On Wednesday, March 1, starting at 9 a.m., the right lane of the bridge will be closed while make deck repairs. The single-lane closure will continue until the repairs have been completed. 360.457.2713 SR 20 traffic will be reduced to one lane at MP 9.8 on Thursday, March 2, during daylight hours while maintenance crews remove dangerous trees. Motorists can expect 5 minute delays. A stop sign has been posted at each end of the bridge to control alternating one-way traffic.
Traffic is on an adjacent detour road while the new bridge is being constructed.
Intermittent traffic disruptions may occur for delivery of materials to the bridge. Work will take place Monday through Friday during daylight hours. Work to install horizontal drains into the hillside to stabilize the slide has been completed. Crews are continuing to maintain the one-lane gravel roadway through the slide area and a temporary signal is in place to control traffic movement. Design work for the second stage of the project, which will restore the highway to two lanes, is under way.
