We've been discussing on the community forum what the meaning is of tags like height 76, layer 75.5 + min_height=0. Layers is a tag made for identifying if one object is higher or lower than another object, for instance a bridge is at layer=1 over ground.

Could you please fix the self intersection and give an understanding of this layer=75.5?

Many thanks and have a good day.

Rob

PS The Musical bridge in Rome has the multiple selfintersections reported in OSM Inspector. Please check and correct.

thx
