Reroute? Not so awesome.... 

Some have suggested that it would be cheaper and easier to entirely move--or reroute-- I-70 onto I-270 and I-76 and replace I-70 with a city street. In addition to the many practical concerns with this idea (see below for impacts on local street traffic), the cost is estimated at around $3.2 billion (nearly triple the cost of the current project).

Traffic Impacts from I-70 Reroute

Today there are 684 businesses within the quarter-mile buffer on each side of I-70 between I-25 and I-270, with approximately 11,408 employees who would lose highway access and be forced to use surface streets if I-70 were rerouted. Rerouting I-70 while leaving 46th Avenue at its current location, encourages highway users needing to access these locations to use 46th Avenue to reach their destinations rather than staying on I-70.

Rerouting I-70 would also force delivery trucks and other large vehicles to use 46th Avenue frequently to reach the industrial areas and businesses near the existing interstate. The resulting high traffic volumes and the truck traffic on 46th Avenue could degrade the quality of the neighborhood and cause safety concerns for neighborhoods, pedestrians, bicyclists, and motorists.

Myths and Facts

There’s a lot of misinformation going around. Download the Fact Sheet to get accurate information on the Central 70 Project.


Throughout the duration of the Central 70 Project, there have been many questions asked from the public and the community. We have compiled some of the most frequently asked questions here

Air Quality

Air quality analysis remains one of the most critical components of the environmental study and is a key concern for local residents, CDOT and the Federal Highway Administration. CDOT must follow the requirements of the Clean Air Act along with guidance from the U.S. Environmental Protection Agency and the Colorado Department of Public Health and Environment.


The Central 70 Project includes a robust and independent drainage system designed to handle a 100-year storm event. Learn more about the drainage plan.

Property Acquisition Process

The Central 70 project requires the acquisition of 56 residential properties and 17 businesses. CDOT is required to follow the requirements of the Uniform Relocation Act for all property acquisitions.

Learn more about Property Acquisition on the I-70 EIS website.
