There is a stretch of road in Ladakh that sits at over 17,000 feet above sea level. The air is thin, the temperature plunges to minus 40 in winter, and yet a tarmac road runs through it — maintained year-round by an organisation most Indians have never properly heard of. That organisation is the Border Roads Organisation (BRO), also known as the General Reserve Engineer Force (GREF).
BRO builds and maintains roads in the most hostile terrain on earth — the Himalayas, Ladakh, the Northeast, Andaman and Nicobar Islands, and neighbouring countries like Bhutan, Myanmar, and Afghanistan. Its work is the reason India's army can move troops to the border in hours instead of days.
And then there are the signs.
Anyone who has driven on a high-altitude Indian road has probably stopped, laughed, and photographed a BRO signboard. Witty, philosophical, sometimes grammatically creative, these signs are as much a part of the BRO identity as the roads themselves.
This guide covers what BRO/GREF is, how it is governed, what its rank structure looks like, and a curated collection of its most beloved road signs — with a personal note from someone who grew up on one of its most critical project sites.
What is BRO (Border Roads Organisation)? — The Border Roads Organisation (BRO) is a road construction and maintenance organisation under the Ministry of Defence, Government of India. Established on 7 May 1960, it builds and maintains strategic roads, bridges, tunnels, and airstrips in border and remote areas of India and friendly foreign countries. Its military engineering workforce is called the General Reserve Engineer Force (GREF).
History: From Nehru's Vision to 18,000-Foot Roads
BRO was established on 7 May 1960 by the Government of India under Prime Minister Jawaharlal Nehru, who recognised that India's border areas — particularly the Himalayan frontier — lacked the road infrastructure needed for both development and defence.
The impetus intensified after the 1962 Sino-Indian War, which exposed how India's lack of roads in the Northeast and Ladakh had left its military unable to respond effectively. BRO was expanded rapidly after 1962 and has since been at the heart of India's strategic border connectivity.
Key milestones:
- 1960: BRO established; first Project Beacon (Ladakh) and Project Tusker (Northeast) launched
- 1962: Sino-Indian War accelerates BRO expansion across all Himalayan frontiers
- 1988: Rohtang Tunnel (now Atal Tunnel) project initiated; completed in 2020
- 2020: Atal Tunnel (Rohtang) inaugurated — world's longest highway tunnel above 10,000 feet at 9.02 km
- 2023: BRO sets world record by constructing roads at 19,400 feet — among the highest motorable roads on earth
BRO vs GREF: What's the Difference?
This is a common point of confusion:
- BRO (Border Roads Organisation) is the umbrella organisation — the institution as a whole, including its civilian and military components
- GREF (General Reserve Engineer Force) is the military engineering workforce within BRO — the uniformed personnel who actually build and maintain the roads. GREF personnel are military workers with ranks, uniforms, and service conditions similar to the Indian Army
When people say "GREF," they typically mean the uniformed workforce of BRO. When they say "BRO," they usually mean the organisation as a whole.
Who Governs BRO?
- Ministry: Ministry of Defence, Government of India
- Command: Director General Border Roads (DGBR) — an Indian Army officer of Lieutenant General rank
- Operational structure: BRO's field work is organised into Projects (e.g., Project Beacon, Project Himank, Project Deepak), each commanded by a Chief Engineer equivalent to a Brigadier-rank Army officer
- GREF personnel serve under these projects in ranks that parallel the Indian Army's JCO and OR structure
- Officer cadre: BRO's gazetted officers come from the Corps of Engineers of the Indian Army — Army officers posted on deputation to BRO projects
BRO's Major Projects Across India
| Project Name | Region | Key Roads / Areas |

111 RCC: A Critical Location — and a Personal Note
Among BRO's many Road Construction Companies (RCCs), 111 RCC holds a special place. RCCs are the field units of BRO — the companies that are directly on the ground, building and maintaining specific stretches of strategic road. An RCC is commanded by an Officer Commanding (OC), typically a Major from the Corps of Engineers on deputation to BRO.
111 RCC operates in a sector that is considered strategically critical — the kind of location where road connectivity isn't just about convenience but about the ability to move troops, equipment, and supplies to the border in time. The roads these units maintain are, quite literally, India's lifelines at the frontier.
This author's father served as the Officer Commanding of 111 RCC, and much of his childhood was spent living on the project site — in a world of tents, mountains, GREF workers, and road machinery at altitudes where most people get headaches just stepping off a flight. Growing up in a BRO environment gives you a perspective on this organisation that no amount of reading can replicate: the dedication of the men who work in minus-30 temperatures to keep a road open so that a truck can pass, or so that a soldier can reach his post.
BRO is not just an engineering organisation. It is a way of life for tens of thousands of families — officers, GREF personnel, and their children — who live at the frontier and call it home.
BRO / GREF Rank Structure
BRO's personnel fall into two categories:
- Indian Army Officers on Deputation: Corps of Engineers officers who command projects, divisions, and RCCs. They carry their Army ranks (Lieutenant General, Major General, Brigadier, Colonel, Lieutenant Colonel, Major, Captain).
- GREF Enrolled Personnel: The uniformed workforce with a rank structure parallel to the Indian Army's JCO and OR hierarchy.
