Leaking Chemicals Force Closure of Western Iowa Interstate

Chemicals leaking from a semitrailer forced authorities to close a portion of Interstate 29 in western Iowa.

The Iowa Public Safety Department 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.

A dispatcher says the lanes were reopened around 11 p.m.

The department says the carrier involved was Landstar Transportation Logistics. Landstar is based in Jacksonville, Florida.
