Priority Projects

The Colorado Department of Transportation (CDOT) and the High Performance Transportation Enterprise (HPTE)—a division of CDOT—prioritize transparency, accountability, and public participation in the development and implementation of public private partnerships.

In keeping with its transparency policy, as well as recommendations from a performance audit presented to the General Assembly in March 2015, HPTE provides the following list of priority projects that HPTE is considering for a public-private partnership procurement.

For a complete overview of other CDOT projects that HPTE has assisted with—including US 36 Express Lanes (phases 1 and 2), C-470 Express Lanes, and I-70 West Mountain Corridor Eastbound Peak Period Shoulder Lane (PPSL)—please consult the 2015 HPTE Annual Report.

I-25 North to Wyoming

According to the Colorado state demographers, the population of Larimer County and Weld County are expected to increase by 52 percent and 111 percent, respectively, by 2040. To provide a better quality of life and economic vitality for the future, CDOT has concluded that additional improvements on I-25 North are necessary to provide modern and effective multi-modal transportation solutions for residents, commerce and visitors traveling between Denver and Wyoming. However, preliminary review by HPTE indicated that major improvements are not, at this time, a likely fit for a public private partnership approach.  An updated Level 2 traffic and revenue analysis (which assumes an HOV 3+ policy) has been completed and is being used to determine the financial viability of I-25 North Metro Express Lanes toll revenue to support additional capacity improvements in the corridor. HPTE and CDOT will continue to evaluate options of financing transportation improvements in this vital corridor.

Central 70 (I-70 East)

I-70 East is Colorado's most critical east-west corridor. More than 1,200 businesses, employing approximately 22,000 people, are located along I-70 East. It is also one of the most congested corridors in the metro area, carrying over 200,000 vehicles every day. After many years of analysis and work with the community, CDOT is in the final stages of completing an environmental study and bringing the first phase project (known as Central 70) to construction.

At the direction of CDOT and the Transportation Commission, HPTE has analyz­ed the benefits, risks and value of various delivery options for the project—including traditional, public-financed models, and several private investment and/or other partnering models. The considerations for private participation include the potential to reduce public sector risk, add innovation to the design, help shorten the construction timeline, and/or add to the project scope to maximize taxpayer dollars. A preliminary Value for Money Analysis (VFM), completed in December 2013, recommended a full design, build, finance, operate and maintain approach, structured as a performance payment concession of no more than 35 years, with CDOT retaining the toll revenues. In August 2015, HPTE recommended using this delivery model for the Phase 1 Project. 

A request for qualifications (RFQ) was issued for the Central 70 project in March 2015 and four teams were shortlisted in July 2015. To date, four drafts of the Request for Proposal (RFP) have been developed, posted and made accessible to both industry and the public.
