Situated along the 30+ mile Iron Horse Regional Trail, the Bollinger Canyon Road Overcrossing represents a transformative investment in San Ramon’s social and environmental infrastructure, introducing non-motorized circulation, community activation, and placemaking through a landscape-driven design that addresses urban design challenges and mobility complexities in the East Bay suburb. 

This visually compelling urban intervention transforms a post-industrial site with a historic agricultural legacy, integrating a 340-foot cable-stayed bridge into a linear park that engages pedestrians, cyclists, and daily commuters. The project creates a fluid, multi-modal trail ecosystem that is accessible for all, prioritizing non-motorized transportation while offering an uninterrupted, vibrant trail experience. 

Nestled between City Hall, residential neighborhoods, and the renowned commercial center of Bishop Ranch, the 2.5-acre Overcrossing establishes a new model for public open space—one that strengthens social connections, promotes physical activity and well-being, prioritizes safety and accessibility, and celebrates the surrounding California ecology.
