EDMONDS — A semitruck hauling large logs spilled its cargo on the ramp of the Edmonds ferry terminal about 11 a.m. Monday, stranding vehicles aboard the ferry Spokane for several hours.

Service resumed around 2:30 p.m. after logs were removed from the ramp area by a log-loader mounted on a second truck and after an inspection of the ferry dock.

Boats on the Edmonds-Kingston route ceased operating during the delay. The other boat on the route, the Walla Walla, waited at the Kingston dock.

“There are logs and parts of a log truck all the way across that transfer stand, the ramp and on the boat itself,” said Ian Sterling, a Washington State Ferries spokesperson, before the “mess” was untangled.

Sterling said the log removal was a race against time because of the possibility of infrastructure damage from the weight of the logs and the ramp’s movement as the tide shifted.

There were no reports of injuries, and it wasn’t clear how the accident happened. The Spokane was off-loading vehicles in Edmonds after the 10:40 a.m. sailing from Kingston.

Approximately 150 cars and their passengers were stuck on the boat, Sterling said. Walk-on passengers were able to exit immediately, but those who drove on were asked to stay with their vehicles until the logs’ removal.

“Won’t be getting off this ferry soon,” tweeted passenger Michael Galligan, who photographed the scene from the car deck of the Spokane.

Trooper Kevin Fortino with Washington State Patrol said an investigation was ongoing to determine if the driver would receive a citation.

Service disruption planned for Mukilteo

Ferry-goers can also expect closures in Mukilteo and Clinton on Tuesday. Service between the terminals is cancelled as officials prepare for the opening of the new Mukilteo terminal at 5 p.m.

After the 12:15 a.m. sailing from Mukilteo Tuesday morning, crews will begin moving structures from the old terminal to the new location one-third of a mile down the waterfront.

The route will return to the normal schedule with the 5:35 p.m. departure from Clinton, followed by the inaugural sailing from the Mukilteo terminal at 6:10 p.m.
