Project-Details

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 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.

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.​​

Schedule

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.​ ​

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.
