Night Work

After 15 years of planning, construction on the Central 70 Project is beginning this month. The Project will include intermittent nighttime work on and adjacent to I-70 from Brighton Boulevard to Chambers Road. Nighttime work must follow specifications set out in a variance recently approved by the Denver Board of Public Health and Environment.

Night work for general construction must stay under certain decibel levels (75 decibels on average/86 decibels peak). Work may occur Monday-Friday 9 p.m. to 7 a.m. and Saturday and Sunday 5 p.m. to 8 a.m.

General construction may not occur in the same residential area for more than five consecutive nights in a 7-day period.

When major construction activities (e.g. bridge demolitions) are scheduled, hotel vouchers will be offered to the eligibility zones. Major construction activities may not occur for more than three consecutive nights.

Night work will begin in the east segment of our Project on Sept 23. Below are the English and Spanish notification that will be distributed to residents in the area beginning early next week. Please do not hesitate to reach out to the team. Connect with us by calling 833-C70-INFO or email us at [email protected]

Notification of Work at Night for Central 70 Project General construction activities will begin the week of Sept. 23, 2018 and continue through the duration of the project. General construction activities will move from location to location throughout the corridor and include, but are not limited to:

  • Maintenance of Traffic (MOT) concrete barrier set/remove
  • Excavation, embankment, and grading work
  • Drainage and utility work
  • Bridge construction
  • Asphalt road surface removal
  • Asphalt road paving
  • Concrete work
  • Concrete road surface removal
  • Concrete road paving
  • Drilled shafts

Work activities will take place between the Colorado Boulevard/I-70 interchange and the Chambers Road/I-70 interchange.

This work is classified as general construction activity and must stay under certain decibel levels (75 decibels on average/86 decibels peak) during the overnight hours of Monday-Friday 9 p.m. to 7 a.m. and Saturday and Sunday 5 p.m. to 8 a.m.

To make a complaint about construction noise during the night call the 24-hour hotline at 833-C70-INFO (270-4636). A noise monitoring technician will be dispatched to the area in question within 30 minutes of the complaint. If noise levels exceed the allowed decibel range, work will be shut down. Residents can decide if they would like a call back with results that night or the following morning. Residents may also call the city at 3-1-1.

The Central 70 team is committed to being a good community partner and will closely monitor noise to ensure requirements are being met.

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 (DDPHE) and decided upon by the Board of Public Health and Environment.

DDPHE will consider input received by Wednesday, August 29th, in its written recommendation to the Board regarding the variance request. The recommendation from DDPHE will be posted on the Department’s website. The Board will also take into consideration all input provided in email/writing up until September 5th at 5 p.m.

Input for DDPHE’s recommendation and comments for the Board on the variance request can be sent via email to [email protected], or sent via regular mail or in-person to: DDPHE Board, 200 West 14th Ave., Suite 300, Denver, CO 80204. Note: All information received will be shared with the Board and is also considered a public record.

The Board of Public Health & Environment will hold a public hearing on Thursday, September 6, 2018 to consider the variance request, and members of the public can attend and provide public comment. For more information about the hearing, please view the Board’s Notice of Public Hearing. For more information on hearings before the Board of Public Health & Environment, please view the Board’s Rules Governing Hearings.

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 to local residents.

Federal Judge rules Central 70 can proceed with Construction

On April 3, U.S. District Court Judge William Martinez ruled that the Central 70 Project can proceed with construction while the case brought against the Project by the Sierra Club et. al. continues through the courts. This decision, along with the recent dismissal of a second lawsuit, confirms CDOT’s long-standing position that the diligence and community-centered focus that led to the Central 70 Project would stand up to the toughest legal scrutiny. While this is not the final step in the legal process, it is an important validation of the work we have done over the last 15 years and will continue to do as we move this important project forward.

 Lawsuit Dismissed

Earlier this month, a lawsuit filed against the Federal Highway Administration in relation to the Central 70 Project was dismissed. The lawsuit claimed that the Central 70 Project was improperly connected to Denver’s Platte to Park Hill stormwater project. The lawsuit, filed in July 2017 by developer Kyle Zeppelin et al., was followed up by an injunction asking the courts to stop both the Denver drainage and Central 70 Project until the suit was settled. In November, the judge denied the request to halt work for either project. A request to reconsider the decision also was denied. In early February, the plaintiffs decided to withdraw their complaint and the lawsuit was dismissed.

This decision is the fourth lawsuit/complaint against the Central 70 Project to be dismissed. There is one lawsuit pending.

CDOT’s Central 70 Project Will Continue to Move Forward

On July 10, CDOT was advised that litigation has been filed in Federal District court in Denver, challenging the January 2017 Record of Decision (ROD) issued by the Federal Highway Administration, which concluded a 14-year-old I-70 East Environmental Impact Statement (EIS) process. Read the press release.

Xcel Energy to Begin Utility Work

Starting Tuesday, May 30, Xcel Energy will begin preparing to move existing overhead utility lines underground before the construction phase of the Central 70 Project. Additionally, Level 3 crews will be working with Xcel Energy to prepare for moving communication lines. This work 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, the conduits will be extended over I-70 on the new bridge and will be connected to the sections that are being placed. The electrical and communication lines will be pulled through and connected. Then, at last, the overhead lines can be removed.

See a map of where this work will be done and where the staging areas will be. Staging areas are needed for crews to stage and store equipment throughout the duration of this work.

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

For more immediate information on the work that Xcel will be performing, please contact Jon Moe at 1-800-895-4999.

FHWA Issues Positive Civil Rights Review of CDOT's I-70 Project

On April 12, 2017, the Federal Highway Administration's Civil Rights Office released the findings of an investigation into CDOT's 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

  • There are 684 businesses within the quarter-mile buffer on each side of I-70 between I-25 and I-270.
  • Approximately 11,408 employees 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.
