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 Eby Creek Road from US 6 to Market Street. When construction on this project is completed there will be five roundabouts—two at the I-70 exit ramps, and one each at US6, Chambers Avenue and Market Street—and a new pedestrian bridge over I-70.

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, Colorado, 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 75 percent complete on Phase 1 and includes the completed roundabouts at I-70 on-and off-ramps, the substructure for the pedestrian bridge over I-70 and improving portions of various side roads accessing the corridor.

Phase 2 is 10 percent complete and includes constructing a roundabout at Chambers and Eby Creek, as well as at Market Street and Eby Creek. Crews have switched the traffic pattern to its current state, and are working to complete the pedestrian bridge over I-70. Another piece of this phase is to widen the existing bridge over the Eagle River to allow two full lanes of traffic through the corridor.

In 2013, crews completed the I-70 interchange roundabouts. 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.

Traffic Impacts

Lane shifts are in effect 24 hours a day. The dedicated right turn lane northbound on Eby Creek Road to get to onto Chambers Avenue has been removed. Motorists needing to turn right will turn from the through lane. Additionally, eastbound Chambers Avenue has been reduced to one lane of traffic in each direction.

Motorists can expect delays in their commute through the project. A suggested alternate route for Gypsum residents is to use I-70 to avoid traffic delays in the US 6 and Eby Creek interchange area. Normal work hours will be Monday through Friday from 7 a.m. to 7 p.m. with some night and weekend work.

In late summer, there will be impacts for a few nights on I-70 as crews assemble 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.
