SAN RAMON, CALIFORNIA – Cyclists, walkers, and runners on the Iron Horse Trail now have a safer way to cross Bollinger Canyon Road. The city officially opened a pedestrian and bike overcrossing on July 19, 2025, giving trail users a car-free path over a busy six-lane road.
Before the bridge, people using the trail had to navigate traffic at street level. The new crossing improves safety, reduces congestion, and makes it easier for residents to bike or walk to work, school, or nearby parks.
The Bollinger Canyon overcrossing is part of the 32-mile Iron Horse Trail, which stretches from Concord to Dublin & Pleasanton. Opened in 2014, the trail is a popular route for walking, running, biking, and even horseback riding. It links homes, schools, parks, and even transit hubs across the East Bay.
Construction on the overcrossing began in spring 2023, after years of planning and community discussion. The sleek cable-stayed bridge spans about 200 feet across Bollinger Canyon Road, creating a continuous, uninterrupted trail through the center of San Ramon.
The project cost roughly $22.7 million, with more than 80 percent of the funding covered by regional and state transportation grants. City officials describe it as one of San Ramon’s most significant safety investments in the past decade, designed to protect trail users while easing traffic flow for drivers below.
The trail is open daily from 5 a.m. to 10 p.m. It’s fully paved, wheelchair accessible and allows leashed dogs. With the new bridge, users can now travel more safely and efficiently, whether commuting or enjoying a weekend stroll.
City officials hope the overcrossing will encourage more residents to bike or walk instead of drive, promoting both healthier lifestyles and a cleaner environment.
