AMES, Iowa – MARCH 19, 2025 – 7:30 p.m. –  The Iowa Department of Transportation, in cooperation with the Iowa State Patrol, has reopened north- and southbound Interstate 29 from Sergeant Bluff to Missouri Valley. The roadway was closed mid-morning due to extremely hazardous driving conditions and downed power lines.

The interchange at Port Neal, exit 135, will remain closed overnight until crews can clear nearby downed power lines.

Other Iowa roads in the area remain listed as “travel not advised” or “partially covered.” Wind and freezing conditions can continue to cause roads to be hazardous overnight. In addition, many secondary roadways are still covered with snow or experiencing downed powerlines.

We’re working to get things cleaned up, but the process will be slow. If you can delay your trip, you are encouraged to do so to help crews more quickly and safely clear the roads.
