Project Overview

In the summer of 2013, the Colorado Department of Transportation (CDOT) will begin a safety and mobility project on a six-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 Lanes in each direction. This new lane will connect to the existing I-25 Express Lanes to and from downtown Denver. In addition, the project will resurface the existing lanes along this six-mile stretch.

Buses and carpools will be able to use the new lane free of charge, while solo drivers will be required to pay a toll. Toll rates will vary depending upon demand of the lane. The new Express Lane will provide motorists with more reliable transportation options while improving capacity on this congested corridor.

Currently, the project is under design and construction will begin in the summer of 2013 and will be completed in the summer of 2015.
