Ohio needs billions of dollars worth of work on roads, highways and bridges, and a new study says it's becoming a matter of safety in the greater Cincinnati area.The non-profit group TRIP released their findings at the Greater Cincinnati Regional Chamber on Thursday.Watch this story“We know that when roadways are made safer, when we add things like rumble strips, paved shoulders, better intersection design, better lane markings, better lighting, we see safety improve,” TRIP's Rocky Moretti said.The study found Cincinnati had the highest yearly average number of traffic fatalities in the state and the second largest amount of time lost in traffic.The study also found that more than 40 percent of Cincinnati's roads are in mediocre condition -- or worse."It's as if funding for our nation's roads and bridges is stuck at a stop light, and only Congress can make that light turn green," AAA's Cheryl Parker said.TRIP identified $11.6 billion worth of improvements to infrastructure it says are needed across the state, but there's no telling where the money would come from.Members of the chamber said that ultimately, traffic hurts the region's bottom line."We're seeing across the country that the areas that invest in improving the efficiency of their local transportation system also gain the benefit of a more profitable and productive economy," Moretti said.
