Mormon temples generally take several years to construct, but circumstances can often extend the period of time between announcement and dedication.
Here are six temples that took longer than 10 years to construct, including two that have been in the works for some time, according to LDSchurchtemples.org:
Salt Lake Temple

Announced July 28, 1847
Dedicated April 6, 1893
Time elapsed: 45 years, 8 months, 9 days
What happened: During the Utah War, from 1857 to 1858, the temple's sandstone foundations were buried in order to hide the construction from potentially hostile federal troops. When construction resumed in 1858, it was discovered that the foundation stones had cracked and needed to be replaced. Additionally, the granite used in the temple's walls was sourced from Little Cottonwood Canyon — approximately 20 miles away from the temple site, leading to an extended construction time.

What happened: Following the temple's announcement, construction was delayed due to problems acquiring the land, World War II and zoning problems.
