Tassajara Road/Camino Tassajara Road Closure



Beginning May 2, 2016, drivers, bicyclists, and pedestrians will be unable to use Tassajara Road/Camino Tassajara to travel between Dublin and the San Ramon/Danville area, as a portion of the road will be closed in order to replace a failing culvert which runs under Tassajara Road just north of the Fallon Road intersection.  This project, which will likely last until December, will provide greater safety for motorists, and reduce the likelihood of emergency road closures in the future.
