Know before you go. Whether you're a commuter or a recreational traveler, you need information about the road ahead. By accessing MI Department of Transportation road data, you can view traffic cameras, read alerts about construction and other road-related issues, see snow plows, truck parking, and get stats from weather stations. You can read all those historical markers without getting out of your car! Also available is Google Traffic, just so you have all the data in one app. Be smart, be informed.
