Description 

This Scherzer rolling lift bridge was built across Sonoma Creek near the San Pablo Bay. (The slough is only a couple feet deep and dwindles rapidly upstreeam of the bridge, so I'm not sure why they bothered with a lift bridge.) This brigde is manually raised by pulling a chain. Nautical charts still list it as openable and hand chalked dates on the counterweight suggest it was opened as recently at 2007.

@ Jann, it turns out that Millerick Rd is open and legal, past the Larsen family winery and down to a locked gate in the vineyards with a small parking lot. It is then a mile plus hike across to the bridge. I met one local at the time of my visit who had driven in from the West on the private entrance road. Yes, I have know of this bridge for several years and figured i would never find a way to approach the location. One of my current favorite unusual locations.

Great photos, Craig! How did you get to the bridge - I wasn't sure if any of those roads were open to the public?
