That is, can you prevent an enemy army from crossing if you place a navy on top (SS included) of the landbridge ?

I have had AI stop me from moving across. Also, I believe, I have been successful at blocking the AI the same way. I had a weak garrison + a fleet sitting on the straights while the AI had a huge army on the other side. The AI never crossed.
You definitely can. I just had this happen playing as the Mori. The Shoni declared war on me and sent a full stack across the landbridge between us. Unfortunately for them, I've been kicking their butts at sea and just happened to park a fleet in the gap, which prevented any further crossings and isolated their initial invasion. They've got another full stack trying to get across and reinforce, but it can't.
lucky for you the AI almost never does naval landings huh!?
