MOUNT VERNON, Washington (AP) — The major link between the U.S. and Canadian sides of the Pacific Northwest region was severed after a bridge collapsed, dumping a handful of vehicles and people into a river, police said. All three people who were on the span were rescued and taken to hospitals.
The four-lane Interstate 5 bridge — more than half a century old — collapsed about halfway between Seattle and Vancouver, British Columbia. It was caused by an oversize truck hitting the span, the Washington State Patrol chief said.
"For reasons unknown at this point in time the semi struck the overhead of the bridge causing the collapse," Chief John Batiste told an overnight news conference.
The truck made it off the bridge and the driver remained at the scene and cooperated with investigators.
The collapse came at the start of one of the busiest holiday weekends of the year in the U.S., Memorial Day weekend. The collapse came before sundown on a clear day. The state Transportation Department said it was investigating whether an oversize truck load may have struck the bridge.
Dan Sligh and his wife were in their pickup truck on Interstate 5 heading to a camping trip when the bridge before them disappeared in a "big puff of dust."
"I hit the brakes and we went off," Sligh told reporters from a hospital, adding he "saw the water approaching ... you hold on as tight as you can."
Sligh, his wife and another man in a different vehicle were dumped into the chilly waters of the Skagit River when the span collapsed Thursday evening. They were injured, but authorities said it appeared nobody was killed in the bridge failure that raised the question about the safety of aging spans.
"We don't think anyone else went into the water," said Marcus Deyerin, a spokesman for the Northwest Washington Incident Management Team. "At this point we're optimistic."
Sligh and his wife were taken to Skagit Valley Hospital with non-life-threatening injuries. The other man was reported in stable condition at United General Hospital in Sedro-Woolley, hospital CEO Greg Reed said.
Authorities are trying to determine what caused the bridge to collapse about 60 miles (100 kilometers) north of Seattle in Skagit County.
State Patrol detectives and the patrol's commercial vehicle enforcement bureau troopers spoke to a commercial truck driver whose rig struck the structure.
Sligh said his shoulder was dislocated in the drop into the water, and he found himself "belly deep in water in the truck." He said he popped his shoulder back in and called out to his wife, who he described as being in shock initially as they waited for rescuers to arrive in boats.
Traffic along the heavily travelled route could be affected for some time.
Jeremiah Thomas, a volunteer firefighter, said he was driving nearby when he glimpsed something out of the corner of his eye and turned to look.
"The bridge just went down, it crashed through the water," he said. "It was really surreal."
The bridge was about 50 feet (15 meters) above the water. Deyerin said it appeared that two vehicles - a car and the pickup with the travel trailer attached - fell into the river. He said the water depth was about 15 feet (4.5 meters), and the vehicles half-visible in the water likely were resting on portions of the collapsed bridge.
Crowds of people lined the river to watch the scene unfold.
"It's not something you see every day," said Jimmy O'Connor, the owner of two local pizza restaurants who was driving on another bridge parallel to the one that collapsed. "People were starting to crawl out of their cars."
He pulled over and saw three vehicles in the water, including the camping trailer that landed upside-down, he said.
The bridge was not classified as structurally deficient, but a Federal Highway Administration database listed it as being "functionally obsolete" — a category meaning that the design is outdated, such as having narrow shoulders and low clearance underneath.
The bridge was built in 1955 and has a sufficiency rating of 57.4 out of 100, according to federal records. That is well below the statewide average rating of 80, according to an Associated Press analysis of federal data, but 759 bridges in the state have a lower sufficiency score.
