St. Johns Bridge Repair Project

Construction Phase

Region 1: Portland metro and Hood River County (Portland, Multnomah)

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​We are improving the long-term safety and lifespan of the St. J​​ohns Bridge by repairing the concrete on the pier columns and arches under the bridge. Repairing the concrete protects the bridge's steel internal frame and reinforcements from corrosion, maintaining the service life of ​this beloved Portland Historic Landmark.


Traffic Impact

  • Pedestrian detours.

The St. Johns Bridge will remain open and minimal traffic, pedestrian and bicycle impacts are expected as construction nears completion in summer 2024.​ ​

Construction Impacts

Cathedral Park Impacts
The concrete on the piers required more work than originally planned. This increased the cost of the restoration work on the piers. We eliminated the repairs of remaining piers from the project scope to stay within the established project budget. There is the possibility of future concrete repair work on the pier columns as a part of a separate project. 

Project work in Cathedral Park started in October 2022 and ends in summer 2024. Cathedral Park remains open during construction. Crews enclose active work areas around the bridge columns with fencing in the park. These areas will close to park users.

The safety of our workers, park users, and travelers is our highest priority. Detours and flaggers may direct people in the park away from work areas. Pathways near pier columns in the park may temporarily close during construction. Park users may hear noise during the day or see construction equipment.

Intermittent work will minimize impacts to summer events in Cathedral Park.

Visual impacts
Scaffolding exampleCathedral Park is a popular spot for personal and professional photography. Scaffolding and wrapping covers columns ​and arches while work is occurring, impacting views under the St. Johns Bridge in Cathedral Park during construction. Work to repair more than half of the bridge pier columns in Cathedral Park is near complete. 

Wedding impacts
Per Portland Parks and Recreation, wedding permits for the Cathedral Park Staircase and Deck are not available as of October 1, 2022 for the safety of our crews and park users. A simple wedding ceremony consisting of no more than the couple, officiant, and two witnesses is allowed​ on a first-come, first-served basis, as bridge repair work allows. The Cathedral Park Amphitheater is available for reservations as usual. Learn more at

One pier is currently under repair. We anticipate project completion in summer 2024.

The concrete on several of the piers required more work than originally planned. This increased the cost and time required to do the project work. We have eliminated repairs of a few remaining piers that were in better condition. This allows us to stay within budget and complete work in the park in summer 2024. There could be future projects to repair concrete on the remaining pier columns that were not restored during this cycle.

Built in 1931, the St. Johns Bridge is a registered Portland Historical Landmark that serves diverse local and regional travelers. More than 22,000 vehicles cross the bridge each day. It is also a popular bike and transit route and is a designated freight route.​

This project follows maintenance work to the steel frame recently completed in 2019.​

U.S. 30BY |

​The St. Johns Bridge spans the Willamette River connecting Northwest and North Portland. Work will happen on the pier columns and anchor houses under the bridge on both sides of the river, the railing on the east side of the bridge, U.S 30 Bypass (NW Bridge Avenue), and the two N Philadelphia Avenue frontage roads. Cathedral Park is located under the bridge on the eastside.

We’re improving the long-term safety and lifespan of the St. Johns Bridge by repairing the concrete on the pier columns and arches under the bridge.​ Repairing the concrete will protect the bridge’s steel internal frame and reinforcements from corrosion, maintaining the service life of this beloved Portland Historic Landmark.

What Problem Will This Improve?

This is the first comprehensive concrete repair since the bridge was built in 1931. After 90 years, the concrete is chipping away and exposing the internal steel frame inside the pier columns.
