SEATTLE — A flat bed semi-trailer rolled over around 7:18 a.m. Tuesday morning, blocking all lanes of traffic in the 4500 block of West Marginal Way.
Police believe a loose container of dry cement the truck was carrying shifted, causing the truck to flip. Seattle Fire medics responded and treated the adult male driver for minor injuries.
The closure is expected to last around two to three hours.
Police closed the roadway and encouraged people to stay away.
