Lone Tree Bridge

Lone Tree, Colorado78 feet tallCompletion 2018

Design for a new pedestrian bridge involved multiple public presentations and a telephone town meeting with hundreds of Lone Tree residents. Our design approach focused on a symbolic leaf form—the logo of the Lone Tree Arts Center. In addition, we had an aspirational goal to create a landmark that would represent the community’s ambition while acknowledging the site’s grand vista of the nearby Rocky Mountains.

Our vision was to balance steel’s efficiency with artist form. Relying on our experience using cable and pylon geometry, we created a leaf pylon that is essentially a 3-dimensional lattice truss. Constructed of industry standard elements, its geometry is simply twisted to translate stock materials into sculptural form. The 78-foot tall, leaf-shaped mast structure rises on the south side of the long-span, cable-stayed bridge. Six pairs of cables extend down to support the bridge deck. Open mesh sides and a membrane roof protect bridge users and auto traffic below. The bridge connects a city green belt to the south with a northern bike path.
