Work continues this summer on Colorado Highway 13 north of Craig. In 2021, crews constructed a wildlife underpass structure, fencing, and a wildlife detection system in an attempt to reduce collisions between vehicles and wildlife.

Crews work to complete the Colorado Route 13 reconstruction, road widening and wildlife underpass project in northern Moffat County.

The project is on Colorado 13, north of Craig to the Wyoming border, and includes improvements to reduce wildlife-vehicle collisions.

According to the Colorado Department of Transportation, crews will remove the temporary roadway that was laid during the winter shutdown, as crews prepare the road for permanent full-width roadway.



Paving, shouldering, guardrail, final marking, fencing and seeding should all be completed this season.

During the 2021 construction season, crews worked on earthworks and excavation, construction of a wildlife underpass structure, multiple retaining walls, culvert removal and replacement, revetment culvert slip, deep reclamation of existing asphalt, placement of new road base course, asphalt paving, shoulder, fence, guardrail, strip and signage.



In cooperation with Colorado Parks and Wildlife, CDOT designed the project to reduce wildlife collisions while maintaining wildlife movement connectivity, including an arched underpass for wildlife to pass under the freeway, as well as a a section of road that will be equipped with a wildlife radar. detection system.

The detection system will be linked to a warning signal which will activate when an animal is detected entering the roadway.

A tall wildlife exclusion fence will guide animals to the underpass and radar detection area. During the 2022 construction season, crews will install two electrified wildlife deterrent mats (called ZapCrete Mats) on the project adjacent to newly installed livestock guards on Moffat County Routes 38 and 40.

Mats paired with livestock guards replace the use of larger wildlife guards. The ZapCrete wildlife radar detection system and mats are the first of their kind to be installed and tested in Colorado. Upon completion of the project, a study will be conducted to determine the success of the detection system, ZapCrete mats, play ramps and wildlife fence concept.

Motorists can expect a simple alternate trip assisted by a flagman from 7 a.m. to 7 p.m. Monday through Friday. There will also be a 10 foot width restriction in place during working hours.
