Hi, I agree with you Martin. And that's why I'm looking for a way to say "those power lines/lanes/roads are on the same bridge/tunnel".
As you mentionned, the tunnel/bridge name can precise which bridge is but it's not a relational (or even spatial) way of bringing objets together. Ok a tunnel isn't easy to map since we can't use GPS. But nothing prevent us to create a relation to setup such a link between roads and bridge for example. That's why I'm interested by the proposal given above. Nobody wants it accepted ? Cheers.
