Hi, Prabin Pokhrel.
Thank you for your mapping contribution.

I found crossing highway/water body issues on the water body (river) that you mapped (https://pewu.github.io/osm-history/#/way/1001622408). 
I want to fix this issue but I'm not sure how to do it because I'm a remote mapper and only see the highway features and river from satellite imagery. So, I want to discuss it first with local mapper.

The river looks wider when viewed from the maxar imagery than from bing imagery.  Maybe do you know whether the river is intermittent or not? or maybe are there seasonal floods or heavy rainfall in that area so the water overflowing it banks?

If you have any suggestions to fix this issue, please let me know. Thank You. 
Happy Mapping!
