Hi,
could you check these edits?
The man_made=tunnel in the North is a lot longer than the tunnel marked on the road. 

You also used 'maxheight' tags on the tunnel - they belong on the road. 'maxheight' always describes a legal height limit, not the actual height of an object.

'maxheight:physical' describes the actual limitations, but only on roads.

On the tunnel itself I recommend using 'height' for the actual height in the middle and height:left / height:right for the height at the sides.
