This map from the Louisiana Department of Transportation & Development is a great tool to help you plan your journey, whether it be across town or across the State.
You can see road closures, roadworks, accidents, weather problems and continuously updating traffic cameras. Now you can see how heavy traffic looks before you end unexpectedly sitting in it. This is especially useful now the roads are full of holiday shoppers!
Another useful resource is the City of Baton Rouge Traffic Accident List.
