Interstate Bridge Nine-Day Closure

September 12-20, the northbound span of the Interstate Bridge, connecting Oregon and Washington across the Columbia River on I-5, will be closed so that crews can replace mechanical parts that help lift and lower the bridge.

The bridge will remain open in both directions with north and southbound lanes sharing the three existing lanes and sidewalk (for bike and pedestrian travelers) on the southbound bridge.

A moveable concrete barrier will shift to allow for two lanes of traffic to travel in the heaviest direction during commute times. During the morning commute, there will be two southbound lanes open and one northbound.

For the evening commute, the barrier will be moved to allow two northbound lanes and one southbound.

Four ramps will also close during the bridge closure:

• Marine Drive on-ramp to I-5 north in Portland

• Hayden Island on-ramp to I-5 in Portland

• I-5 North to SR 14 off-ramp in Vancouver

• SR 14/Washington St. on-ramp to I-5 south in Vancouver
