Overweight, Oversize, or Over Dimensional Permits
With the launch of ODOT’s new online over-dimension permitting system, ORION, Marion County will be continuing participation in the over-dimensional program at a limited capacity. Effective May, 2025, Marion County will issue permits for only State and Marion County roads. Please visit Oregon OD Permit Replacement Project website for more information about the project.
