Monument Hill Frontage Road Closure

The Monument Hill Frontage Road extended closure is complete. Thank you for your patience.

In August 2020, the Colorado Department of Transportation (CDOT) and contractor partner, Kraemer North America, began major drainage replacement, roadway reconstruction and construction of a new wildlife crossing on Monument Hill Frontage Road as part of the I-25 South Gap project. In addition, crews will install a soundwall between northbound I-25 and the frontage road, from Misty Acres Blvd. near Palmer Ridge High School to the Telios Law building. 

Construction of the wildlife crossing will require a 1,100-foot closure of the Monument Hill Frontage Road for about seven months. This closure will be located between the Colorado Heights Campground access points. Local driveways and business access will be maintained. All construction activities are weather-dependent and subject to change.

The closure began at 5 a.m. on Monday, Aug. 24, and will last into spring 2021.

As one of four wildlife crossings included in the project, this wildlife underpass will help reduce animal-vehicle collisions along the South Gap corridor, and the improved drainage will prevent flooding and soil erosion in this area.
