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 will protect the bridge's steel internal frame and reinforcements from corrosion, maintaining the service life of ​this beloved Portland Historic Landmark.


Traffic Impact

Saturday, June 3-Saturday, June 10

  • Pedestrian detours.

The St. Johns Bridge will remain open and minimal traffic, pedestrian and bicycle impacts are expected during construction. 

Work in Cathedral Park starts October 2022. Please scroll down for visual impacts in Cathedral Park.

The work will require the following impacts for two to three months each:

  • U.S. 30 Bypass (NW Bridge Avenue) at the St. Johns Bridge nighttime lane, shoulder and one bridge sidewalk closure. Flaggers will direct vehicle, bike and foot traffic during closures. One lane of vehicle traffic in each direction will stay open on the bridge, keeping the freight route open.
  • The two N Philadelphia Avenue frontage roads connecting N Syracuse Avenue and N Willamette Avenue will close. The southern frontage road will remain open to local access.
  • U.S. 30 (NW St. Helens Road) westbound lanes under the bridge will shift toward the median and the median width will reduce. Lanes may temporarily close during lane shifts, staging and removal of scaffolding.
  • Temporary sidewalk closures on one side of the bridge at a time. Detour signage will direct people to crosswalks on each end of the bridge. People on bikes can continue to ride in the vehicle travel lane or walk their bikes on the open sidewalk. 
Construction may cause intermittent parking closures near Cathedral Park and the project area. The designated freight route will be maintained and no impacts to river traffic are expected.

Construction Impacts

Cathedral Park Impacts

Work in Cathedral Park starts October 2022. Cathedral Park will remain open during construction. Crews will enclose the active work areas around the bridge pier columns, as well as the east and west anchor houses. Fencing will surround work areas 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. Illustration of the arches and columns under the St. Johns Bridge during construction and after completion.

Visual impacts
Cathedral Park is a popular spot for personal and professional photography. Scaffolding and wrapping will cover the pier columns ​and arches im​pacting views during construction. Construction crews will begin work in Cathedral Park in ​October 2022. More details and information about visual impacts in 2023 and 2024 will be provided before construction begins.​​

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

Construction is anticipated to begin in summer 2022 and continue to spring 2024. Intermittent work will minimize impacts to summer events in Cathedral Park. Construction around the pier columns and arches under the bridge in Cathedral Park are anticipated to begin in October 2022 and continue through January 2024.

We will provide more details and updates about the project throughout construction. Schedule is subject to change due to unforseen weather or site conditions.​ ​



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.​

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.
