A bill for an act relating to the staff sergeant William Nathaniel Howard highway, and including applicability provisions.

HF 2478 designates a 5-mile segment of U.S. Highway 30 within Marshalltown's corporate limits as the "Staff Sergeant William Nathaniel Howard Highway" in honor of an Iowa Army National Guard veteran who died in Syria in 2025. The bill permanently applies this designation to that specific highway segment, regardless of future changes to the highway's federal designation. This is a naming resolution with no new funding or regulatory changes, solely recognizing the veteran through official highway signage.
