Whether you're traveling on Washington's urban arterials, the highways, or the backroads, it's a good idea to find out about road conditions before you head out. Any number of things can go wrong and mess with the flow of traffic, and they usually do. In the warmer months it can be construction, rock slides, or forest fires. Winter brings icy mountain passes, flooded valleys, mud slides, and avalanches. Any time of year it could be a big concert or sporting event, or an accident or crime scene that impacts transportation on Washington roads.
