I-25 modifications impact drivers to and from Castle Pines

Information provided by The Colorado Department of Transportation

The Colorado Department of Transportation (CDOT) has two projects in the works that will directly impact drivers on I-25 between Lincoln Avenue and Dry Creek Road.

Direct Lane Pilot Program

On Monday July 14, CDOT launched a pilot program on southbound I-25 starting near Dry Creek and continuing past Lincoln that created a dedicated direct lane for through traffic to use.

White and black signs and variable message boards continue to reiterate that motorists may not cross the double white lines to enter or exit the direct lane. The Lone Tree Police Department continues enforcement to ensure that drivers do not cross the double white lines that restrict motorists from weaving in and out of the direct lane.

This program aims to improve traffic flow and reduce congestion along the busy I-25 corridor during peak travel times, and the lane is not intended for use by those switching in and out of travel lanes.

The assessment period for the direct lane will continue for several weeks. CDOT will be monitoring traffic flow, traffic patterns, and whether or not this program saves time and increases traffic flow for motorists traveling through this area. CDOT encourages those using this corridor to visit to learn more about the pilot program and to provide feedback on the direct lanes concept and how the lanes are working.

Lane Balance Project

CDOT is scheduled to start a $35 million interstate improvement project, where a section of I-25 from Lincoln Avenue to County Line Road will be widened from six lanes to eight lanes. This is an effort to provide lane balancing and improved interchange ramp connections.

Construction is expected to last approximately two years. Due to the amount of traffic in the area, three lanes of through traffic will be maintained in both directions throughout the duration of the project. However, some night lane closures are anticipated to allow for construction phasing shifts and other fast-track concrete work.

Once complete, this project will not only add additional traffic capacity to the interstate, but will replace existing asphalt with concrete to match much of the I-25 corridor. This project will eliminate the East Frontage Road, create a pedestrian friendly trail connection, and provide ramp improvements to the area.
