The new Lone Tree Pedestrian Bridge provides a vital link to the community of Lone Tree, Colorado and creates a major landmark for the City.

As a critical connection for Lone Tree’s pedestrian traffic, the new bridge spans across the rapidly growing city’s busiest thoroughfare. Lincoln Avenue, where over 90,000 cars travel daily, divides Lone Tree Elementary and residential communities on the north from local retail, workplaces, and open space parkland on the south.

The new pedestrian bridge unites the city’s once divided communities with a new symbol of Lone Tree.

Spanning 170 feet in length, the pedestrian bridge allows children from the adjacent elementary school to avoid Lincoln Avenue’s traffic and safely access open space parkland for scientific and ecology education.

The pylon – a signature component of the bridge’s design – is inspired by the City’s leaf emblem. Its form is seen from many vantage points throughout the City, creating a memorable image for Lone Tree.

The core structure of the bridge – an asymmetric cable stay – provides an efficiency of form. In our design, we focused on the sensitivities of the cable and pylon geometry to harmonize steel’s efficiency with an artistic form.

The design team refined the pylon to reflect a leaf while retaining structural integrity.

The main pylon soars 100 feet above Lincoln Avenue, creating a landmark across the City’s skyline as people journey across the bridge and the adjacent greenbelt trail system.

Stainless steel mesh on the sides of the bridge and an ETFE roof protect bridge users from severe weather while enabling one to enjoy open air and sunlight on pleasant days.

The roof is translucent to allow sunlight to illuminate the bridge during the day, and lit gently at night to improve walkway visibility.

Ramps on each end of the bridge facilitate accessible design, multimodal access and connect students, residents, and workers to amenities on both sides.

Lone Tree’s civic pride has been instilled in the new bridge by establishing a memorable landmark in the heart of the community and improved universal access and safety.
