The other side of the bridge

No, of course there is no gate.You just enter and that's all, you simply exist.
After some time you begin to look around and you realize that you are not alone.
You continue to search and you observe the bridge, the huge one, just in front of yourself.
It takes 50-60 years to go through but sometimes it can take less.
What's happening on the other side of the bridge? What will happen with you and your feelings once you'll be there?
