Update at 3:33 p.m.: All lanes of northbound Interstate 5 at Boeing Field have been reopened.
Update at 2:14 p.m.: The truck is upright. All lanes of northbound I-5 are still blocked, according to WSDOT and Washington State Patrol tweets.
Update at 1:47 p.m.: A DOT work crew tried to lift the trailer upright, but the roof broke off and spilled pallets that were inside.
Crews are now going to use a forklift to unload the pallets and boxes. The process will likely take some time. Meantime, three lanes remain blocked.
Update at 1:55 p.m.: All lanes are closed on northbound I-5 near Boeing Field as crews work to upright the overturned semi, according to tweets from the WSDOT. Use alternate routes.
Update at 12:10 p.m.: There’s no word yet on what caused a semi to overturn around 11:40 a.m. Wednesday, but a spokesman for the Washington State Patrol warned drivers to expect delays on northbound Interstate 5 near Boeing Field for at least the next few hours as crews work to clear the scene.
“I’m not sure what their strategy is yet,” but tow trucks are en route to the crash site, which continues to block the two left lanes of the freeway, said Trooper Chris Webb. Just after noon Wednesday, Webb said the far right lane was open to traffic and a second lane was expected to open soon, but drivers can expect intermittent delays as the truck is righted and removed from the scene.
“It’ll be a long-term deal for at least a few hours,” he said.
It appears that only the semi was involved in the crash and that nothing from the vehicle, which Webb described as a container truck, spilled onto the roadway.
Original post: A semi-truck overturned on Interstate 5 near Boeing Field, blocking all lanes northbound Wednesday morning.
A crew from the state Department of Transportation was able to push the overturned semi out of most of the lanes to allow traffic to move by on a single lane. However, traffic is backed up at the scene.
Kyle Moore, a spokesman for the Seattle Fire Department, said no one was trapped by the crash and one person was transported to a hospital with minor injuries, he said.
