When the National Highways Authority of India (NHAI) formally awarded work on the long-delayed Zirakpur-Panchkula bypass and its connecting Spur in March, it looked like the last barrier had finally fallen. But there was one more hurdle quietly waiting in the wings — a small but strategically placed strip of Army land at the Chandimandir Military Station that the Bypass simply could not go around.The Ministry of Defence has now cleared that hurdle too, granting NHAI working permission for 2.7461 acres of defence land — unlocking the last administrative obstacle standing between blueprints and bulldozers on one of the most consequential highway projects in north India.Here is everything you need to know.What exactly happenedThe Ministry of Defence issued a formal working permission to NHAI, allowing it to use 2.7461 acres of defence land at Chandimandir Military Station — valued at ₹9,88,85,963 (approximately ₹9.89 crore) — for the construction of the 6-lane Zirakpur-Panchkula Bypass.The permission, issued with the financial concurrence of MoD (Finance), and signed by Vikram Verma, Deputy Director (Lands), Ministry of Defence, clears the way for NHAI and its awarded contractor, RKCPL Limited, to formally take possession of this parcel of Army land and begin physical construction work on the ground.A copy of the order is with The Tribune.Why was this piece of land so importantThe 19.2-km Zirakpur-Panchkula Bypass runs from its junction with NH-7 at Zirakpur-Patiala to NH-5 at Zirakpur-Parwanoo — cutting through one of the most built-up and militarily sensitive belts in the Tricity region. The Chandimandir Military Station, a major Army cantonment on the outskirts of Panchkula, sits directly in the alignment of the Bypass corridor.In highway construction, there are no detours around immovable obstacles. When a national highway passes through defence land, it cannot simply be rerouted to avoid the inconvenience — the alignment is fixed by engineering, topography and traffic logic. NHAI had no choice but to seek and secure MoD’s explicit permission before a single machine could move on that stretch.Without this clearance, construction on the Bypass could not legally commence — regardless of how many contractors had been hired or how much money had been committed.Why did it take so longDefence land acquisition in India is one of the most complex and time-consuming administrative processes in public infrastructure. It involves multiple layers of bureaucratic clearance — the local military authority, the Defence Estates Officer, the MoD’s Lands division, MoD (Finance), and ultimately the Union Cabinet for permanent transfers.The Zirakpur-Panchkula Bypass project was first conceived in 2020, when land acquisition was completed. The project’s forest clearance — another critical prerequisite — came much later. Simultaneously, NHAI had to navigate the separate but equally complex process of securing MoD’s agreement on the defence land parcel.The fact that MoD’s Finance wing gave its concurrence only on March 11, 2026 — and that the formal working permission followed thereafter — illustrates just how long the bureaucratic pipeline runs for defence land, even after the physical infrastructure project has been fully designed, approved, bid out and awarded.Who pays what — and howThis is where the arrangement gets interesting. The defence land has been valued at approximately ₹9.89 crore. But NHAI will not write a cheque for that amount.Instead, the compensation has been structured on an Equivalent Value in Infrastructure (EVI) basis — a mechanism used by the Ministry of Defence for cases where cash payment is replaced by construction of infrastructure of equivalent value for the benefit of the armed forces.Under this arrangement, NHAI will construct approximately 32 married accommodation units for Junior Commissioned Officers (JCOs) and Other Ranks (OR) at Chandimandir Military Station itself. The total estimated cost of this accommodation is approximately ₹12 crore. Since the defence land is valued at ₹9.89 crore, the remaining ₹2.21 crore will be funded from the Defence Budget of the Army.In effect, the Army gets new housing for its soldiers. NHAI gets the land it needs for the Bypass. And no cash changes hands between the two. It is a barter of infrastructure for infrastructure — a model the MoD increasingly prefers because it ensures the armed forces derive a tangible, lasting benefit from the land they give up for national projects.The exact number of dwelling units, however, may change marginally at the time of the Memorandum of Understanding (MoU) between NHAI and the Army, depending on final project costs and any applicable cost escalations.What are the conditions NHAI must meetThe working permission comes with a detailed set of binding conditions, all of which NHAI — and its contractor, RKCPL Limited — must comply with to the letter.A Board of Officers (BOO), comprising representatives of NHAI, the Defence Estates Officer and the Local Military Authority, must be constituted and must complete the physical demarcation of the land — ascertaining exact area, survey numbers, location of existing assets, and security considerations — within four weeks of the working permission’s issue.The physical handing over of the land from the Army to NHAI must happen within one month of the working permission. If NHAI is