SIOUX CITY, Iowa (AP) – A spring storm that brought a mix of rain, sleet and snow is being blamed for numerous crashes and one traffic death in Woodbury County in northwest Iowa.  The Sioux City Journal reports that the fatal crash happened around 4:30 p.m. Thursday on Interstate 29 near Salix, when a northbound vehicle towing a flatbed trailer crossed the median and hit a southbound vehicle. The crash killed a passenger in the northbound vehicle and sent the driver to a Sioux City hospital. Authorities have not released their names.

Woodbury County Sheriff Dave Drew says the biggest contributing factors in Thursday’s crashes were accumulated slush on roads and vehicles going too fast for road conditions.
