[Tagging] Tunnels and bridges

Not splitting the way for every bridge will make tagging a lot easier. Often when things such as speed limits on long sections of road, bridges get missed and then often the cause of extra routing instructions if a reference tag is missing.

Why do you need split the road at the edges of the bridges? This is 
currently done because it is the only way of defining the bridge. If we 
are to split the two features, then this need disappears. If the bridge 
crossing ways have width or weight limits, these do not necessarily 
coincide with the structural limits of the bridges. They often apply to 
the approaches as well, so the section of the road where the restriction 
applies begins and ends beyond the bridge.
