He said the Ohio Department of Transportation has reported roundabouts have led to a 44% reduction in traffic crashes and between 72% and 87% reduction in fatal crashes.
Mark Nolt, a transportation engineer with Kleingers, said they have met with city officials and have completed some traffic counts, finding that there is a significant amount of traffic in the mornings and evenings coming from Interstate 75. A right turn lane might need to be added to the roundabout, he said.
Franklin City Engineer Barry Conway estimated the roundabout to cost about $1.8 million.
The cost for the four-way signalized intersection was $827,346. The city already has been awarded a federal grant of $530,881 and would be responsible for the $296,465 in local costs.
Some school board members were concerned about the costs to the district, as well as traffic backups.
Sander said this was a win-win for the district because if the traffic study says a stop light would be the better alternative, that project already is funded by the city and federal governments.
Board President Andrew Fleming said he thought, “Sander’s recommendation was sound because it lessened the risk.”
“We’re pretty excited about the (roundabout) project,” said Franklin City Manager Jonathan Westendorf. “We think this will be a huge improvement for safety and aesthetics.”
City Council will consider an application to the Ohio Public Works Commission for the roundabout project at its next meeting, Westendorf said. If the city is awarded that grant, Conway said it could cover up to 50% of the costs for the roundabout. He said the application is due next week.
