Current traffic lane, sidewalk and bike lane closures on Multnomah County bridges
- The City of Portland's SW Naito Parkway Improvements are impacting Hawthorne Bridge traffic through August 2021. The onramp from northbound Naito to Hawthorne Bridge eastbound is closed until this summer. When it reopens a new traffic signal will regulate traffic at the top of the Naito ramp. Access the bridge eastbound from SW 1st and SW Madison St.
- The next construction project that will close traffic lanes on a county bridge is the Morrison Bridge Paint Project, which begins in late summer 2021 and will continue until spring 2023. Several traffic lanes will be closed during this project.
- County Bridge Maintenance crews occasionally close a traffic lane on a bridge during offpeak hours on weekdays or close a bridge on a weekend for maintenance. News releases about these closures are listed on our Bridges home page.
