Been looking into the rules a bit but can't find all the answers I want and it's possible this is more of a house rule with no definitive answer, but what I'm looking for is some official ruling if it exists.
Do grass continue under bridges? i.e. is the grass connected? I'm thinking of the bridges from for example River 2 that cross the river.
Also does the grass go around the well/pond from River expansions? Usually even if no other tiles connect the grass we do play as if the grass does connect on well/pond. source
Do grass continue around the monastery from Catapult (that has the yellow fair thing stretching from one end to another)?
Finally Bridges, Castles and Bazaars I'm assuming grass under the wooden bridges does connect? Source
There are a lot more pieces in the expansions that basically asks the same question about farmer grass. If there is no official ruling I'm still interested in what is most common out there.
