CDOT will be installing new curb ramps for pedestrians with disabilities on Castle Pines Parkway at I-25 and five other interchanges to the north.

Motorists using the I-25/Castle Pines Parkway interchange are seeing signs of a statewide effort to improve accessibility for pedestrians with disabilities.

The Colorado Department of Transportation (CDOT) has been installing new curb ramps on Castle Pines Parkway over the interstate in the past weeks, causing lane closures. CDOT will be making the same upgrades to the RidgeGate Parkway, Lincoln Avenue, County Line Road, Dry Creek Road and Orchard Road interchanges through the end of July.

The $1.2 million project will make curb ramps compliant with the Americans with Disabilities Act.

“It has to have an adequate slope to it, be consistent from end to end, and have a uniform slope so it can be used safely by a person in a wheelchair,” said Tamara Rollison, CDOT communications manager. “It’s very important that we do everything we can to make sure these facilities can be used safely by all users.”

Motorists and pedestrians will encounter construction zones on interchange streets only, not I-25. Nighttime work will require on-ramp closures at both RidgeGate Parkway and County Line Road on Saturdays only.

Construction crews from IHC Scott will be working from south to north on the interchanges, and Castle Pines residents should anticipate traffic impacts this month. Work will take place Monday through Friday, and morning start times will vary based on the type of work and the location. The weekday work will begin no earlier than 7 a.m. and end by 5 p.m. in all locations. Construction on sidewalks and medians on Castle Pines Parkway should take a few weeks, but an exact timetable was not available as of press time.

Due to multiple accidents involving pedestrians and motorists, CDOT is also improving lighting statewide to make crosswalks more visible and taking on other “low cost, high impact” projects to keep pedestrians safe, Rollison said.

“Our mission is to make transportation safer and more accessible for all roadway users, including people on bikes, people with disabilities, people who are older and those who may not be able to get around quickly,” she said.
