The oversize load that struck the Skagit River Bridge was part of an oil drilling rig headed from Alberta to Thompson Metal Fab, upstream of the Interstate 5 Bridge in Vancouver’s Columbia Business Center. The load was to be consolidated with the rest of a barge shipment and sent down the river and up the Pacific Coast to a customer’s site in the far northern oil fields.
OLYMPIA — The driver of an oversize load that triggered an Interstate 5 bridge collapse told investigators that he felt “crowded” by a passing vehicle and moved closer to the side of the bridge that had less clearance, according to a preliminary federal report released Tuesday.
A brief assessment issued by the National Transportation Safety Board said the oversize load collided with the far right side of the truss structure on the evening of May 23, resulting in the collapse of the bridge into the Skagit River. The driver reported that his load was 15 feet, 9 inches tall while the lowest portion of the bridge braces was just 14 feet, 8 inches.
The NTSB has been looking to speak with the driver of the truck and trailer that passed the oversize load, but board spokesman Peter Knudson said officials still have not found the person or vehicle.
