 On March 30, 1954, the Yonge streetcar line closed being replaced by the new Yonge subway starting service that day.Construction of the Yonge subway line started in 1949 and resulted in 28 Yonge streetcar diversions before the subway's opening.Some diversions involved laying temporary streetcar tracks on side streets such as Maitland and Alexander streets so that Yonge cars could divert via Church Street.
