NTSB to release investigative documents on Washington state bridge collapse accident

June 10

As part of its continuing investigation into the collapse of an interstate highway bridge in Washington State last year, the National Transportation Safety Board will open the public accident docket releasing over 2,000 pages of documents on Wednesday, June 11.

On May 23, 2013, at about 7:05 pm PDT, the Interstate 5 bridge that traversed the Skagit River near Mt. Vernon, Washington, collapsed after the support structures were struck by an oversized combination vehicle traveling in the southbound lanes. A sedan and a pickup truck towing a travel-trailer fell into the river; two other vehicles were damaged as a result of the collapse. None of the eight vehicle occupants involved in the collapse were seriously injured.

The documents being released are factual in nature and do not provide any analysis. They include factual reports, interview transcripts, photographs, diagrams and other documents from the investigation. All of these materials will be made available at 10:30 a.m. EDT on Wednesday, June 11 on the following page of the NTSB's website:

Additional material will be added to the docket as it becomes available. Analysis of the accident, along with conclusions and a determination of probable cause, will come when the final report on the investigation is completed this summer.

This will be a document release only; no interviews will be conducted.
