Heavy snow in Washington has caused a lot of beautiful Christmas like bliss. But on the hand, it has caused some mayhem, like most years we Washingtonians see accidents on I-90 when the snow starts to fall and the roads get icy but this year has topped them all. With an accident involving 15 cars. Around 3pm on Sunday they closed the pass to clear the accident before opening it again later that night. They have avoided to give any more detail when describing the accident. For the time being Please avoid taking this route if possible, and if needed chain up for added traction to avoid collisions.
