How to use the Lewisville Traffic Map

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 known extreme weather events, flooding, or accidents, the map may still show green lines, even if lanes or the entire road is closed.

Heavy rain and thunderstorms will sweep through the Central U.S. from Sunday through Monday, impacting major routes like Interstate 80 and Interstate 35.

Western Wildfire Risks

Across the West, including regions in Washington and Oregon, watch out for fire weather concerns through Monday due to hot and dry conditions.
