CARMEL, Ind. — It's a no-brainer the City of Carmel is celebrating National Roundabouts Week Sept. 20-25.
With 140 roundabouts — and counting — Carmel has more roundabouts than any city in the United States. In fact, there are only 15 traffic lights remaining in the city.
"It's important for us to recognize this week and celebrate the many positive results of our network of roundabouts, most importantly their safety," said Carmel Mayor Jim Brainard. "We know they are safer, they move traffic more efficiently and they are better for the environment because they drastically reduce emissions from vehicles because less time is spent idling in traffic, waiting for a light to change."
Here's the remaining schedule for the festivities taking place:
