Why not ask your question on the new OpenStreetMap Community Forum?

Hello, for a degree thesis I would like to carry out a census of Italian bridges with the data present from OpenStreetMap, which seem to me quite complete.

I extracted the data with Overpass Turbo and then exported it to uMap.

There are only two problems: 1) Many bridges are counted double because they are part of a two-way street. Is it possible to eliminate one of the two in the count? 2) By extracting the data province by province, the figures do not add up compared to a count made at the national level, because there are many bridges between one province and another. How can I delete duplicates?

Thanks to those who will answer me and happy new year. a

This has been generated by the overpass-turbo wizard.
The original search was:
“"bridge" is not null”
// fetch area Italia” to search in
// gather results

  // query part for: “bridge=*”
