ReportWhat the 511 Iowa feed carried over the holiday weekend.
I-80 crosses about 306 miles from Council Bluffs through Des Moines and past Iowa City to the Quad Cities. I-35 runs south to north through Des Moines, where it briefly shares pavement with I-80 on the metro's north side. I-29 follows the Missouri River up the western edge through Sioux City. US-20 crosses the north through Waterloo and Fort Dodge, and US-30, the old Lincoln Highway, parallels I-80 a county to the north.
Iowa's signature hazard is the ground blizzard, clear sky above and zero visibility at windshield height as wind picks the snow up off the fields. When it happens, Iowa DOT closes I-80 and I-35 by mile range and lifts the closure the same way. Freezing rain glazes the I-80 hills east of Des Moines. Iowa DOT also publishes where its plows are, and trucks with a camera send a photo from it.
In October 2026, MileCheck's archive of the 511 Iowa feed held 233 unique reports, including 132 closure reports, 3 crash reports and 98 work-zone reports. The routes with the most reports were I-80, I-380 and I-35. Counts reflect what the feed publishes, so a state whose DOT posts only closures shows only closures. Read the October Highway Report.
The map above shows full closures from the 511 Iowa feed as red markers, crashes in orange, and weather and hazard alerts in blue and purple. Closures the DOT has posted for a future date are listed as scheduled, and ramp and lane closures sit under the toggle so the list stays readable. The page checks MileCheck's feed every five minutes. If the feed cannot be reached the page says so instead of showing an empty map. For the official list, open 511 Iowa.
