Rockfall mitigation at MP 67

Two separate rockfall events in 2020 prompted the investigation of the cliff face at MP 67. Although the slope is not unstable, it does act as a chute where rocks gain energy as they come down.

To protect drivers from future falling debris, ITD will update the damaged guardrail, replace the short fence on top of that rail with a taller fence and build a new barrier behind the guardrail.

Leading Idaho

New revenue allowed this project to be advanced from 2024 to 2022.

As part of Governor Brad Little’s “Leading Idaho” initiative, the 2021 Idaho Legislature dedicated $126 million of one-time funds from Idaho’s budget surplus to transportation projects statewide. The funds were split 60/40 between ITD and local jurisdictions. This project is paid for with ITD’s portion of the funds that will accelerate projects to replace bridges, restore pavements, and improve mobility in communities across Idaho.
