The northbound span of the I-5 Bridge will close from September 12–20, 2020 as crews replace mechanical parts that help lift and lower the bridge. The southbound span will remain open to traffic in both directions. The Interstate Bridge is located on I-5 where it connects Oregon and Washington across the Columbia River.
While the biggest traffic impacts happen in September, travelers will experience construction impacts beginning in August, including bridge lifts, lane closures and ramp closures. These impacts will continue through October.
After the nine-day closure, travelers will experience a single lane closure on I-5 south at the Interstate Bridge September 21–27, 2020 as construction crews remove equipment from the area and repair the median barrier. Expect delays traveling into Portland from Vancouver.
I-5 Bridge Closure September 12–20, 2020
During the closure period, travelers crossing the Interstate Bridge in both directions will share the three existing lanes and sidewalk on the southbound bridge. Movable concrete barriers will allow two lanes of traffic to travel in the heaviest direction. Find out more about the bridge and area ramp closures here.
Construction Impacts August–October 2020
The heaviest impacts will occur during the closure of the northbound span of the bridge and the following 7-day lane closure on I-5 south. Travelers will also experience traffic impacts beginning in August and continuing through October.
Nighttime Lane Closures
Periodic nighttime single and double lane closures will occur on I-5 and the Interstate Bridge throughout construction.
Bridge Lifts on I-5 North
