Bill Overview
Analyzed Economic Effects
3 provisions identified: 2 benefits, 0 costs, 1 mixed.
Interstate upgrade only if feds protect access
Beginning 07/01/2025, Iowa DOT and the Transportation Commission cannot seek interstate status for the U.S. 65/Iowa 5 segment between I-35 and I-80 unless the U.S. grants a weight-and-size exemption. That exemption must let any vehicle allowed before keep operating after any designation. These rules stay tied to that same physical road even if its name or route number changes. This protects access for trucks, farm equipment, and other users that rely on the segment today.
New bypass route for farm equipment
Beginning 07/01/2025, Iowa DOT works with the Des Moines Area MPO to study and build an alternate route for farm equipment between U.S. 6 and U.S. 69, alongside the U.S. 65/Iowa 5 segment. The goal is a safe, accessible bypass so farm machines do not need to use the interstate segment. This supports safer travel for farmers and other drivers.
Farm equipment can keep using the segment
Beginning 07/01/2025, vehicles that cannot attain and keep 40 mph cannot use any interstate. If the U.S. 65/Iowa 5 segment becomes part of the interstate, farm machines that were allowed there before can keep using the stretch between U.S. 6 and U.S. 69. The DOT can also let them go farther west beyond U.S. 69. This exception ends when a DOT-approved bypass for farm equipment is built, judged suitable with the agriculture department, and opened.
