begun construction to add a new tolled Express Lane in each direction from US 36 to 120th Avenue. As part of the Responsible Acceleration of Maintenance and Partnerships (RAMP) Program, CDOT also plans adds new tolled Express Lane each direction I-25 from 120th Avenue to E-470/SH 7.

Will it be a Public-Private Partnership (P3)?

As part of RAMP, the High Performance Transportation Enterprise (HPTE) reviewed the Environmental Impact Statement (EIS) and Value For Money report to closely examine the construction and lifecycle cost data and potential revenues of the project to determine if it might support a public-private partnership (P3). After reviewing the risks and benefits, it was determined that the project does not yet fit a P3 model.
