There is a workaround for that bug. Enter the screen with the bridge that you hammered away on your first trip in, then head back 1 screen and F6 -> Continue. The bridge should be back so you can cross it.
For the final battle, you'll have to start out by using the lens of truth to reveal a trigger, then prepare for a fight.
Colossal is right. That workaround actually is a bug itself I left in there just in case people ran into troubles like this.
I don't understand the nature of the issue though, I though I fixed the bug in Ganon's castle. In Ganon's castle the are four entrances from the outside.
1: Main entrance.
2: 2nd Floor Entrance (Right)
3: 2nd Floor Entrance (Left after beating Ganon round 1)
4: Ganon's Tower Entrance.
When you first reach Ganon's castle you can only enter the main entrance. On both sides of the main entrance are ladders that have to be dropped from above b'y attacking statues. Depending on which path you take in Ganon's Castle will lead to either entrance 2 or entrance 3.
If you taken the route that leads to the gold ring, you will also reach the 2nd entrance (on the right side) which will give you freedom to leave or enter the castle at any time providing you hit the statue and drop the ladder.
However, the tower is blocked off so you must find the 3rd entrance in which you must take an alternate route in the castle. You will eventually encounter your first battle with Ganon and receive a key which unlocks all the doors on the 2nd floor, including the 3rd entrance on the left side that leads to the tower and also another ladder you can drop.
At this point you can enter and leave the castle and the tower at any time.
That's how it should work. But Mystery, you say there is a bug that makes you unable to enter the castle because Ganon did not drop a key. But if he did not drop the key, you would not have been able to unlock the door to the third entrance that leads to the tower. Mystery, can you explain further so I can understand? Thanks!

Ps: I would also like to note, if there is a bug that prevents you from opening a door on the 2nd floor, you can still go downstairs into the main floor of Ganon's castle and still take the alternate route. However, if things are working correctly, you should be able to have full access to the second floor after beating Ganon (round 1).
