Out of these 43 bridges, 10 are in Jammu and Kashmir, two in Himachal Pradesh, eight each in Uttarakhand and Arunachal Pradesh and four each in Sikkim and Punjab.
RM will also lay the foundation stone for the Nechiphu tunnel on a key road to Tawang in Arunachal Pradesh.
Most of the 43 bridges, including seven in Ladakh, are in strategically important areas and they will help the armed forces in ensuring quick movement of troops and weapons. The inauguration of the bridges built by the BRO comes at a time when India is engaged in a bitter row with China in eastern Ladakh.
India is expediting work on several key projects including on a strategic road linking Darcha in Himachal Pradesh with Ladakh that will criss-cross a number of high-altitude snow-bound passes.
The nearly 290-km-long road will be crucial for the movement of troops and heavy weaponry into the frontier bases of the Ladakh region and will provide a crucial link to the Kargil region.
