Construction on a distinct new pedestrian bridge kicked off in Lone Tree, Colorado, on Sept. 29. Thornton Tomasetti is providing structural design and engineering services to Fentress Architects for the project, which will give the city as well as Denver’s metropolitan area a new landmark structure. The bridge will allow walkers, joggers and bicyclists to cross busy Lincoln Avenue, which sees up to 89,000 vehicles daily, without interfering with traffic flow. Spanning 170 feet, the cable-stayed bridge will feature a large, leaf-shaped mast on its south end that will rise 78 feet. Six pairs of cables will extend from the leaf to support the bridge. The cable-stay structure is a highly efficient design that will reduce the weight of the bridge as well as the amount of materials and costs involved in its construction. A translucent ETFE roof will allow sunlight to pass through while providing protection from the elements. Lighting will illuminate the roof at night. The architectural and structural design of the bridge will minimize nighttime closures of the avenue during construction, which is scheduled for completion in spring 2017.
