I feel like this could have a particular name, but I would just call it lane or corridor, I am not sure if there's a better word for it though.

I think the word you are seeking is a "drive"
I fix really old barns for a living and they actually were pretty utilitarian and practical when they were built. Everything was designed on a gravity system and the main drives had floor planks used for threshing grain. This was obviously before the advent of petroleum powered threshers but as usual just look into the past a little bit and its all there. Most of the information on this site has already been talked about 100 plus years ago.
Dictionary definition is: A drive is a wide piece of hard ground although it tends, nowadays, to be predominantly related to a type of roadway linking a house.
