Live Coverage Skagit River Bridge Collapse 2 Remaining People RemovedA portion of an interstate highway bridge in Washington state collapsed Thursday night, sending cars and people into the water, authorities said. The collapse occurred on the Interstate 5 freeway over the Skagit River in Mount Vernon, Wash., about two hours north of Seattle. It was unclear whether or not there were any injuries. "N/B and S/B lanes of I-5 Skagit River Bridge collapsed," Washington State Trooper Mark Francis posted on Twitter. "People and cars in water." MOUNT VERNON, Wash. May 24, 2013 (AP) An Interstate 5 bridge over a river north of Seattle collapsed Thursday evening, dumping vehicles and people into the water, the Washington State Patrol said. The four-lane bridge over the Skagit River collapsed about 7 p.m., Trooper Mark Francis said. There was no immediate estimate of how many people were in the water or whether there were any injuries or deaths, he said. It also was not known what caused the collapse of the bridge about 60 miles north of Seattle in Skagit County, which stretches from the North Cascades National Park to a cluster of islands off the Washington coast. Xavier Grospe, 62, who lives near the river, said he could see three cars with what appeared to be one person per vehicle. The vehicles were sitting still in the water, partially submerged and partly above the waterline, and the apparent drivers were sitting either on top of the vehicles or on the edge of open windows. "It doesn't look like anybody's in danger right now," Grospe said. Crowds of people lined the river to watch the scene unfold, The Skagit-Valley Herald reported. Washington state was given a C in the American Society of Civil Engineers' 2013 infrastructure report card and a C- when it came to the state's bridges. The group said more than a quarter of Washington's 7,840 bridges are considered structurally deficient of functionally obsolete.2013-05-24T04:23:54.000Z

Yesterday, the Interstate 5 Bridge over the Skagit River in Washington state collapsed, sending cars and people into the water.

As you can see from the shocking footage above and images below, both the northbound and southbound lanes on the bridge were affected.

According to the Huffington Post, the bridge spans 1,111 feet and is located 60 miles north of Seattle. Shockingly, a member of the Washington State Department didn’t know when the bridge was last inspected and said “All of our bridges in the area are pretty old.”

Luckily no one was killed, but three people were injured in the incident.
