 During this period, Santa alighted on the steps of the Detroit Institute of Arts to be welcomed by the mayor, then remounted to travel the remainder of the parade route.For a period, the parade route was moved to Second Avenue because electrical wires that powered the Woodward Avenue streetcars posed a hazard to floats and their riders.Streetcars ceased operating on Woodward Avenue in 1956 when the Detroit Department of Street Railways converted to an all-motor-bus fleet.
