Most of fault lies with the road/land owner for not properly blocking of that bridge and for not maintaining it. Nearby residents have also tried to get them to block/repair the bridge properly, but they haven't.

And they are luckily also getting sued in the lawsuit.

Googles should take some blame for not updating their maps for 9 years despite multiple notices from users that the bridge has collapsed.

Btw if you look at street view and satellite images, it clearly isn't a dirt road.
