Brothers Circus made an appearance in Harrisburg. In 1913, the Southern Illinois Railway and Power Company operated an interurban trolley line, that ran from downtown Eldorado, into Muddy, Wasson, Beulah Heights, through downtown Harrisburg, Dorrisville, Ledford and into downtown Carrier Mills, all of which had larger residential areas than present. In 1917 there were plans to extend the line westward to Marion and Carbondale to connect to the Coal Belt Co. line, and then run it towards St. Louis. The trolley wire through the county was high. It was an off branch of the Cairo and Vincennes Railroad. The corporation erected the first electrical generating plant in Muddy, Illinois. The Central Illinois Public Service Company purchased the Muddy Power Station in 1916. It had a generating capacity of 7,500 kilowatts. After removing an original 2,500-kilowatt unit, the company added two 5,000-kilowatt turbine-generators and one 10,000 kilowatt unit, bringing the stations total capacity to 25,000 kilowatts in 1922. Electricity generated at the station was distributed over 66-kv, double circuit steel tower transmission lines extending to West Frankfort to the west, the Ohio River to the east, and Olney to the north.

The community benefited from the prosperity of the Roaring Twenties, flaunting the most extravagant displays of wealth in the city's history. The neon red tower belonging to the WEBQ-A.M. radio station was the tallest structure in the city and could be seen for miles.

The eight-story Harrisburg National Bank building, the O'Gara Coal Headquarters, the Cummins Office building, and the four-story Harrisburg Hospital were all built in 1923. The new four-story Harrisburg City Hall building was constructed in 1927, and a complex highway system was constructed through the city, with Illinois Route 13 and Illinois Route 34 constructed in 1918; U.S. Route 45 and Illinois Route 145 constructed in 1925–1926. During this time the city expanded to 15,000 people. The annexation of Dorrisville and Dorris Heights created blue collar, multiple, and single family homes filling in between. On Vine Street south of the town square was "Wiskey Chute", a saloon vice district for local miners. It was also during this time that the town was
