About the Project

Welcome to the Information Portal for the Bon Air Bridge Replacement Project. This essential safety project is securing the Bon Air Bridge for the next generation of those who live, work, shop, and travel within the City of Larkspur and adjacent communities.

Spanning Corte Madera Creek, Bon Air Bridge is one of the main entrances to the City of Larkspur and is a vital thoroughfare linking Magnolia Avenue, Larkspur’s main street, and the northeast side of the City. Motorists, pedestrians, and bicyclists make thousands of daily trips across the bridge to access businesses, Marin General Hospital and other medical facilities, and the popular multi-use path along the creek.

In the over 50 years since it was built, tidal flows have eroded key components of the bridge. Replacing the bridge is a long-term, cost-effective solution that, in addition to significantly lengthening the bridge’s lifespan, improves access for pedestrians and bicycles and incorporates community-driven design elements. Additionally, related environmental projects within the City limits will improve wildlife habitat and recreational access to Corte Madera Creek.

A Town Hall Meeting was held on May 21, 2015 to share information about the history, purpose, key elements, and upcoming construction milestones for the Bon Air Bridge Replacement Project.
