Noise Variance Request

Kiewit Meridiam Partners (KMP) has applied for a noise variance to work at night on the Central 70 Project. As with many large construction projects (such as the multiple-year T-REX Project which rebuilt a section of I-25) a noise variance request is a standard step in the pre-construction process. Without approval to conduct night work, impacts to commuters, residents and businesses are extended. Per City ordinance, variance requests are reviewed by the Denver Department of Public Health and Environment and decided upon by the Board of Public Health and Environment. The Board will discuss the KMP variance petition at an upcoming meeting.

In advance of the start of construction on Central 70, CDOT has partnered with the City of Denver to provide home improvements (e.g. insulation, air conditioning units and soundproof windows) to approximately 250 homes. The intent of these improvements is to reduce the impact of construction dust and noise.

Application to close road/railway crossing at 46th Avenue and UPRR railroad tracks


In preparation for construction on the Central 70 Project, CDOT and the City of Denver have filed an application with the Public Utilities Commission to close 46th Avenue between York Street and Brighton Boulevard, to reconstruct the railroad tracks on a new bridge and construct a new roadway. Construction and the closure will start this summer. If you have comments on this closure, please send a letter to the address below. Parties have the right to file written intervention or objection with the Commission at 1560 Broadway, Suite 250, Denver CO 80202. If writing, include Proceeding No. 18A-0293R. All interventions or objection must be filed by no later than June 28, 2018.

Central 70 Project Office


The Central 70 Project Office will be located north of I-70 at Steele/Vasquez. Please watch for crews entering and exiting the work area as they prepare the site.

Construction starts on Central 70 this summer


Construction Schedule

Construction will begin on the Central 70 project this summer. One of the first action items is the closure of 46th Avenue between York Street and Brighton Boulevard, to allow for the construction of a railroad detour (adjacent to Purina, under the I-70 viaduct). Download the graphic.

Soil Testing Started April 2018


Central 70 Project construction crews will conduct soil characterization testing along the 10-mile corridor. The intent of this sampling is to develop a detailed picture of soil types and conditions. This sampling is a critical step in understanding those conditions and allowing the contractor to minimize truck trips in the neighborhood during construction.

Demolition of the Colonial Manor Motel


As part of the Central 70 Project, the demolition of the Colonial Manor Motel is underway. Removal of the motel will accommodate for the widened I-70 and realigned 46th Avenue North. This pre-construction activity is another step toward construction starting this summer on a highway that carries more than 200,000 vehicles per day.

This demolition process, which began in late March, will continue through late-April. Watch for truck traffic on Elizabeth Street and Thompson Court near 46th Avenue.

Financial Close Reached for Central 70


On Dec. 21, 2017 CDOT reached financial close with Kiewit Meridiam Partners. This is the final step in the contract process and sets the terms of the financing for the Project over the contract term. The Central 70 project website includes a complete copy of the contract. Summaries of the financial structure, both over the 4-year construction period and 30-year operation period, are available for download.

Kiewit Meridiam Partners Selected to Build and Operate Central 70 Project

Read the Press Release | Nota de Prensa

CDOT has selected Kiewit Meridiam Partners (KMP) as the preferred proposer to design, build, finance, operate and maintain the Central 70 Project. KMP was chosen from four teams of finalists who submitted proposals for the project in early June.

Preparing for Construction

Selecting a Contractor

In August of 2017, CDOT selected Kiewit Meridiam Partners as the state's partner to design, build, and finance Central 70 as well as operate and maintain the project over a 30-year period. KMP was chosen from four teams of finalists who submitted proposals for the project in early June of 2017.

Finalizing the Contract

In November of 2017 CDOT finalized the contract, with Kiewit Meridiam Partners (KMP), the selected contractor for the Central 70 Project. The contract, also known as the Project Agreement (PA), establishes KMP’s scope of work in delivering the project and details each party’s rights and obligations over the term of the contract. Approval of the PA means that KMP is now officially on board to build Central 70, and the agreement will be in effect until 30 years after construction completion.

The next step is financial close, the stage at which financing is secured. Financial close is expected to occur before the end of January 2018.

The complete, final contract is available here. Given the length and complexity of this document, CDOT has prepared a summary of the project agreement. Additional documents relating to the Central 70 contract and financing are available on the HPTE website.

Homes between 45th and 47th avenues, between Brighton and Colorado boulevards are eligible to receive improvements.

The home improvements were a commitment to the community from CDOT during the 14-year Environmental Impact Statement process and became a requirement in the list of mitigation measures in the Record of Decision the project’s federal approval document. Call 303-757-9413 or email [email protected] to confirm eligibility and get more info.

'duct-work2' a success!

Named Westword’s 2016 Best Urban Art Project, we are building on the success of 'duct-work by presenting ‘duct-work 2! On Friday, Aug. 18, nearly 20 local artists started the process of transforming the viaduct from a beast to a beauty. We partnered with Denver Urban Arts Fund, North Denver Cornerstone Collaborative, Atkins, Xcel Energy and Denver Urban Arts Fund, along with other local sponsors, to fund this community art project and allowed artists to transform the viaduct into something remarkable.

On Saturday, Aug. 26, we wrapped up a week of painting with a community event featuring food from local vendors, the sounds of DJ Beau Sanchez and a community wall for kids to test their urban art skills!

Green Pillars on 46th Avenue

Green Pillar
Have you noticed the green pillars under the I-70 viaduct at Columbine and Clayton streets? These pillars indicate the east-west boundaries of the park that will be part of the Central 70 Project once construction is complete. This 4-acre park will be about 1,000 feet long, and will stretch across the lowered highway just south of Swansea Elementary School. The park will include amenities such as youth soccer fields and a splash park.
