See I-94 right now — live DOT cameras and real-time conditions across the northern tier, from eastern Montana through Wisconsin to Detroit, each tagged with its mile marker. Plains blizzards to Great Lakes snow, on one map.
Montana to Michigan · the northern Great Lakes route. Here's what to watch, and where the weather actually bites.
I-94 runs about 1,585 miles from Billings, Montana across the Dakotas and Minnesota, through Wisconsin and the Chicago area, and into Michigan to Detroit and Port Huron. It's a major freight and commuter route through the Upper Midwest.
The open plains of eastern Montana and the Dakotas bring ground blizzards and wind that close the road with no mountains in sight; from Wisconsin through Michigan, Great Lakes and lake-effect snow are the winter story. Milwaukee, Chicago, and Detroit add heavy metro congestion.
The cameras and alerts above are the before-you-leave view. In the MileCheck app, your exact mile marker and the nearest camera follow you across the plains and the lakes, hands-free on CarPlay and Android Auto.
The live map above shows active closures and incidents along I-94 from the state DOT feeds we cover; a red banner appears at the top if a stretch is fully closed. See the US closures map for everything.
