BOISE -- The much-anticipated 8th and Main Tower reached its final structural height Wednesday just after 11 a.m.

The centerpiece of Boise's growing skyline is now about 270 feet tall. The height will increase to 323 feet once its decorative spire is complete.

The 391,930 square-foot tower is under construction to serve as the regional headquarters ofSaltLake City-based Zions Bank and is owned by Utah's Gardner Company.

The final beam of the tower's top deck was lowered into place during a ceremony that included representatives of both Zions Bank and Gardner Company along with Boise Mayor Dave Bieter.

Our crew put a camera on the beam as it was lifted from the ground to its place high above Boise. Click here to see the entire breathtaking video as the beam makes its way almost 300 feet to the top of the building.To watch video on the KTVB app, go to the video tab.

The tower is expected to be completed in January of 2014.

ESI Construction, Zions Bank, and Gardner company lowered the final steel beam into place during Wednesday's ceremonial topping off.


Topping off, or 'topping out' is a tradition among iron workers to celebrate the placement of the final beam at the top of a building. During the ceremony, an evergreen tree is typically placed at one end of the beam and a U.S. flag at the other.

The final beam for the Eighth and Main building was 'topped' by a tree at one end and a flag at the other. The beam was signed by guests who arrived for Thursday's ceremony.

Interestingly, once the tower is completed, the same signed beam will be visible from the top floor mechanical penthouse.

On January 24, 1987, fire destroyed the Eastman Building which had stood for 82 years at the northwest corner of 8th and Main streets. See that story here.

What's more, a failed construction project in 2001 left a huge pit covered in steel rebar on the site. That's because a previous developer's plans to construct a 22-story tower fell through during construction.

Since then, no other permanent building has stood where the Zion's Bank headquarters is now nearing completion.
