Project Overview

Overview

In October 2013, the Colorado Department of Transportation (CDOT) began a safety and mobility project on a 6-mile segment of I-25 between US 36 and 120th Avenue. The project will maximize the use of the existing highway infrastructure to expand the capacity of I-25 by adding one HOV/tolled Express Lane in each direction. In addition, the project will resurface the existing lanes along this 6-mile stretch.

The new Express Lanes will connect directly with the existing I-25 Express Lanes leading into and out of downtown Denver, providing motorists with the option of carpooling or paying a toll for a more reliable commute, or utilizing the existing general purpose lanes for free.

Flatiron Constructors Inc. is the contractor for this project, which is scheduled for completion in October 2015.

Progress

To date, the project is 35 percent complete. The northbound shoulder on I-25 is completely paved throughout the project, and just 3,000 feet of the southbound shoulder on I-25 is left to reconstruct and pave. Shoulder work will be completed by late October.

Work on the profile lowering at the 88th Avenue Bridge was completed in August. The road below the bridge was lowered by approximately one foot and now meets current clearance standards. As part of the work at 88th Avenue, the RTD bus lane and ramp was reconstructed and widened.

The sound wall on northbound I-25 near 120th Avenue is 95 percent complete, and by the end of this current phase, sound walls will be complete on northbound I-25 near 76th Avenue and south of 84th Avenue. In October and November, crews will continue work on two walls on southbound I-25 between 120th Avenue and 84th Avenue.

Upcoming work includes installation of a new drainage system and continued work on the HOV lanes toward the southern end of the project limits. Traffic will shift to the newly reconstructed shoulders while construction moves into Phase 3, when the team will work on the inner lanes of I-25.

Working Hours and Impacts

Normal working hours are Monday through Friday from 7 a.m. to 4:30 p.m., and no lanes will be closed during the day. Night work, requiring double lane closures, will take place from 10 p.m. to 5:30 a.m. Some weekend work will take place as needed.
