Expect Delays for Work on I-5 Interstate Bridge in Portland Friday Night

Plan ahead Friday night for occasional lifts of the northbound span of the Interstate Bridge while crews grease 1.5 miles of new cable on the lift mechanism.

The Oregon Department of Transportation bridge crew expects as many as eight lifts with each lasting as long as 20 minutes. The lifts will take place between 10:00 p.m. Friday November 20 and 8:00 a.m. Saturday November 21.

The work will have no impact on southbound traffic.

Crews installed the new cable in September on the south tower on the northbound span. That’s when ODOT replaced the trunnion and other parts in the lift mechanism.

The cables help raise and lower the bridge spans. Every year, ODOT crews lubricate by hand more than six miles of cable to keep the lift apparatus on the aging bridge in good operating condition. We expect cable lubrication at the Interstate Bridge will take place again in the summer of 2021.

To avoid delays, travelers can take Interstate 84 east to northbound Interstate 205 over the Glenn Jackson Bridge into Vancouver.

The Interstate Bridge is jointly owned by Oregon and Washington. The northbound span opened in 1917 and the southbound span in 1958. ODOT operates and maintains the bridge.
