Transportation officials are warning of jammed roads, crowded buses and full trains when the Alaskan Way Viaduct closes permanently on Friday, Jan. 11, and the new Highway 99 replacement tunnel doesn’t open for another three weeks, as construction crews connect existing roads to the tunnel.

Government agencies and private businesses have a number of resources to help you find the quickest route — or at least avoid the worse one — as you move around town.

For drivers

  • Seattle Department of Transportation (SDOT) has a website called Seattle Traffic with up-to-date traffic conditions, maps for trip planning and information about the viaduct closure and the new tunnel. SDOT’s travelers information map has links to traffic cameras and construction updates.
  • Another SDOT web page called Construction Look Ahead lets you sign up for notices sent directly to your email with details about road closures and major events that may cause delays.
  • SDOT provides email traffic alerts twice per day — once in the morning, and once in the evening — with information on travel times, tips and commute suggestions customized for your neighborhood.
  • The Washington State Department of Transportation (WSDOT) offers personalized updates about your commute. You can sign up for email and text-message alerts, or download the agency’s app.
  • WSDOT also provides updated travel times and live traffic cameras that monitor major roads.
  • A slew of navigation apps can help drivers get around the region. Some of the most popular are Waze, Apple Maps, Google Maps (you can download the version for Android and iOS) and MapQuest (here’s the version for iOS and for Android).
  • Kitsap Transit has created a web page for all resources related to the viaduct closure.
  • Having trouble finding parking? Try Garage Hop, a parking app that connects people looking for parking with residential buildings that have spaces to spare. And information about Park & Ride locations is available here.
  • Need to pay for on-street city parking? Download the PayByPhone app.
Traffic Lab is a Seattle Times project that digs into the region’s thorny transportation issues, spotlights promising approaches to easing gridlock, and helps readers find the best ways to get around. It is funded with the help of community sponsors Alaska Airlines, CenturyLink, Kemper Development Co., NHL Seattle, PEMCO Mutual Insurance Company and Seattle Children’s hospital. Seattle Times editors and reporters operate independently of our funders and maintain editorial control over Traffic Lab content.
