TDOT offers travel app
Before you hit the road, if you're traveling in Tennessee, you may want to download the SmartWay app.
It's a navigation tool from the Tennessee Department of Transportation.
The app will help you plan your route and shows how fast traffic is moving, crashes, where those construction barriers are still up and road conditions.
You can also customize it to your trip.
The app is free for iPhone and Android users. For more information visit www.tdot.state.tn.us/tdotsmartway/mobile.htm.
