Seattle television station KIRO got a hold of surveillance video which captures the terrifying images of the May 23 bridge collapse on Interstate 5 just north of Seattle. Officials are still saying it's a miracle that only two vehicles plunged into the Skagit River and only three people were injured, none seriously.
Meanwhile, Debbie Hersman, chair of the National Transportation Safety Board, said the collapse is a wake-up call for the entire nation.
"This is a really significant event and we need to learn from it, not just in Washington but around the country," said Hersman. "At the end of the day it's about preventing an accident like this."
NTSB investigators are expected to take a week to ten days to look at the bridge, talk to the truck driver whose vehicle hit the span, and examining maintenance documents and previous accident reports.
Washington state officials say it will take some time to find short- and long-term fixes for the bridge.
