Do you ever drive across the I-5 bridge? Traffic delays and some closures will begin on Monday, August 17th, and will continue until August 20th in preparation for the Interstate Bridge Trunnion Replacement Project which will close the northbound span of the bridge from September 12-20, 2020.
Crews are building the support system under the bridge’s lift span, preparing the median of I-5 for crossover traffic in September, and installing signage. Nighttime lane closures are Monday, August 17 through Thursday, August 20 on I-5 at the Interstate Bridge in Washington and Oregon. Single lane closures will begin at 8:00 PM and crews could close a second lane at 10:00 PM. All lanes are scheduled to open by 5:00 AM the following morning.
The Interstate Bridge Trunnion Replacement Project will close the northbound span of the bridge from September 12-20, 2020 as crews replace mechanical parts that help lift and lower the bridge. After the nine-day closure, drivers will experience a single lane closure on I-5 south at the Interstate Bridge from September 21–27, 2020 as construction crews remove equipment from the area and wrap up the project.
“During the closure, travelers crossing the Interstate Bridge in both directions will share the three existing lanes and sidewalk on the southbound bridge. A movable concrete barrier will shift the lanes to allow for two lanes of traffic to travel in the heaviest direction during commute times. For example, during the morning commute, the bridge will have two southbound lanes and one northbound lane open. During the evening commute, the bridge will have one southbound lane and two northbound lanes open.
Heavy traffic, congestion and long delays are expected in the region on I-5, I-205, I-84, SR 14 and local streets in north Portland and south Vancouver throughout construction. If travelers do not change their driving habits during the bridge closure, and if traffic levels are at normal levels, the length of back-ups on I-5 may double to 4 miles and the region may experience up to 16 hours of congestion per day.” ~Washington state Department of Transportation
