Xcel Energy to begin Utility Work

Starting Tuesday, May 30, Xcel Energy will begin work to prepare for moving existing overhead utility lines underground. Additionally, Level 3 crews will be working with Xcel Energy to prepare for moving communication lines. This work is being done to prepare for the construction phase of the Central 70 Project and will require crews to dig a trench, work to install conduits and vaults underneath the roadway, cover up the trench, repave the road and move to the next area.

Xcel Energy and Level 3 sub-contractors will be burying conduits (or tubes) underground in a joint trench that will be the future holding space for electrical and communication lines for Xcel Energy and Level 3 Communications. These conduits will remain empty until the new highway is constructed. Once the bridge at Josephine is in place, then the conduits will be extended over I-70 on the new bridge and will be connected to the sections that are currently being placed. The electrical and communication lines will be pulled through and connected. Then, at last, the overhead lines can be removed.

This work will take several months and will include road closures in the affected areas. More details will be provided as the schedule progresses.

Federal Highway Administration (FHWA) Issues Positive Civil Rights Review of CDOT’s I-70 Project

On April 12, 2017, FHWA’s Civil Rights Office released the findings of an investigation into the Colorado Department of Transportation's (CDOT) compliance with Title VI requirements through its study of the I-70 East corridor in north Denver. The investigation found that there is "insufficient evidence that the Project will create adverse, disparate impacts." The finding goes on to state that CDOT has provided a "substantial legitimate justification for its actions and shown that a less discriminatory alternative has not been identified."

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). To see what's included, download the Reroute Fact Sheet

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.

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.

Available Fact Sheets and Information


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.
