TECM funding

This project is being funded with Transportation Expansion and Congestion Mitigation (TECM) funds as part of Governor Little’s Leading Idaho initiative. The program allows ITD to accelerate project timelines to address rapid growth and build critical infrastructure today that would otherwise take many years to fund and build.

The I-84 corridor is one of 13 approved TECM corridors in the state. Funding for the construction phases on this corridor will be determined based on project readiness and funding availability.
