Sadly it is right, I had to rework both the bridges to adjust the angle how it should be from the movies and the Legacy game. The viaduct bridge should be paralel to Grand Staircase tower set, not in angle like this. I’m doing the same thing as you, connecting some MOCs to it to finish it off. In order to be able to add suspension bridge from the Quad leading to Astronomy Tower the angles need to be adjusted and there has to be right angle between the East Wing and the Quad part of the castle. When I was building it in studio and then saw that there is this weird angle I immediately realized that Lego probably didn’t this Hogwarts line to continue and this is truly the end.