unable to complete this within the stipulated time for reasons attributable to itself, and if land costs rise in the interim, a fresh financial sanction will need to be obtained.During construction, NHAI must ensure that no defence asset is damaged — boundary walls, sewerage lines, water supply pipelines, communications networks and electrical lines must all be protected. If any utility is disturbed by construction activity, NHAI must restore it fully and at its own cost, before dismantling any existing infrastructure.Security of the military cantonment cannot be compromised at any stage. All safety and security measures as directed by the Station Commander must be followed throughout the period of construction. Photography on site requires prior permission from the Local Military Authority.NHAI must also comply with air and noise pollution norms prescribed by the Pollution Control Board throughout the construction period, and must provide written commitment to take mitigation measures against vibrations from construction work — a significant consideration given the proximity of serving personnel and their families.The defence land cannot be mortgaged or sold to any third party and must be used exclusively for the purpose for which the working permission has been granted.Is the transfer permanentNot yet. What has been issued is a working permission — it allows NHAI to use the land for construction purposes. The formal, permanent transfer of the 2.7461 acres of defence land to NHAI will require a separate Cabinet approval, which the MoD has committed to pursue. The working permission is a bridge that allows construction to proceed while the longer process of Cabinet sanction for permanent transfer runs its course through the government machinery.The General Land Register and Military Land Register will be updated by the DEO accordingly once the formal sanction is in place.What happens next — and by whenThe sequence now is as follows. The Board of Officers must demarcate the land within four weeks. NHAI must take physical possession within one month. RKCPL Limited, which won the Bypass contract at ₹1,380 crore and is 14.06 per cent below NHAI’s own estimate of ₹1,605.85 crore, must confirm acceptance of its Letter of Award within seven days of receipt, and execute the full Concession Agreement with NHAI within 45 days. It must also deposit a Performance Security Bank Guarantee of ₹69 crore — 5 per cent of its bid cost — within 30 days of signing the Concession Agreement, and must incorporate a Special Purpose Vehicle (SPV) as a limited liability company before construction commences.On the Spur, Ceigall Infra Projects Pvt. Ltd. — which won the ₹603-crore contract at 14.19 per cent below NHAI’s estimate — faces identical timelines for its own concession agreement, SPV formation and performance security of ₹30.15 crore.Once both SPVs are operational and the Concession Agreements are executed, physical mobilisation on both stretches is expected to begin. The Spur carries an 18-month completion deadline from the award date, pointing to late 2027. The Bypass carries a two-year completion deadline, making early 2028 the target for Zirakpur’s long-suffering commuters.What does all this mean for Zirakpur, TricityEverything. Zirakpur is currently the single most congested junction in the Tricity — a town that was never designed to handle the volume of freight trucks, inter-state buses, hill-bound tourists and daily commuters that now converge on it from every direction. Traffic from Delhi, Ambala, Patiala, Chandigarh, Panchkula and Shimla all funnel through its narrow grid, with no alternative route available. The result is gridlock that adds hours to journeys and costs millions in fuel, time and economic productivity every single day.The Bypass solves this at its root. Its 6.195-km elevated section, multiple flyovers and railway overbridge will allow through-traffic — particularly heavy freight and long-distance vehicles — to leapfrog Zirakpur entirely and connect directly to Panchkula and onward toward Himachal Pradesh. The Spur completes the geometry by catching vehicles arriving from Ambala and Delhi on the greenfield Ambala-Chandigarh Expressway near Rajo Majra village and channelling them directly onto the Bypass — before they have any opportunity to enter Zirakpur’s streets at all.Together, the two projects form the vital southeastern arc of the ₹12,000-crore, 244-km Tricity Ring Road — an eight-project orbital network that, once complete, will redirect thousands of vehicles daily away from the internal arteries of Chandigarh, Mohali and Panchkula, improving air quality, cutting travel times and strengthening connectivity across Punjab, Haryana, Himachal Pradesh and Delhi-NCR.The MoD’s clearance of 2.7461 acres is, in that sense, far larger than its acreage suggests. It is the piece that makes the whole puzzle possible.Key numbers at a glanceDefence land cleared: 2.7461 acres, Chandimandir Military StationLand value: ₹9.89 crore (EVI basis)Army gets in return: 32 JCO/OR married quarters (₹12 crore)Bypass contract: RKCPL Limited, ₹1,380 crore (2-year deadline)Spur contract: Ceigall Infra Projects, ₹603 crore (18-month deadline)Combined construction value: ₹1,983 croreZirakpur relief expected: Late 2027 (Spur) and early 2028 (Bypass)Part of: ₹12,000-crore, 244-km Tricity Ring Road(Source: Ministry of Defence)
