[2] Supportive tension is created by using the mast as a lever to pull the deck up into a shallow arc, keeping the opposite end of the bridge secured by two steel rods.

Contractor Edward Kraemer & Sons, Inc. implemented the design, subcontracting Colorado Bridge and Iron to fabricate the steel components.

The mast was constructed of cone-shaped steel plate sections welded together to form a 3-foot (1 m) base, 7-foot (2 m) midsection and 1.5-foot (.5 m) tip diameter.

The Millennium Bridge was completed and officially opened by Denver Mayor Wellington Webb on April 22, 2002.

On April 24, 2014, a $1-million renovation began on the footbridge to make the bridge more accessible to pedestrians, along with LED lighting upgrades to improve energy efficiency.
