Bike rack was moved

No exact idea what this building is. Could maybe also be a sports building.

it's not grass

some grassy plain discovered with a couple of trees

removed name as it is irrelevant and loads map unnecessary

some error removed (spiky shape)

trying to approach reality

as OSM mapnik does not render flagpost and lamps, I have to use the area shape to get a reference to umap

adjusted building sizes

Found an areal picture of roaswork. Adapted a littel bit. Still not finished.

Second possible tunnel layout, this time alignes with entry and exit points and going closer to the street. The 2 manholes still have to be measured and found on the surface.

some fuzzy moving around to match with road layout. still crosses through building

explored the tunnel, it has many curves. Laynout still not correct. Give it a try!

added adress. For some reason it stays type line, despite building=yes.
