By the mid-1800s, Ohio's main roads had been much improved. Many had been changed from log roads to plank roads. And many miles had been smoothed and paved with small stones. Between 1900 and 1920, Ohio improved its highway system. Ohio was a leader in the use of concrete to pave streets and roads.The first use of concrete in the United States to pave a street was in Bellefontaine, Ohio in 1891.
