A bill for an act relating to the installation of transmission lines on highway rights-of-way.

HF 2228 requires Iowa's Department of Transportation (DOT) to coordinate with utility companies upon written request for potential transmission line placements on highway corridors. It mandates the DOT assign a project coordinator within 30 days and share highway project plans that could impact transmission line siting. The bill allows longitudinal transmission lines on primary roads (including interstates) with DOT approval, unless safety or highway function is endangered, and requires the DOT to publicly justify denials within 90 days. This directly affects utility companies seeking to install transmission lines along highways and the DOT's approval process. The bill updates existing coordination requirements to be more structured and responsive.
