Colorado's Highways Are a Bigger Fire Threat Than You Think

According to the National Park Service, humans are responsible for approximately 85% of wildfires in Colorado and nationwide. When people see a column of smoke rising next to the highway, they usually suspect a lightning strike. Most of the time, the cause is much different.

For Grand Junction drivers traveling on I-70, Highway 50, or Highway 141, the next major wildfire could be caused by chains dragging on the ground or an overheated engine.

Colorado's Highways Are Lined With Ready-To-Burn Vegetation

Why Wildfire Experts Worry About Colorado Highways Every Summer

Anyone who has explored Colorado’s Western Slope knows our highways cut through several sagebrush and pinyon-juniper forests. They also meander through the high desert and grassland areas. Grand Junction, Delta, Unaweep Canyon, the Douglas Pass, and our Grand Mesa all experience hot temps, low humidity, and gusty winds at times. All these ingredients can quickly turn a roadside spark into a fast-moving fire.

The Everyday Vehicle Problems That Can Spark Wildfires

Have you ever driven down I-70 and seen chains dangling from an 18-wheeler? It’s one of the most common ignition sources of fires in Colorado, and the main reason so many wildfires begin near our roads and highways. In addition to chains, a 1000-degree catalytic converter parked over vegetation is also a fire starter. Flat tires, overheated brakes, and mechanical failures have all been linked to roadside wildfires.

Why I-70 Has Become A Major Wildfire Concern

In 2026, Colorado invests millions in roadside vegetation management, tree removal, mowing, and fuel reduction efforts near our highways, especially Interstate 70. We still remember the 2020 Grizzly Creek Fire in Glenwood Canyon, which demonstrated how quickly a roadside fire can shut down a highway. The mudslides that followed proved that the consequences of these fires do not end when the fire is out.
