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. 

New Weight Restrictions on the Van Buren Bridge

New vehicle designs that distribute weight differently on bridges combined with more traffic overall has led to an update of engineering bridge weight reviews (load ratings) to ensure that our bridges can safely carry everyone to their destinations. Bridge weight restrictions are required when a load rating shows that the structure cannot safely carry standard legal vehicle loads. The bridge is safe to use — as long as vehicles crossing the bridge are under the posted weight limits. Motorists are seeing new weight limits signs on some state, county, and local bridges as new load rating reviews are completed. Take a look below to see some common vehicles and their approximate weights.What does this mean for Corvallis?
