Cascade Wonderland Highway traffic flow and incidents map - how to use it to check live traffic, road conditions, and weather impacts:
A static map with traffic flow is shown first and to start using the interactive map you press the blue Load button above to go live.
Traffic flow lines:
Red/White dashed lines = Closed Road,
Grey/White dashed lines = Road Work,
Red lines = Heavy traffic flow,
Yellow/Orange lines = Medium flow, and
Green = normal traffic. Black lines or no traffic flow lines could indicate a closed road, but in most cases it means that either there is not enough vehicle flow to register or traffic isn't monitored. Also, if you do not see traffic flow, you can zoom in closer to reveal localized data. If you are unable to pan the map,
press here (to focus off of the map) and try again.
Traffic Incidents: Each icon represents a traffic event or incident such as road construction, closure (red circle with a white dash), or accident. In some regions there may also be live traffic camaras to view.
In known extreme weather events or accidents, the map may still show green lines, even if lanes or the entire road are closed.
