|Origin of name||Sunday, the day of the week|
In 1915, George T. Fleming quipped: "The street directory informs us that Sedgwick street runs from Pennsylvania avenue to Sunday alley. It may be well to state that the terminal was called for the seventh day of the week and not for the Rev. 'Billy.'"
Sunday Alley became Sunday Way in 1914, when a city ordinance changed all alleys to ways.
