The Denver Millennium Bridge is the world’s first cable-stayed bridge using post-tensioned structural construction. Its 200-foot (61m) white tapered steel mast rises above Denver’s northwestern skyline, connected to the bridge deck and foundation anchors by steel cables. This unique footbridge crosses railroad tracks and the regional light rail system, climbing no higher than 25 feet (8m) above street level, thereby minimizing the height pedestrians must climb. Located near LoDo (Denver’s lower downtown), the Millennium Bridge connects the popular 16th Street Mall with the Commons Park in the Central Platte Valley District of the Union Station neighborhood. The bridge is the first of three pedestrian bridges between Downtown Denver and the Highland neighborhood.
