We are 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.
Minimal traffic impacts are expected. The St. Johns Bridge will remain open to all travelers during construction. Cathedral Park will also remain open, but some park impacts are expected. Construction is anticipated to begin in late spring 2022 and continue to spring 2024.
We will provide more details and updates about the project throughout
construction.

Traffic Impacts
The St. Johns Bridge will remain open and minimal traffic, pedestrian and bicycle impacts are expected during construction.
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 signs 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.
Project Area
Impacts to Cathedral Park
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.

Visual Impacts
Cathedral Park is a popular spot for personal and professional photography. Scaffolding and wrapping will cover the pier columns and arches impacting 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.
