The track length has been the subject of incorrect discussion over the years. Through aerial photography and research it has been determined that the attraction was never lengthened, but shortened 3 times. On opening day the track was approximately 3,118 feet. The attraction saw its length greatly reduced for the first time in 1974 for the construction of Space Mountain, with the two southern curves being shortened and the entire north portion of the track being reduced, thus shortening the ride to ~2,760 feet. An even larger section was removed to make room for Mickey's Toontown Fair sometime between late 1987 and early 1988, this time the track was reduced to ~2,191 feet. In 2012 the final curve was again shortened to make way for Dumbo the Flying Elephant diminishing the ride to ~2,119 feet. In the end, the current attraction has lost over 32% of its original length.
