 The route was established in 1935.Prior to 1969, the western terminus was the same, but the road followed a slightly more southern alignment along Wilson Lane and about to the east, the route turned southeast (now Exchange Road) and ended at 24th Street (then SR-37, now SR-53) just west of its viaduct.In 1965, in order to relieve congestion on the inadequate 24th Street viaduct, the State Road Commission approved funds for the construction of 20th Street between SR-104 west of the railroads (Wilson Lane) and Wall Avenue for the 1968 fiscal year urban program.
