Denver Millennium Bridge, Cable-stayed footbridge in Central Platte Valley District, Denver, United States.

The Denver Millennium Bridge is a pedestrian bridge over railway tracks in Riverfront Park, linking the 16th Street Mall with Commons Park. A single white steel mast, built from cone-shaped plate sections, tilts toward one end and carries cables welded to both sides. Its 6-inch-thick post-tensioned concrete deck spans 130 feet without a steep climb.

Preliminary work on the $9-million footbridge began in 1999. Ove Arup & Partners and ArchitectureDenver designed it, contractor Edward Kraemer & Sons built it with steel fabricated by Colorado Bridge and Iron, and Mayor Wellington Webb opened it on April 22, 2002. A $1-million accessibility and LED lighting renovation began on April 24, 2014.

The name marks both the 2002 opening and Denver's architectural development, as the bridge was opened by Mayor Wellington Webb on April 22, 2002. It links the 16th Street Mall with Commons Park in Riverfront Park, one of three pedestrian bridges between Downtown and the Highland neighborhood.

Visitors can reach the bridge via stairs or glass-enclosed elevator towers at both ends starting from ground level. Since the bridge remains accessible around the clock, you can cross it at any time to move between neighborhoods.

The mast is built from cone-shaped steel plate sections welded into a 3-foot base, 7-foot midsection and 1.5-foot tip. Concrete poured onto the metal deck frame pushed it into place and tensioned the cables, letting the deck be a 6-inch reinforced slab.
