Now that the new Whilamut Passage Bridge is open to traffic, it’s time to dismantle the work bridge and remove it from the river.
The work bridge is the platform that supported the falsework for the arch construction. It also protected the river by catching debris during the demolition of the temporary bridge and allowed crews and equipment to work above the water as they built the new bridge.
Crews have started to remove the northeast side of the work bridge deck, exposing the steel beams and columns that will also be removed.
The work bridge includes 1.3 million board feet of lumber and 15 million pounds of steel. The contractor plans to save the wood and steel for reuse in a future project.
The contractor carefully removes one or two spans of wood and steel each day from the outside portions of the work bridge. This will leave a span about 24 feet wide directly under the northbound bridge.
Finally, crews will remove the remaining center strip before Oct. 31, when the permitted in-water work period comes to a close.
We’re excited to see an unobstructed view of the arches gracing the beautiful Willamette River!
