Skagit collapse papers Did pole strike bridge
The oversize load that struck the Skagit River Bridge was part of an oil drilling rig headed from Alberta, Canada, to Thompson Metal Fab in Vancouver’s Columbia Business Center. The load was to be consolidated with the rest of a barge shipment and shipped to a customer’s site in the far northern oil fields.SEATTLE — A pilot driver escorting an oversize load that triggered an Interstate 5 bridge collapse north of Seattle told investigators that the clearance pole mounted on her car never hit the structure. But in documents released by federal investigators Wednesday, one witness reported seeing the pole strike the Skagit River Bridge several times. The National Transportation Safety Board will have to sort through the conflicting accounts as it determines what likely caused the May 23, 2013, collapse. The agency, expected to release its final report this summer, made public more than 2,000 pages of documents, including interviews, cellphone logs and incident reports.A section of the span fell after a truck carrying a tall load hit the bridge in Mount Vernon, 60 miles north of Seattle. Two other vehicles fell into the river, and three people were rescued with minor injuries. William Scott, who was driving the truck with the tall load, told investigators that a freight truck “came up very fast on the left” and “squeezed me as we were coming to the bridge.” He told investigators that he moved his vehicle to the right, which had a lower vertical clearance than the center lane, the NTSB said.
