A deadly standoff jolted India to stitch together a huge network of roads, tunnels, and landing strips needed to move soldiers and supplies to the border region.

India’s bloody border clash with China in 2020, which killed soldiers on both sides, exposed an alarming vulnerability along the disputed 2,200-mile border, a vague demarcation line known as the Line of Actual Control (LAC). While China has for decades built up a vast network of railways and roads along its border regions, India has done little to build the infrastructure its military would need to traverse its own mountainous border areas.

When fighting erupted in 2020—soldiers at 14,000 feet fought hand-to-hand using batons and clubs wrapped in barbed wire—Beijing could have rushed in reinforcements within hours, according to analysts. India would have needed up to a week to send additional troops along its bumpy or nonexistent roads. Now, New Delhi is racing to close that gap, with top officials confirming that.

Why It Matters

For decades, India avoided large-scale construction along much of its border, calculating that the soaring Himalayas and a lack of roads would deter a Chinese incursion. “It was like rolling out the red carpet to a Chinese invasion,” said Daniel Markey, a senior fellow at the Stimson Center. “The Indian perspective was that building significant roads was actually militarily detrimental to them.”

That thinking has shifted dramatically. The logistics of maintaining a military presence in the high Himalayas are grueling. Supplies first travel by truck or train to depots in Jammu and Kashmir, then move by truck convoys to Leh, the capital of Ladakh. From there, smaller vehicles navigate rough terrain before porters and mules haul baskets on the final stretch, up to 20,000 feet above sea level.

“It’s a massive, massive logistical exercise undertaken regularly every year,” said Lt. Gen. Deependra Singh Hooda, former commander of India’s Northern Command. Each soldier needs about 220 pounds of supplies monthly. An outpost for 30 soldiers burns through about 13 gallons of fuel a day. Currently, heavy snowfall cuts off Ladakh for up to six months a year, isolating military outposts and civilian settlements.

What to Know

The government has launched a massive drive to upgrade connectivity. Defence Minister Rajnath Singh inaugurates 125 border infrastructure projects recently, signaling a robust commitment to securing the LAC.

• The Zojila Tunnel: One of the most ambitious projects is the Zojila tunnel, being carved into the mountains at around 11,500 feet. The more than $750 million project began shortly after the 2020 clash. Once completed, the 9-mile stretch will reduce travel time between Kashmir and Ladakh from 3 hours to 20 minutes, ensuring year-round movement of troops and supplies.
• Mudh-Nyoma Airbase: At nearly 14,000 feet, the new Mudh-Nyoma air force base in Ladakh is India’s closest airfield to the border, with China just 19 miles away. The base is capable of handling heavier military transport planes, such as the U.S.-made C-130J, serving as a vital staging ground for troops and equipment.
• Pangong Tso Lake: This 80-mile alpine lake remains a friction point. Since 2020, China has constructed radar sites, trenches, and a bridge linking the north and south banks. In response, India has rapidly upgraded its outposts and road systems along the shore.
• Rising Budget: The budget of the Border Roads Organization (BRO) has grown to $810 million this year, up from $280 million in 2020. India’s total military spending has jumped nearly 60% to $80 billion during the same period.

What People Are Saying

Military leadership in India is confident that the infrastructure gap is closing. Lt. Gen. Raghu Srinivasan, the Director General of the BRO, emphasized the pace of development, noting that India fortifies border infrastructure with 125 strategic LAC projects</a> to ensure operational readiness.

“It was a dramatic shift in thinking,” said Maj. Gen. Amrit Pal Singh, former chief of operational logistics in Ladakh. “We realized we needed to change our total approach.”

Regarding the new surveillance reality at Pangong Tso, Rajeswari Pillai Rajagopalan of the Australian Strategic Policy Institute noted that in contrast to occasional patrols before 2020, Indian forces now “believe that you have to have constant, regular, 24/7 monitoring of Chinese movement.”

What Happens Next

Construction crews face immense challenges, including landslides, avalanches, and temperatures dropping to minus 40 degrees Fahrenheit. Work often halts for months during the winter when tasks like mixing cement become impossible. Consequently, the Zojila tunnel’s completion date was recently pushed back to at least 2028.

Despite the hurdles, the strategic push continues. Tensions remain high; in 2017, troops faced off over a road China was building near Bhutan, threatening the Siliguri Corridor—the narrow “Chicken’s Neck” connecting India to its northeastern states. With the BRO chief asserting that the country will be fully “infra-ready” within five years, the race to fortify the Himalayas against future clashes is set to accelerate.
