Nevada Traveler shows you the current status of major roads and highways throughout the state. By accessing Nevada Department of Transportation road data, you can view traffic cameras, read alerts about construction and other road-related issues, get stats from weather stations. Also available is Google Traffic, just so you have all the data in one app.
All of this is displayed on a map with ease of use for panning and zooming. Only interested in certain areas? You can define your own regions and quickly view them, or use one of the several predefined areas.
