Benefits
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 concrete repair of its kind 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.
