Van Buren Bridge Weight Restrictions
As of March 2021, the Van Buren Bridge has been limited to vehicles under 12 tons. This is part of a nationwide load rating review of bridges required by the Federal Highway Administration and is unrelated to the bridge replacement project. It was last assessed for weight restriction in 1995, where depending on how many axles the vehicle had, the max weight was 40 tons.
As part of the new limits, the Oregon Department of Transportation is installing new signs and detours in the area around the bridge, and restriping the bridge to move traffic to the center lane.
