While it’s always hoped no one will be killed in Iowa work zones, officials with the Department of Transportation say they’re very encouraged by the latest report on roadway deaths.Mark Bortle, Iowa D-O-T spokesman, says there have only been two fatalities in work zones so far this year, fewer than half the usual number of deaths.The two deaths were reported in Pottawattamie County near Council Bluffs and in Henry County near Mount Pleasant. Bortle says in both cases, the people killed were motorists, not construction workers. Bortle says Iowa motorists really need to pay attention in the work zones.Bortle says Iowa has the 10th largest road system in the nation yet ranks 46th nationally in the ratio of work zone fatalities to total traffic deaths. This year’s numbers are the lowest since 1986 when there was only one work zone death for the year.
