You can't take a bridge to the other side because of invisible barriers. I have found a way to get past them. However, you are very limited to what you can do. First, go to the Manhattan Bridge because it is a long one. Go within barriers and be on the side of the bridge where cars are heading to the barrier and beyond (right side). Jump on one of the cars and immediately enter Photo Mode. Hopefully, the car will continue driving and will drive past the barrier. You are still alive and are able to move around, zoom in, and take photos. You cannot leave Photo Mode because you will be catapulted back to the barrier. You can go as far as the other borough that is heavily lighted in the night time. At a certain point (usually when the bridge ends), you will reach a gray screen, and the only thing you can do is push the Start button and start over.
