A semitruck went over a barrier and off the roadway at the southbound Interstate 5 express lanes near Mercer Street at about 11 a.m. Wednesday, according to the Seattle Fire Department, leading to temporary closures of the express lanes and the Mercer Street onramp to northbound I-5.
The driver had minor injuries, and was able to get out of the truck before emergency responders arrived, according to the Seattle Fire Department. The driver was taken to the hospital in stable condition.
Pictures showed the truck appeared to have crashed into a tree, sending vegetation and large branches onto the lanes below. The truck’s fuel tank was also leaking.
By 3 p.m., the truck’s trailer had been pulled back onto the roadway but the cab was still lodged in vegetation off the roadway.
By 5 p.m., all I-5 ramps to and from Mercer Street had been reopened, and an hour later, all lanes on the highway had been reopened, according to the Washington State Department of Transportation and Washington State Patrol.
Crews from the Washington State Department of Transportation were called in to assess the bridge’s structural stability. The agency said the only structural damage found was minor overhead scrapes and railing that will need to be replaced.
