To address the state’s rapid growth, the Idaho Legislature passed a historic transportation revenue package that Governor Little signed as part of his Leading Idaho initiative in May 2021.

The Legislation transfers $80 million dollars a year to the Idaho Transportation Department’s Transportation Expansion and Congestion Mitigation (TECM) fund. Leveraging these TECM funds as debt service on bond could yield as much as $1.2-$1.6 billion in improvements.

Projects in TECM corridors will accelerate the construction of critical transportation improvements that would otherwise take many years to build, reduce congestion, improve safety and modernize aging roads and bridges across Idaho.