BRO Officer Ranks (Indian Army Deputation)
| Designation in BRO | Army Rank | Role |
|---|---|---|
| Director General Border Roads (DGBR) | Lieutenant General | Apex command of all BRO |
| Additional DGBR | Major General | HQ and senior command |
| Chief Engineer (CE) | Brigadier | Commands a BRO Project |
| Superintending Engineer (SE) | Colonel | Commands a Division under a Project |
| Executive Engineer (EE) | Lieutenant Colonel | Commands a Sub-Division |
| Officer Commanding (OC) / Assistant Executive Engineer | Major / Captain | Commands an RCC (Road Construction Company) |
GREF Enrolled Personnel Ranks
| Rank | Pay Level (7th CPC) | Basic Pay (Rs.) | Category |
|---|---|---|---|
| Subedar Major (GREF) | Level 8 | 47,600 | Junior Commissioned Officer |
| Subedar (GREF) | Level 7 | 44,900 | Junior Commissioned Officer |
| Naib Subedar (GREF) | Level 6 | 35,400 | Junior Commissioned Officer |
| Havaldar (GREF) | Level 5 | 29,200 | Non-Commissioned Officer |
| Naik (GREF) | Level 4 | 25,500 | Non-Commissioned Officer |
| Lance Naik (GREF) | Level 3 | 21,700 | Senior Worker |
| Pioneer (GREF) | Level 3 | 21,700 | Basic enrolled worker / soldier |
Note: GREF's basic rank is Pioneer (not Sepoy or Constable), reflecting the engineering/construction nature of the force. Source: Ministry of Defence; bro.gov.in
The Famous BRO Road Signs: Wit at 17,000 Feet
BRO's road signs are a cultural institution. For decades, BRO has placed hand-painted and printed signboards along its high-altitude roads — safety messages written with a combination of genuine concern, dry humour, and occasionally inspired poetry. They have been photographed millions of times and shared across social media globally.
Here is a curated collection of the most celebrated BRO signs, grouped by theme:
On Speed and Safety
- "If you are married, divorce speed."
- "Speed thrills but kills."
- "Be gentle on my curves."
- "Darling I want you but not so fast."
- "After whisky, driving risky."
- "Don't gossip — let him drive."
On the Road Conditions
- "Go slow, maintain distance — we are not making you late, we are saving your life."
- "This is not rally. Please drive carefully."
- "Road is hilly, don't be silly."
- "Mountains are a pleasure only if you drive with leisure."
Philosophical and Poetic
- "Life is short, don't make it shorter."
- "Better late than never."
- "Peep peep — don't sleep."
- "Drive on horsepower, not rum power."
- "Safety is cheap, accidents are expensive."
On Altitude and Weather
- "You are not stuck in traffic. You are traffic." (on congested mountain passes)
- "Curves are beautiful — drive carefully."
- "Snow ahead — patience required."
- "Slow drive, long life."
The All-Time Classic
"After whisky, driving risky."
"On the mountains, don't be a dare devil."
"If you sleep, your family will weep."
These signs appear on roads like the Manali-Leh Highway, Zojila Pass, Rohtang Pass, Nathu La, and the Trans-Arunachal Highway. BRO has in recent years also modernised many signs into reflective boards, but the wit remains.

Frequently Asked Questions
What is BRO in India?
BRO (Border Roads Organisation) is a road construction and maintenance organisation under India's Ministry of Defence, established on 7 May 1960. It builds and maintains strategic roads, bridges, tunnels, and airstrips in India's border and remote areas, as well as in friendly foreign countries. Its uniformed engineering workforce is called the GREF (General Reserve Engineer Force).
What is GREF?
GREF (General Reserve Engineer Force) is the uniformed military engineering workforce of the Border Roads Organisation. GREF personnel are enlisted workers and junior commissioned officers who carry out the actual road construction and maintenance work in BRO's project areas. Their basic rank is Pioneer (not Constable or Sepoy), reflecting BRO's engineering identity. GREF personnel serve in conditions as harsh as any combat soldier — at altitudes above 18,000 feet in extreme cold.
Which ministry controls BRO?
BRO is under the Ministry of Defence, Government of India — unlike most road agencies which report to the Ministry of Road Transport & Highways. This is because BRO's primary mandate is strategic military connectivity, not civilian infrastructure. Its Director General is a serving Indian Army Lieutenant General.
What is the highest road built by BRO?
BRO built the road to Umlingla Pass in Ladakh at an altitude of approximately 19,300 feet (5,883 metres) — recognised by the Guinness World Records as the world's highest motorable pass road. This road, in the Demchok sector of Ladakh, was opened in 2021 and provides critical military access to India's forward areas near the Line of Actual Control.
What does OC mean in BRO?
OC (Officer Commanding) in BRO refers to the commanding officer of a Road Construction Company (RCC) — the basic field unit of BRO. An OC is typically a Major from the Indian Army's Corps of Engineers, posted on deputation to BRO. The OC is responsible for the construction, maintenance, and all operations of the RCC in its assigned sector of road.
Why are BRO road signs so funny?
BRO's witty road signs emerged as a practical safety communication strategy for roads where drivers — often unfamiliar with high-altitude driving — needed memorable reminders to slow down and drive carefully. Over decades, BRO sign writers developed a distinctive voice: part safety manual, part philosophy, part humour. Signs like "If you are married, divorce speed" and "After whisky, driving risky" became cultural landmarks as tourism to Ladakh and Spiti grew. They are now as much a part of the BRO identity as the roads themselves.
What is the Atal Tunnel built by BRO?
The Atal Tunnel (Rohtang) is a 9.02 km highway tunnel at an altitude of approximately 10,000 feet, located on the Manali-Leh Highway in Himachal Pradesh. Built by BRO, it is the world's longest highway tunnel above 10,000 feet. Inaugurated in September 2020, it provides all-weather road connectivity to the Lahaul-Spiti Valley and Ladakh, which were previously cut off for up to six months each year due to snow on the Rohtang Pass.
