See I-35 right now — live DOT cameras and real-time conditions along the central corridor, from the Mexican border at Laredo to Duluth on Lake Superior, each tagged with its mile marker. Austin's massive rebuild to Minnesota snow, on one map.
Texas to Minnesota · Laredo to Duluth. Here's what to watch, and where the weather actually bites.
I-35 runs about 1,569 miles from Laredo, Texas to Duluth, Minnesota, crossing six states — Texas, Oklahoma, Kansas, Missouri, Iowa, and Minnesota — and threading through San Antonio, Austin, Dallas–Fort Worth, Oklahoma City, Kansas City, and the Twin Cities.
Austin is the standout: TxDOT's multi-billion-dollar Capital Express rebuild has major sections of I-35 through downtown Austin under active construction, with work expected to continue into the early 2030s. Oklahoma and Kansas sit in Tornado Alley, where spring severe thunderstorms and tornadoes can shut the road down with little warning; Texas and Oklahoma also see occasional ice storms that catch the region underprepared. Iowa and Minnesota bring real winter snow the rest of the way north.
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 the whole way, hands-free on CarPlay and Android Auto.
The live map above shows active closures and incidents along I-35 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 else.
About 1,569 miles from Laredo, Texas to Duluth, Minnesota.
TxDOT's Capital Express project is rebuilding and widening I-35 through Austin in three phases (North, Central, and South), with the Central segment alone priced around $4.5 billion. Work including bridge rebuilds and a drainage tunnel is active now and expected to run into the early 2030s, so expect lane shifts and ramp closures through the metro for years, not months.
Yes — Oklahoma and Kansas are core Tornado Alley territory, with spring severe thunderstorms and tornadoes a real risk, and Texas and Oklahoma both see occasional disruptive ice storms. Track your mile marker through any of it with the MileCheck app.
