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.
The project utilizes the existing highway system, instead of building from scratch, in order to provide a more immediate solution for congestion along the interstate. CDOT estimates that this innovative approach allows for the I-25 North Express Lanes to be built at less than one-third the original cost and with an estimated $512 million in benefits.
Flatiron Constructors Inc. is the contractor for this project, which is scheduled for completion in October 2015.
To date, the project is 27 percent complete. Work focused mainly on excavation and reconstruction of the shoulder to accommodate the new Express Lane; electrical installation throughout the project; and guardrail placement on southbound I-25. The shoulder is completely paved on northbound I-25 throughout the project, from 84th Avenue to 120th Avenue, and the majority of the southbound I-25 lanes are paved as well.
Posts have been set and installed at two 12-foot-high sound barriers located northbound on I-25 just before 120th Avenue and near 76th Avenue. Panels will be placed on these sound walls in July and August. Sound barriers also will be placed on the northbound side of I-25 near the US 36 interchange.
The next major aspect of the project will begin July 14, when the clearance of the road on I-25 at the 88th Avenue bridge will change. The road below the bridge will be lowered by approximately a foot to meet current clearance standards. This “profile lowering” will be completed by mid-August.
Working Hours and Impacts
Normal working hours are Monday through Friday from 7 a.m. to 4:30 p.m. There will be some night operations for work between Thornton Parkway and 120th Avenue that will require double lane closures.
