Chemicals leaking from a semitrailer forced authorities to close a portion of Interstate 29 in western Iowa for around ten hours Sunday.
The Iowa State Patrol says a motorist noticed the leak and flagged down the semi around 12:30 p.m. Sunday in Harrison County.
The leaking liquids were determined to be hazardous, so northbound and southbound lanes were closed and traffic diverted around the closed area.
Hazmat teams were called in.
The liquids were later identified as hydrogen peroxide and other chemicals.
The carrier involved was Landstar Transport Logistics out of Rockford, Illinois.
A dispatcher says the lanes were reopened around 11 p.m. Sunday night.
A chemical leak discovered coming out of a semi trailer om Interstate 29 Sunday afternoon resulted in the highway being shut down in both directions.
The Iowa State Patrol says a motorist flagged down the semi at mile marker 86 around 12:30pm and told the driver they had liquid leaking out of the trailer.
Iowa State Patrol Troopers arrived and the liquid material was deemed hazardous.
Troopers shut down both north and south bound lanes.
North bound traffic was diverted at exit 75 at Missouri Valley and south bound was diverted at exit 112 from Onawa to Nebraska.
Tri-County Hazmat and the Council Bluffs fire Hazmat team responded to the spill and indicated the interstate would be closed for an extended time.
Authorities have not said what the leaking substance was.
