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

Lane and shoulder closures on NW Van Buren Avenue. Eastbound traffic is using the new temporary detour bridge.

Construction Impacts

The temporary detour bridge is open. You can expect:

  • Lane and shoulder closures on NW Van Buren Avenue. The southern lane will remain open while crews are working in the other two lanes. 
  • ​An alternate route for pedestrians while the sidewalk is closed on NW Van Buren Avenue. 
  • A temporary signal at NW Van Buren/1st Street to help direct people whether they drive, walk or roll.
  • NW 1st Street restricted to one way vehicle traffic from NW Van Buren Avenue, for one block in each direction.
  • Restricted driving access to NW Van Buren Avenue from NW 1st Street.
  • No weight restrictions. The detour bridge is open to regular traffic, including semi-trucks, buses and emergency vehicles.

You may see our crews working during the day or night. This work is noisy​. 

Bikes and Pedestrians

The bike and pedestrian path under the bridge on both the east and west sides are closed. These paths will remain closed for the duration of the project. 

The temporary detour bridge includes a separated path shared by pedestrian and bicyclists. This path is now open and is new alternate path to get across the river.

For people biking, walking or rolling from south Corvallis, follow the signed detour to get onto the new path. This detour includes crossing NW Van Buren Avenue at the temporary traffic signal. ​

River Access

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

Construction Activities

We are preparing to build the new bridge. Now we're working on the northwest side of the NW Van Buren Avenue and NW 2nd Street intersection to:

  • Build ADA curb ramps.
  • Install signal pole foundations.
  • Add new drainage structures and pipes.
  • Rebuild the northern two lanes of Van Buren Avenue.

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

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. ​​



Frequently Asked Questions IconThe existing Van Buren Bridge was considered seismically vulnerable, and is being removed and replaced. The bridge was a ​bottleneck​ to travelers and freight as it was narrow, had low clearance, and was weight restricted.

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.​
  • Project development team began design, concept development and public engagement.
  • Right of way phase began in late Summer of 2020.
  • Cultural Resource work started in 2019.
  • Permits, applications, drafts and submittals.​ ​

Where we are at now:

The project is under construction, the contract was awarded to Hamilton Construction.  

We engaged with key interested parties and the community to get feedback on the design of the bridge, to help determine the mitigation measures and to better understand the impacts that would occur during construction. We held in person and online open houses, sent out several community wide postcards and mailers, with project alerts via emails and social media, held one on one meetings with businesses and property owners who will be directly affected by the project, and continue to have on-going conversations with City Staff and community partners during construction.

Past outreach and events:


​Project Development: 2019-2022
Construction started in May 2023 and is estimated to complete in 2026.
Schedules may change as the project constructs.
