Please note that this does not mean taking alternative local roads around the closure, rather, stay home as the interstate closure begins at 3 pm.
🚨SUNDAY, MARCH 15 ROAD CLOSURES!🚨Make plans for these closures happening this afternoon. The combination of earlier rain on freezing pavements, heavy snow, and blizzard/whiteout conditions will make many roadways impassable.
🚫2 PM - Saylorville Lake Mile Long Bridge/IA 415
🚫3 PM - I-35 North Ames/U.S. 30 to the Minnesota Border both NB/SB lanes.
Iowa DOT and ISP do not advise travelers to seek alternate non-freeway routes, as these are also likely to be hazardous and have very limited access to shelter and traveler services. Travelers should seek shelter and services in larger cities such as Clear Lake / Mason City, Ames, Des Moines, and Sioux City.
For more information and traveler shelter services and parking, see press release: https://iowadot.gov/news/2026-03-15/iowa-officials-announce-travel-closures-and-advisories-march-15-blizzard
