Attention: Bon Air Bridge Closure Notice
Welcome to the Information Portal for the Bon Air Bridge Replacement Project. This essential safety project, along with associated mitigation projects, will enhance our community 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 local 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.

Mitigation projects stimulated by bridge construction enhance the enjoyment of the natural environment through improvements to recreational facilities at Piper Park, Bon Air Landing Park and at the Marin Rowing Club.
