An Interstate 5 four-lane bridge over Skagit River, about 55 miles north of Seattle, Washinton collapsed at about 7 p.m. on Thursday evening sending two vehicles were into the chilly water of the river.
Rescue effort by boats and divers saved three injured people and they were taken to the Skagit Valley Hospital and the United General Hospital in Sedro-Woolley.
AP reported that authorities said it appeared nobody was killed.
U.S. National Transportation Safety Board (NSTB) is still investigating the cause of the disaster.
Anyway State Patrol Chief John R. Batiste said a semi-truck driven southbound struck the bridge just before part of it collapsed.
The freeway is a principal corridor for vehicles between Seattle and Vancouver, Canada.
The bridge was built in 1955 and the disaster raised concerns about the safety of old bridges in the United States.
In August 2007, a bridge fell into the Mississippi River in Minnesota, killing thirteen people.
AP reported that more than a quarter of Washington’s 7,840 bridges are considered structurally deficient of functionally obsolete.
