Hmm... I would drive across a bridge meaning its length. I would walk across the road if I wanted to get to the other side. I would walk along a road if I were heading in the same direction it is.We drive across a bridge and we walk across a road.
Yes, you can.If I started on the south half of a bridge and finished on the other side, can I say "I walked across the bridge".
You can use "I walked across the bridge" whichever side you start from.Is it different from starting on the south side to the north side?
