One of the world's biggest cranes will soar in the Minneapolis skyline today.

The Terex CC6800 crawler crane is going to be used to hoist the highest, biggest, tallest pieces of the roof on the new Minnesota Multipurpose Stadium.

Mortenson Construction announced testing of the crane will occur multiple times throughout the deay, meaning the boom will be raised and lowered. It's not going to be a common sight because once the crane is tested, it will be raised until its work on the site is done.

The crane is laid out east to west. The best views of its movement are on the north and south sides of the construction site, according to the Minnesota Sports Facilities Authority.

At full height, the crane is almost 400 feet tall and can lift 1,250 metric tons. The crane will be on the site for 15 months.

The $1 billion stadium is going up on the site of the demolished Metrodome, primarily for use by the Minnesota Vikings. The facility is set to open for the 2016 season.
