Indian trails played an important role in opening up the Ohio Country to exploration, trade, and settlement. Trails often determined the location of early settlements and military roads. Many of these trails generally followed the high ground between rivers and streams. In northern Ohio, beach ridges created by ancient glacial lakes provided natural paths for east-west travel. Today, some of Ohio's roads and highways follow these old routes.
When Ohio entered the Union in 1803, the state lacked a good transportation system.
In the early 1800s, Ohio's roads were close to towns of some size. By 1820 Columbus was linked with a north-south road and an east-west road, both of which reached the state's borders. Although some areas had good roads, most roads were only improved trails with mud holes and tree stumps.
The best road in Ohio was the National Road. Beginning in Cumberland, Maryland, it had reached Wheeling, Virginia on the Ohio River by 1817. By 1838, it had crossed the state of Ohio.
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.
