Hi hhrazaka,
unfortunatly your changes did not solve the issue but added more problems like overlapping highways. Instead of extending the bridge the missing highway should have been added as member to the relation.
I have reverted your CS with https://www.openstreetmap.org/changeset/158743474 and will further comment on https://community.openstreetmap.org/t/121071.

Cheers,
