Hello Nazmul Patwary Nayeem, I noticed there were many modifications made to the road network in Cumilla Adarsha Sadar Upazila that I wanted to ask you about.

The oneway tag was applied to major roads, such as Comilla–Brahmanbaria Highway (https://www.openstreetmap.org/changeset/161806447, https://www.openstreetmap.org/changeset/162582176), while imagery shows vehicles traveling in the both directions. I also noticed not only some bridge and tunnels were missing layer tags, but I cannot verify that the bridge is operational from aerial imagery (https://www.openstreetmap.org/way/1354369790, https://www.openstreetmap.org/way/1357699854). If the bridge is under construction, then it would be appropriate to change the highway tag to construction (https://wiki.openstreetmap.org/wiki/Tag:highway%3Dconstruction#How_to_map).

There are areas where link classification is applied to highways that do not match the OSM definition of a link (https://www.openstreetmap.org/way/1355909431).

Looking at the highway network holistically the network seems to be overly classified. Such as this secondary that is used to access a rural area  (https://www.openstreetmap.org/way/1354154921), tertiary feature accessing what appears to be a residential area (https://www.openstreetmap.org/way/547589398), and primary roads that would be better classified as secondary (https://www.openstreetmap.org/way/548822066).

I am curious about the sources you are using to support these modifications. Do you have any thoughts on reclassifying roads in cases where the current classification does not best fit the OSM definition?
