Idaho Transportation Department Crews Tackle Wildfire Risk by Mowing I-84 Corridor.

Extensive Vegetation Clearance Aims to Prevent Wildfires Along Major Idaho Highway

BOISE, Idaho — The Idaho Transportation Department (ITD) Mountain Home maintenance crew is actively mowing the I-84 shoulders, median, and gores, aiming to mitigate wildfire risks along this heavily trafficked route.

Major Mowing Effort Underway

By the end of the project, the crew will have cleared over 400 miles of vegetation along 64 miles of roadway. Historically, the team stops south of Boise, but with the Bureau of Land Management (BLM) Boise District providing a third tractor, they will extend their efforts up to Gowen Road this year.

Dedicated Team in Action

The four-person team, comprising three operators on mowers and one in a water truck, plans to complete the corridor mowing this week. Their work is crucial in reducing fire fuels along the highway.

Historical Context and Impact

Historical data underscores the importance of these efforts. The late 1900s and early 2000s saw a significant rise in wildfires along the I-84 corridor, often large and challenging to control, marking the area as one of the nation's largest wildfire hotspots.

Strategic Fuel Breaks and Results

In 2013, the BLM Boise District and ITD introduced a comprehensive fuel break strategy along I-84. This included mowing, constructing fuel breaks, and enhancing roadway aprons. These measures, coupled with ongoing fuel reduction efforts, have decreased the average fire size by 95% over the past seven years, even with a 30% increase in traffic flow.
