Interstate 35 closed from Ames to Clear Lake and Mason City, including entrance ramps #iatraffic

AMES, Iowa – Feb. 21, 2014 – 1:10 a.m. – The Iowa Department of Transportation, in cooperation with the Iowa State Patrol, has closed northbound and southbound Interstate 35 Ames to Clear Lake and Mason City due to accidents on the roadway. Blowing and drifting snow is preventing tow trucks from being able to clear the area.


The gate system at the U.S. 30/I-35N interchange has been activated and the gate arms are down. Northbound I-35 travelers must exit at U.S. 30. Traveler services are available at the nearby U.S. 30 exits into Ames.  Southbound travelers must exit at U.S. 18. Traveler services are available at the nearby U.S. 18 exits into Clear Lake and Mason City.


In addition to restricting travel on the interstate, all northbound entrance ramps to I-35 in the affected area will be closed by gates. Southbound entrance ramps north of U.S. 20 are also closed by gates.


Travelers already within the closed section will be allowed to exit the roadway. If vehicles are stranded, emergency crews will attempt to assist travelers. Those who have sought shelter in any available rest area facilities will be allowed to remain there, unless directed by Iowa DOT or law enforcement personnel to relocate to another designated safe location.

The decision to close an interstate roadway means a serious safety condition exists and rescue crews may be in the area. You should never attempt to enter a closed roadway or go around barricades or gates.


The Iowa DOT will issue a notification when the roadway is safe and will be reopened.
