VIDEO: WA overpass along I-90 demolished after truck collision

Crews demolished part of an overpass above I-90 in Cle Elum, Washington, after it was struck by a truck carrying an oversized load.

Westbound lanes of I-90 have reopened, but the Bullfrog Road overpass remains closed. Engineers are working to design a new overpass.

The collision happened on Tuesday, Oct. 21, and caused major damage to the underside of the Bullfrog Road overpass. Photos taken by WSDOT show concrete support beams destroyed and tons of rebar pulled free.

By the numbers:

State engineers determined the damage was so extensive that that stretch of the bridge could not be repaired, and would have to be rebuilt.

Washington Gov. Bob Ferguson declared a state of emergency on Thursday, allowing Washington to seek federal funding for the critical work.

WSDOT will provide updates as crews work to replace the now-demolished bridge.
