The Idaho Association of Highway Districts (IAHD) is a nonprofit, nonpartisan service organization dedicated to the improvement of highway districts. The Association was designed with the objectives to oversee legislation affecting Idaho's 63 highway districts; educate highway district officials to continually improve management policies and practices; and assist members to find or obtain technical and legal services. Our mission is to be a strong, well-respected, financially stable, visible association with a unified voice that promotes the interests of Highway Districts.
