Projects planned for the future by Sonoma County Department of Transportation & Public Works.
The existing bridge that carries Chalk Hill Road over Maacama Creek is a one-lane structure built in 1915. It is a County landmark and is eligible for inclusion on the National Register of Historic Places. The existing bridge has deteriorated significantly and is vulnerable to earthquakes as well as foundation scour and erosion along the south creekbank. The bridge has been determined to be unstable in an earthquake, and is threatened by erosion. The County seeks to replace the bridge with a new two-lane bridge.
The Sonoma County Department of Transportation and Public Works (DTPW) proposes to replace the existing Freestone Flat Road Bridge, which is a two-span, steel-girder truss bridge over Salmon Creek, in the southwest portion of the County.
