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 on a trip of any length. Check an app or check a website, but either way, stay up to date (apps and websites are listed below).

Any number of things can go wrong and mess with the flow of traffic, and they often do. While you can't change the fact that bigger cities like Seattle are just going to clog up with traffic sometimes, checking ahead helps you plan an alternate route, or at least know what's coming. Beyond traffic, road conditions such as rock slides, forest fires and even construction are not unusual, especially in warmer months. On the flip side, winter brings icy mountain passes, flooded valleys, mudslides, and avalanches.

And 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.

Here are some resources to help you learn about the latest road conditions in Washington state, from travel alerts and sudden changes, to scheduled construction, to mountain pass conditions, to regular run-of-the-mill traffic.

Smart Phone Apps

Nothing beats having access to the latest road conditions from the moment you sit down in your vehicle. These phone apps will give you real-time information.

  • The WSDOT App: You can find the WSDOT app in the Google Play or App Store. It's a handy central resource for the full range of traffic and road conditions in Washington State, including traffic maps, mountain pass reports, ferry wait times and status, border wait times, and toll rates.
  • WAZE: WAZE took the traffic map and elevated it, using real-time traffic updates from other drivers to help you avoid problem spots or find shortcuts. Just be careful using it as using your phone while driving is a ticketable offense in Washington.
  • You can, of course, use Google Maps or Apple Maps (or most other cell phone map apps) and their traffic features as well.
