On 24 May 2008 President Thomas S. Monson announced  that there would be a new temple built in Phoenix Arizona. This one will be built in Phoenix, north and west of the Mesa Arizona Temple (1927) and Gilbert, Arizona, announced only a month earlier in April 2008. "Don Evans, Arizona spokesman for the church, said Saturday [May 24, 2008] he hasn’t received details about where or when the church will be constructed." 
Some have reported that it will be at 5212 W. Pinnacle Peak Road, Phoenix AZ Map Growth in this area is such that they are having to expand the I-17 freeway which runs through this area to eight lanes, and talk is of another freeway to parallel that north of the Loop 101, hence the need for a third temple in the Phoenix metro area for the members there.
The temple district may include almost all of Phoenix except for Ahwatukee, northern parts of Scottsdale, and all of the cities on the west side of the valley, plus the Prescott, Verde Valley, and Flagstaff, Arizona areas.
