Hi Vera_D

Moi encore. Whenever roads cross buildings, carefully assess what and why to include he question "Is this a tunnel=building_passage? Here the layer=1 tag on the punto pedaggio roof was missing so the layer=-1 (standard tag on roofs these days) putting the motorway link underground at -1 was incorrect. Duly corrected. https://www.openstreetmap.org/changeset/134175277
