Good luck in your effort to save it. If you are able to get photos of the arch, we would be glad to have them on here.

The State Historical Society / State Historic Preservation Officer can provide guidelines. If the bridge is on the National Register of Historic Places, or even NRHP eligible, then replacement will trigger Section 103.

Saving a bridge can be an uphill battle, but it is certainly worth it.

This bridge was built in 1909, not 1925. It was also NOT replaced in 2011. However, the town of Ross is proposing to tear this bridge down and replace it with a modern bridge in 2017-2019, with funding provided by CalTrans. Efforts are being made by the community to stop this from happening, due to the historical engineering of the bridge and it's charm. If you have any information about the history of this bridge, please contact tiffinibanks@comcast.net

Based on the good inspection numbers from 2009 this seems like a bit of a surprise.
