http://www.adamsamigos.net/mosquito/dvdrive.htm came across a photo there. I believe this is of the old bridge at the same location but I could be mistaken (it's certainly in the same area). What I find particularly interesting is the 3 vertically separated cables.

I stopped by on a ride yesterday. Holy crap the bridge moves a lot when cars/trucks drive over it, I sure wouldn't be willing to drive something that weighed 5 tons (the limit) over it.

People are also dumb and drive over it before the previous vehicle is off. I don't think there are signs saying not to, but still...

400 feet sounds like the replacement bridge, yet the article also seems to indicate the current bridge is 150 years old. Sounds like sloppy reporting

Two thoughts"

1)Now someone can make an entry for the Old Mosquito Road Bridge.

2) The Mt. Democrat story said the new bridge was 400 feet above the river. The bridge in this entry is nothing like that high.

The bridge in the postcard photo is probably the pre-1939 bridge. It looks markedly different than the current one.

https://www.mtdemocrat.com/news/mosquito-road-bridge-given-t... has info about a replacement, including:

"Located 400 feet above the river, it will replace the existing Mosquito Road Bridge that was built 150 years ago."

https://www.edcgov.us/Government/dot/Bridge%20Projects/Mosqu... states that it was built in the 1800s, possibly 1859. It also states that there was a new bridge built in 1939, so I suppose 1939 might be accurate - I guess it depends on whether it was rebuilt or fully replaced.

https://www.edcgov.us/mosquitobridge has more info on the replacement.

Is 1939 accurate? I found a photo (credit there was to the California State Library) claiming to be from 1914. I'm sure it's been rebuilt at some point since then.
