With Colorado snowpack lagging and spring already running hot, state road crews are moving fast to keep small spark-and-shoulder fires from turning into highway-closing wildfires.
The Colorado Department of Transportation said Thursday it is stepping up roadside fire mitigation work across the state, accelerating vegetation management and coordinating with state and local partners. The ramp-up comes as a deepening snow drought and an unusually warm spring leave roadside fuels drier than normal and raise the risk of an early, more dangerous 2026 wildfire season.
What CDOT Is Doing
According to the Colorado Department of Transportation, crews will accelerate roadside vegetation management and work more closely with state and local partners to reduce wildfire risk near highways. The agency says it will prioritize high-risk corridors while keeping traffic safety and erosion control front and center.
CDOT's roadside vegetation program includes strategic mowing and trimming, targeted herbicide treatments and reseeding. All of it is meant to cut fuel loads and improve sight lines along highway rights-of-way. That approach is described in guidance from CDOT, which notes that methods and timing vary by corridor to balance safety, habitat and erosion concerns.
Why Officials Are Worried
Federal and state monitors show snowpack and soil moisture running well below average across the Rockies. As outlined by Drought.gov, record-low snow water equivalents and near-record winter warmth have left much of the Intermountain West primed for earlier melt and drier fuels, and Denver Water reports several collection basins are tracking well below median levels.
Fire outlooks are not exactly soothing either. In its March outlook, the National Interagency Fire Center highlights above-normal significant fire potential in parts of the southern Rockies and notes that drought increased across Colorado in recent weeks. The outlook also points out that acres burned so far this year are already well above the 10-year average, a reminder of how quickly conditions can escalate.
The concern along highways is very practical. Vehicle and equipment fires on the shoulder can ignite dry grass and grow into much larger blazes, forcing closures and multi-agency responses. Recent Colorado reporting has flagged worries about unmowed medians on Highway 82 and a vehicle fire that briefly shut parts of Highway 40, showing how a single roadside ignition can trigger a broad emergency response; see reporting from The Aspen Times and Basin Now.
What Drivers Should Know
CDOT says motorists should expect more maintenance crews out and about and occasional lane closures as workers clear fuels. Short holds and reduced speeds may show up on high-risk corridors.
Travelers can sign up for real-time project and travel alerts through COtrip and are advised to give crews room to work and to plan extra time for spring trips.
Clearing roadside fuels will not prevent every wildfire, but transportation and wildfire officials say it can lower the odds that a routine vehicle incident turns into a highway-closing blaze. Keep an eye on official agency channels and plan as Colorado moves into what experts say could be a risky 2026 fire season.
