During the 1910s, the Delaware State Fair Association purchased land and built a new fairgrounds within Elsmere's town limit. The grounds, including a racecourse for horses, cars and motorcycles, were located south of New Road and Wilmington Avenue and west of the previously established streets. This land became the site of the Delaware State Fair from 1917 to 1928, and provided a large parking area and ready access from the nearby trolley line. Agricultural exhibits provided the backbone of the fair, but in addition to the races, the summer attraction also included horse and dog shows, vaudeville acts, music, and fireworks. After 1928, the State Fair had moved to Harrington, but the grandstand and the races remained until 1943, when the property was converted to land for residential housing.
