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.

These projects include emergency rockfall repairs recently completed in April 2022 and longer-term rockfall prevention improvements starting in 2023 on NW Bridge Ave. (U.S. 30 Bypass). Construction is underway on U.S. 30 (NW St. Helens Rd.) between NW Bridge Ave. and NW Kittridge Ave. We are repaving the roadway, replacing traffic signals, adjusting vehicle lane widths, building curb ramps to meet Americans with Disabilities Act (ADA) requirements and improving conditions for people biking.

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.
Cost and Funding
Wildish Standard Paving Co.
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.
