Hazard Tree Removal on Idaho Highways

The Idaho Transportation Department would like to share information regarding tree removal along highways in Idaho.

The current tree clearing you may see in various locations along state routes is part of an ongoing hazard tree removal effort as part of our maintenance program to improve safety.

We prioritize removal based on the below safety benefits:

  • Visibility: Clearer sightlines mean drivers can spot wildlife or obstacles sooner.
  • Clear zone: Removing obstacles like trees from the clear zone around highways makes it more likely that any drivers who leave the roadway have a better chance of safely recovering and making it back to the road.
  • Winter driving safety: More sunlight reaches the road surface, reducing icy conditions and the risk of black ice.
  • Roadway safety: Reduces the risk of falling trees on the roadway.
  • Wildfire preparedness: Removing trees near the road creates natural firebreaks that can serve to help slow or stop wildfires.

ITD is not just focusing on tree removal within our own right of way but also proactively engaging other public agency partners, such as the U.S. Forrest Service and Idaho Parks and Recreation, to bring these safety benefits along more of our highways.

In instances where there is a need to address trees on private property we work collaboratively with property owners and get express permission before proceeding with tree removal. We do not remove trees on private land without permission.

It’s also important to understand that not all tree removal you may see along highways is being performed by ITD. Private property owners and timber operations often conduct logging or thinning near roadways, and while we require permits for any work within our right of way that we are not initiating, many of these operations happen entirely on private land.

We understand that Idahoans value our outdoor spaces and the area’s natural beauty. Every decision we make on hazard trees is made with the intent of saving lives.

We’re committed to being transparent about our work and welcome any questions from the public. The public can always reach out directly to ITD for accurate information from district representatives.
