About Harrisburg, IL

Harrisburg () is a city in and the county seat of Saline County, Illinois, United States. It is located about 55 miles (88.51392 km) southwest of Evansville, Indiana, and 111 mi (179 km) southeast of St. Louis, Missouri. Its 2020 population was 8,219, and the surrounding Harrisburg Township had a population of 10,037, including the city residents. Harrisburg is included in the Illinois–Indiana–Kentucky tri-state area and is the principal city in the Harrisburg micropolitan statistical area with a combined population of 24,913. Located at the concurrency of U.S. Route 45, Illinois Route 13, Illinois Route 145, and Illinois Route 34, Harrisburg is known as the "Gateway to the Shawnee National Forest", and is also known for the Ohio River flood of 1937, the old Crenshaw House (also known as the Old Slave House), the Tuttle Bottoms Monster, prohibition-era gangster Charlie Birger, and the 2012 EF4 tornado. A Cairo and Vincennes Railroad boomtown, the city was one of the leading bituminous coal-mining distribution hubs of the American Midwest between 1900 and 1937. At its peak, Harrisburg's population reached 16,000 by the early 1930s. The city had one of the largest downtown districts in Southern Illinois. The city was the 20th-most populated city in Illinois outside the Chicago metropolitan area and the most-populous city in Southern Illinois outside the Metro East in 1930. However, the city has seen an economic decline due to the decreased demand for high-sulfur coal, the removal of the New York Central railroad, and tributary lowlands leaving much area around the city unfit for growth due to flood risks.
