maybe this query may be a bit trivial or perhaps laborious, but for a project I need to obtain the bridges that exist in an osm file along with its location (latitude and longitude).

Reading the openstreetmap wiki, I see that there is a procedure using osmosis but I do not know if I will actually get the information as follows:

Name of the bridge | latitude | longitude

bin / osmosis.bat --rx brandenburg.osm.bz2 --bp file = "city.poly" --tf accept-ways highway=motorway_link,motorway --way-key-value keyValueList="bridge.yes" --used-node --write-xml brdg_autob.osm

Thanks in advance Pablo

The output will be OSM XML and not plaintext.

Also, most bridges in OSM are mapped as ways. A way consists of multiple lat/lons represented as nodes. If you need a single lat,lon pair then you have to calculate the bridge center yourself.

Additionally, not all bridges are tagged as bridge=yes. See bridge in the OSM wiki for a list of commonly used tags, such as bridge=viaduct, bridge=aqueduct, bridge=boardwalk and so on.

You won't exactly get the format you described. However with some little work you can transform OSM XML into your format.
