This is an important development.https://www.tribuneindia.com/news/nation/india-completes-vital-ladakh-road/762332.html
From the article:
The 255-km Darbuk-Shayok-Daulat Beg Oldie (DS-DBO) section of the road between Leh and Karakoram Pass has been completed, sources said. Some 37 bridges have been built across various snow-fed rivers.
Shyok Village: 34.1772188,78.1345939
Murgo: 35.0412144,77.9359818 (not mentioned in the article but an important point on the route)
Burtse Camp: 35.1306079,78.0250103 (not mentioned in the article but an important point on the route)
This road will allow Indian Army to move troops to DBO Sector (also called as Sub Sector North-SSN) from two axis.
One axis is what is referred to in the article. This requires troops to move from Leh over Chang La pass and then downwards to reach Darbuk. If you take south from here, one goes towards the Pangong Tso lake. If you move northward, you come to Shyok Village and thence north & north-east wards DBO.
Second axis the route from THOISE - you go due east along the alignment of Shyok River to reach Shyok Village and then follow the route towards DBO.
Indian Army had inducted a brigade especially for DBO/SSN as part of overall beefing up of troops for eastern Ladakh. DBO/SSN sector had also seen multiple large scale Chinese incursions. In fact, Google Earth will show you armor in Darbuk. If required, the same can now go north towards DBO/SSN through this route.
