Caption

A bill for an act relating to certain state highways not designated as part of the interstate road system, including the operation of implements of husbandry on such highways, and including applicability provisions. (Formerly HF 394.) Effective date: 07/01/2025. Applicability date: 07/01/2025.

Summary

HF 1025 limits state action on a specific stretch of highway in central Iowa: the controlled-access segment of U.S. Highway 65 and Iowa Highway 5 between Interstate 35 and Interstate 80. The bill says the Department of Transportation and the State Transportation Commission may not seek an interstate designation for that segment unless the federal government grants an exemption from federal vehicle weight and size rules, and that exemption must allow vehicles currently permitted on the route to keep using it after any designation. The bill also amends Iowa’s rules on interstate travel by slow-moving vehicles, creating a narrow exception for implements of husbandry on the affected U.S. 65/Highway 5 segment if they were already authorized to operate there before any interstate designation. That exception applies to the stretch between U.S. 6 and U.S. 69, with possible extension farther west if the DOT authorizes it, and it is set to expire once an alternative route for farm equipment is developed and opened. In addition, the bill directs DOT to work with the Des Moines Area Metropolitan Planning Organization on an alternative highway study to develop a suitable bypass route for implements of husbandry alongside, rather than on, the affected highway segment. The bill’s practical impact is to preserve existing access for farm machinery and other oversized or slow-moving vehicles on this corridor, while constraining the state’s ability to pursue interstate conversion unless federal law accommodates those vehicles. It affects the Department of Transportation, the State Transportation Commission, the Iowa Code provisions governing interstate-road restrictions, and operators of implements of husbandry who use this route. The overall sentiment appears strongly supportive and largely noncontroversial. The bill passed the House overwhelmingly, 90-2, and the Senate unanimously, 49-0, suggesting broad agreement on protecting agricultural traffic and avoiding disruption to local and regional travel patterns. The available record shows no committee transcript debate, and the narrow dissent in the House likely reflects limited disagreement rather than major opposition. The main point of contention is the tension between interstate designation and continued access for farm equipment. Supporters appear to prioritize maintaining existing agricultural mobility and avoiding a route change that would force implements of husbandry off the corridor, while the bill also leaves open the possibility of future interstate designation if federal exemptions are secured and an alternative bypass is developed.

Impact

HF 1025 adds a new Code section restricting DOT and the Transportation Commission from pursuing interstate designation for the U.S. 65/Iowa 5 corridor unless federal exemptions preserve current vehicle access, and it amends the interstate-road prohibition statute to create a temporary exception for implements of husbandry on that segment. It also directs a study and planning effort for an alternate route and includes applicability language ensuring the bill continues to govern the described highway segment even if its designation changes later.

Sentiment

The bill appears to have enjoyed broad bipartisan support and little visible controversy. It passed the House 90-2 and the Senate 49-0, indicating that legislators generally agreed with the goal of protecting farm equipment access and managing any interstate conversion carefully. The lack of recorded committee debate suggests the measure was viewed as a practical transportation and agriculture fix rather than a divisive policy issue.

Contention

The central issue is whether the affected highway segment should be eligible for interstate designation if that would trigger federal restrictions on slow-moving or oversized vehicles. Supporters of the bill are effectively insisting that agricultural users not lose access to the corridor without a workable alternative route or a federal exemption. Any opposition would likely come from those favoring interstate conversion or concerned about limiting future transportation planning flexibility, but the vote totals suggest those concerns were minor.
