Bishop Driscoll, who has headed the statewide diocese since 1999, is 75, the age at which bishops are required by canon law to turn in their resignation to the pope.
Bishop Christensen, 61, has headed the Diocese of Superior since 2007.
The changes were announced Nov. 4 in Washington by Archbishop Carlo Maria Vigano, apostolic nuncio to the United States.
