Hi FE Edu VN
A lot of mapping done, great work.
Currently I'm doing line crossing waterbody check using MapRoullete  and I spotted that there's highway added as residential highway (Cầu Triệu Phong) crossing the river (https://pewu.github.io/osm-history/#/way/1153578581) which I can't found any highway in any imagery. Have you any information about this highway or any bridges since it is newly added. Many thanks, cheers!
