Hi, There are lots of duplicated sections of highways across the airport. Please see here:- https://tools.geofabrik.de/osmi/?view=routing&lon=72.62122&lat=23.07271&zoom=17&baselayer=Geofabrik%20Standard&overlays=duplicated_edges%2Cduplicated_edges%2Cduplicated_edges_areas

Could you please remove the duplications?

Regards Bernard.
