You really made me uncertain there for a moment so I popped the DVD back in and checked again. The other side of the road, as far as I can tell from the available shots, is perfectly clear.
Apologies for the bad image quality. I think the burning fire truck is clearly visible. But I think you can also see that there is nothing blocking the other side of the road (left of the down ramp), neither on the height of the fire truck nor further behind:
I just watched the film on Blu-ray and if you look a little ahead, there are vehicles on the road up ahead. The picture just
cuts it off where the intersection lies. Trust me.
To be entirely fair, even if I were to accept your assertions, I shouldn't need to watch a Blu-ray Disc version of a movie to get the whole thing.
I love The Dark Knight
, but the move down to Gotham's equivalent of Lower Wacker Drive is not
an excuse for poor scripting and editing.
