Well the problem is there seems to be a height limit.

This game has allot limits. For one there is a limit to how far you can dig down but also it has a limit how much you can raise terrain.

In addition there is a static system in the game, you can only built that tall. I see you use those Core Wood pieces, the next stronger material would be Ironclad Poles.

One thing you could do... is build the bridge lower in the ravine. You could dig out some of the ground on both sides, so that the bridge sits overall lower in there.

That being said, this game doesn't want you to build bridges. It is very hard to place building pieces underwater, especially since there is no diving mechanic, you can use console commands and force your character to fly underwater... but the camera gets stuck above water(which doesn't help).
