2271 - Comparative Assessment of the Current Gross and Axle Truck Weight and Truck Permitting Laws in the United States

The Governor of Oklahoma signed Senate Bill 638 that raises the legal truck weight limits under certain conditions. Under the law, and by annual purchase of a permit, the gross weight limit on the non-interstate highway system is increased by nominally five percent (5%) and individual axle weight limit is increased eight percent (8%). The Oklahoma Department of Transportation (ODOT) Senior Staff requires information regarding the impact of the increase in legal load limits on the Highway Infrastructure. Chief among their concerns are the impact of increased truck weight limits on the existing highway infrastructure, and what the costs to new projects, rehabilitation projects, and maintenance will be. There are also questions about what policies are in force in the contiguous United States with particular emphasis on the states adjacent to Oklahoma. The proposed investigation will respond to the needs of the ODOT Senior Staff by providing key answers to these concerns.
