See a map of our bridges.

The State of Oregon sets restrictions on vehicle size and weight. Most overdimension permits are issued by Oregon Department of Transportation.

These tables address weight limits by vehicle type. They are based on the condition of the bridge and are updated periodically as bridge conditions change.

Please see ODOT's website for information about permit requirements and to apply for a permit.
