See I-75 right now — live DOT cameras and real-time conditions along one of the great north–south routes, from South Florida to northern Michigan, each tagged with its mile marker. Atlanta traffic to Great Lakes snow, on one map.
Florida to Michigan · Miami to the Upper Great Lakes. Here's what to watch, and where the weather actually bites.
I-75 runs about 1,786 miles from Miami and Naples up through Georgia and Atlanta, across the Tennessee and Kentucky mountains, into Ohio and Michigan and on to the Upper Peninsula. In Florida it includes "Alligator Alley," the long straight run across the Everglades.
Congestion dominates the metro stretches — Atlanta's I-75 is among the busiest in the Southeast, and Detroit's is heavy too. Weather-wise, the northern end sees Great Lakes snow through Ohio and Michigan, while Florida brings summer thunderstorms, fog, and hurricanes.
The live map above shows active closures and incidents along I-75 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.
