CONCRETE
The use of concrete as a street paving material in the United States dates back to at least the early 1870s in Washington, DC (as documented on historic pavement maps), though the town of Bellefontaine, Ohio, claims to have the "Oldest Concrete Street in America," with Court Avenue, a portion of which was paved with concrete in 1891. Generally free from the destructive force of freeze-thaw cycles that eroded concrete in northern U.S. and Canadian cities, Savannah's concrete streets could very likely date to the early 20th century, with only minor cracking. Concrete was used in Savannah as a street pavement by 1915.
