I-70 Eagle Interchange Project

Existing Roundabout

Project Overview

CDOT and the Town of Eagle partnered on the I-70 Eagle Interchange project, which began in July 2013, to upgrade the portions of Eby Creek Road and to add a pedestrian bridge over I-70. Five roundabouts—two at the I-70 exits, and one each at US6, Chambers Avenue and Market Street—and a new pedestrian bridge will be constructed by the project’s end.

The project restarted in mid-March and is scheduled for completion by mid-December 2014. All milestones for the first construction season were accomplished on time, prior to a planned two-month suspension of work for winter.

Flatiron Constructors Inc. of Firestone, Colo., was awarded the $15.2 million contract by CDOT. The 15-month project is funded in part by Responsible Acceleration of Maintenance and Partnerships (RAMP) and Colorado FASTER (Funding Advancements for Surface Transportation & Economic Recovery).

Project Benefits

As Eby Creek Road and I-70 access ramps have heavy residential, commercial and commuter traffic, the goal of the project is to improve safety and mobility for both motorists and pedestrians. The improvements are critical to the Eagle community because in the past several years, a large increase in population in the area has created traffic flow issues at the existing interchange, especially during rush hours.

Project Progress

To date, construction is approximately 40 percent complete. The most critical part of this project was completing the I-70 interchange roundabouts in 2013. Completed work also includes concrete paving from Market Street to Chambers Avenue, abutments and piers for the pedestrian bridge, seeding and permanent slope stabilization of on- and off-ramps, installation of new waterlines and storm drainage from Chambers to I-70, installation of new ramp lighting and roundabout lighting and new rail and fence on the bridge over I-70, including new guardrail at the on- and off-ramps.

n this part of the project, crews will work to complete the pedestrian bridge over I-70, construct roundabouts at Chambers Avenue and Market Street, complete reconstruction of Eby Creek Road, widen the US6 roundabout and install new underground utilities from Chambers Avenue to US6.

Traffic Impacts

Motorists can expect additional delays in their commute through the project. A suggested alternate route for Gypsum residents to avoid traffic delays is the US6 Gypsum off-ramp. Normal work hours will be Monday through Friday from 7 a.m. to 7 p.m. with some night and weekend work on waterlines.

In early summer, there will be impacts for a few nights on I-70 as crews prepare and install the pedestrian bridge over the interstate. These impacts are expected to be between 8 p.m. and 6 a.m. and at times will require detours of I-70 Traffic.

Construction hours will be dependent on weather and work load. All business access will be maintained throughout the duration of the project.
