Investigators will release more information related to its investigation of a bridge collapse in Washington State last year.
NBCRightNow.com - Investigators with the National Transportation Safety Board will release documents on Wednesday related to its investigation of a bridge collapse in Washington State last year.
The I-5 bridge that crossed over the Skagit River collapsed last Memorial Day weekend when two support structures were struck by a semi-truck carrying an oversized load.
Several vehicles fell into the river, but there were no serious injuries.
Wednesday’s document release will contain facts from reports and interviews, but it will not contain analysis and a probable cause.
Investigators said that will come later this summer when the investigation is complete.
The Department of Transportation opened the new bridge in December and it is named the Trooper Sean M. O’Connell Junior Memorial Bridge in honor of the trooper who died while directing traffic during the collapse on his motorcycle.
Investigators said the bridge was built in 1955 and was "functionally obsolete" because it failed to meet current design standards for lane widths and vertical clearance. They said this could be the major factor in why it collapsed.
