OR 34: Van Buren Bridge Project

Construction Phase

Region 2: Willamette Valley and Northwest Oregon (Corvallis, Benton, Linn)

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​This project aims to ensure a safe and earthquake-ready bridge over the Willamette River on eastbound OR 34.​​​​

Banner: Slow down, in the work zone it could save lives. Building a modern transportation system to help Oregon’s communities and economy thrive. During construction, Give yourself more time, try a new way or mode to get there or take a different route.


Traffic Impact

None at this time.

Construction Impacts

We are working on building the temporary detour bridge and work bridge. This work is noisy. We are currently working during the daytime, six days a week Monday through Saturday.

The bike and pedestrian path under the bridge on both the east and west sides are now closed. These paths will be closed for the duration of the project. Alternate routes are marked​

The river channel is marked with buoy lines and signs directing river users where to go.

Online Open House

The construction online open house is LIVE!
Check it out to learn more about construction staging and potential impacts.​

Construction Activities

​Construction noise from pile driving has started and will continue through October as we build the detour and work bridges

Visit TripCheck​ for the most current traffic information.​

​Pedestrians, including those with disabilities, will have access through or around work zones. ​

work zone construction iconPay attention in the work zone, slow down and move over – imagine this is where you work! 

Always drive safely, watch for construction signs and workers. 

Remember: fines double in all Oregon work zones, whether workers and signs are present or not. ​​



​Project Information:

The existing Van Buren Bridge is considered seismically vulnerable, and will be removed and replaced. The bridge is a ​bottleneck​ to travelers and freight as it is narrow, has low clearance, and is currently weight restricted to 12 tons.

The new earthquake ready bridge will be built in the existing location, and will include two eastbound travel lanes, a bike lane, and a protected bicycle and pedestrian path.  There will also be improvements to the intersection of Van Buren Avenue and NW First Street, where a new signal will replace the current flashing yellow pedestrian crossing light.

An Environmental Impact Statement was completed to consider an alternate route for traffic to bypass the central business area of Corvallis.

Previous plans to study bridge options were revived.

An Environmental Baseline Report was completed to help determine requirements for the new Van Buren Bridge. A Bridge and Roadway Alternatives Report was also completed to study design options for locating a new Van Buren Bridge.

Design options included a new bridge parallel to the existing bridge, a curved bridge between the old bridge and the Harrison Street Bridge and a bypass north to connect with OR 99W. No funding was available.

An Existing Traffic Conditions Report was completed and focused on conducting additional traffic studies.

The State Legislature’s passage of House Bill 2017 provided more bridge funding and project planning resumed.

What has been done?

Design and Project Development Activities

  • Design firm contracted and project kicked off in early 2019.​
