Elections officials report 73,251 ballots were cast between January 31 and Thursday, when early voting ended.
That is three times the number of early votes cast in the last municipal election four years ago.
For those casting absentee ballots, it must be postmarked by Saturday since there is no mail service Monday.
Monday is a federal holiday.
Voters who have not yet received an absentee ballot in the mail can vote in person at the Chicago election board's offices at 69 W. Washington.
ABC7 will have comprehensive election coverage Tuesday night.
Starting with live updates and results throughout Tuesday evening, we'll have expanded coverage on our 10 p.m. newscast.
