Interstate 35 reopened around 10 a.m. on March 16, 2026, while Interstate 80 was the last interstate to fully reopen in Iowa after a severe blizzard. Westbound traffic on Interstate 80 from Des Moines to Council Bluffs reopened at 7:30 a.m., followed by the eastbound lanes at 10:30 a.m. The final stretch of Interstate 80, from Altoona to Coralville, reopened at noon.
Despite these reopenings, a blizzard warning remains in effect for a small portion of eastern Iowa, according to the National Weather Service. Drivers are advised to use caution and expect slower drives, as conditions may still be hazardous.
The Iowa Department of Transportation (IDOT) reported that the closure of these interstates came after snow and heavy winds swept through the state on Sunday, creating dangerous road conditions. IDOT noted that these conditions, combined with prior rain, made roadways ‘impassable.’
As of March 16, all state-maintained roads remain open through Des Moines. However, more than 30 counties in Iowa have implemented tow bans, meaning assistance will not be available if a driver goes off the road.
Officials are urging drivers to remain vigilant as they navigate the reopened routes, especially in areas still affected by the blizzard warning. The situation is being monitored closely, and updates will be provided as conditions change.
Travelers should stay informed about weather updates and road conditions before heading out, as the aftermath of the storm may still pose challenges. The Iowa DOT continues to assess the situation and will provide further information as it becomes available.
Details remain unconfirmed regarding the full extent of the impact caused by the blizzard and the effectiveness of the road clearing efforts. Observers expect that ongoing weather conditions may influence travel safety in the coming days.
