View as Map

As snow begins to fall in Seattle, drivers are beginning to ask themselves the most important question of the season. What streets do I need to avoid if I don't want to end up on YouTube looking like a jackass as my car slides down a hill that I shouldn't have been driving down in the first place?

Below you'll find a map of the ten steepest intersections in the Seattle area according to SDOT. If the snow falls hard and sticks to the road, avoid these spots at all costs. Otherwise...see you on YouTube! (And feel free to point out any other danger spots around town in the comments...)
