Watch for wildlife, avoid collisions during daylight saving time

As the sunlight fades during high-volume commutes, Colorado Parks and Wildlife asks drivers to stay alert and share roads with wildlife.
Stay vigilant, drive with caution and slow down.

Changing your clocks with your driving habits during daylight saving time can help prevent wildlife-vehicle collisions. Wildlife experts advise drivers that wildlife is on the move so be aware, drive with caution, and slow down especially at night. 

This Sunday, November 7, 2021, marks the end of daylight saving time in Colorado. This means drivers will set their clocks back an hour, see dusk earlier, and witness more wild animals migrating to their wintering habitats during rush hour traffic on highways. 

As the sunlight fades during high-volume commutes, Colorado Parks and Wildlife asks drivers to stay alert and share roads with wildlife. Autumn is peak seasonal mating and migration for many species, so drivers should watch for wildlife as they begin to experience darker commutes.

The Colorado Department of Transportation also advises motorists to stay vigilant, drive with caution and slow down, as winter storms often push wildlife from the high country into lower elevations.

“We would like to remind everyone that, as the seasons change, deer and elk will be showing up on roadways again,” said CPW Area 18 Wildlife Manager Rachel Sralla. “Keep an eye out for deer moving across roads and follow speed limits to reduce the possibility of colliding with animals. Deer move across our minor arterial roads all the time, and the best way to protect wildlife on the roads is to keep to the speed limit and keep our eyes up.”

“Big game like deer and elk are making their way to the elevations where they can more easily find food and water,” said CDOT Wildlife Program Manager Jeff Peterson. “In Colorado, approximately 4,000 wildlife-vehicle collisions are reported each year. The seasonal movements of these animals can cause increased wildlife-vehicle collisions if drivers are unaware more wildlife is on or near the roadways.”

In an effort to decrease the number of wildlife-vehicle collisions in Colorado, CDOT has collaborated with CPW to develop wildlife prioritization plans for the west slope and the east slope and plains. From these studies, wildlife mitigation projects designed to allow wildlife to safely cross busy highways will be constructed at key segments identified for high risk of wildlife-vehicle collisions. Associated wildlife infrastructure includes wildlife overpasses, underpasses, and high fences with escape ramps and wildlife guards along highways.

Colorado’s Wildlife Crossing Projects

One successful wildlife transportation solution is the Colorado Highway 9 Wildlife Crossing Project. In 2016, CDOT in cooperation with CPW and many other partners completed Colorado’s first-of-its-kind wildlife overpass and underpass system on Highway 9 between Green Mountain Reservoir and Kremmling. This innovative solution to keep wildlife off a busy road resulted in a 90 percent reduction in wildlife-vehicle collisions in that area. Check out the final project video.

With the success of the Highway 9 project, even more crossings are being built around Colorado. To learn more about ongoing collaborative efforts, go to Colorado Wildlife Transportation AllianceSee locations of completed crossings around Colorado at the new statewide wildlife crossing web map. Projects recently completed or under construction include:

  • I-25 Gap Project south of Denver (5 underpasses, high fencing and 1 overpass currently in design)
  • CO 13 Fortification Creek Project north of Craig (1 underpass and a wildlife radar detection system, high fencing)
  • U.S. 160 Dry Creek east of Durango (1 underpass, high fencing)
  • U.S. 160 west of Pagosa Springs (1 underpass, 1 overpass, high fencing)
  • U.S. 550 south of Durango (2 underpasses, several small mammal underpasses, high fencing)

Colorado Parks and Wildlife recently hired Wildlife Movement Coordinator Michelle Cowardin to help coordinate the use of wildlife data to identify highway mitigation projects to protect our wildlife and keep Colorado motorists safe.

“Wildlife crossing structures are a win-win for wildlife and for people. These projects allow animals to move safely across the landscape for seasonal and daily movements while decreasing the risk to motorists of having wildlife collisions. As traffic increases across the state, more roadways will become barriers to wildlife movement, therefore it is important that we work together to develop solutions to maintain healthy wildlife populations in Colorado,” said Cowardin.
