Engineers widened a major road from 30 to 79 feet and dismantled a viaduct before the church, which weighs 741 tons, was moved.

The Kiruna Church is being moved this week along a three-mile route east as part of the town’s relocation. It’s happening because the world’s largest underground iron-ore mine is threatening to swallow the town.

Expansion of iron ore mining forces authorities to clear up buildings in Kiruna, including the 672-tonne Kiruna Church.
