Gaya Industrial Smart City (IMC Gaya) — Connectivity: Airports, Highways, Rail & Freight Corridor

Airports

The project's own promotional material lists Gaya International Airport as one of its core connectivity anchors, alongside the railway station and two national highways.

IMC Gaya's project cost is INR 1,339 crore, and the site is situated 39 kilometers south of Gaya International Airport. Gaya Airport (IATA: GAY) is an international airport serving Gaya, Bihar, located 12 kilometres southwest of Gaya and five kilometres from Bodh Gaya. It currently functions as a seasonal, pilgrim-focused facility: it is mainly seasonal and primarily caters to Buddhist tourists coming from South-East Asian countries such as Thailand, Bhutan and Myanmar, and separately it also serves as the only place in Bihar from where Hajj pilgrims take a direct flight to Jeddah and Madina.

Expansion has been proposed for years but remains largely stalled. An additional 40 hectares of land is under process for acquisition for runway expansion, with AAI having requested a further roughly 80 hectares from the Bihar government to allow the airport to be expanded. Planned works include construction of a new passenger terminal building to replace the current structure, expansion of runway 10/28, and installation of a CAT-I ILS approach system. As of the most recent tracking available, the expansion has been a non-starter since 2012 due to pending land acquisition. There is no other operational commercial airport closer to the IMC site; Patna's Jay Prakash Narayan Airport, roughly 100+ km away, is the state's other major gateway but is not cited by NICDC as a primary connectivity point for this project.

Expressways and Highways

IMC Gaya's location was chosen specifically for its highway junction. The project is positioned near Gaya Railway Station, NH-22, NH-19, Gaya International Airport, Fatuha Multi-Modal Logistics Park and Patna ICD. The actual IMC land parcel is located near Dobhi in Bihar, spans 1,670 acres, and has received environmental clearance from the Ministry of Environment, Forests & Climate Change — Dobhi itself is the physical meeting point of the two highways: Dobhi village sits at the junction of NH-19 (Grand Trunk Road) and NH-22, the latter connecting to Bodh Gaya, Gaya and beyond.

• NH-19 (Grand Trunk Road): NH 19 connects Agra to Kolkata across Uttar Pradesh, Bihar, Jharkhand and West Bengal, passing through Dobhi (Gaya) in Bihar, and is almost entirely part of the Golden Quadrilateral network — an operational six-lane national highway.
• NH-22: This highway runs approximately 388 km from Sonbarsa on the Indo-Nepal border to a junction with NH-39 near Chandwa, Jharkhand, passing through Patna, Gaya, Bodh Gaya and Dobhi. Its Bihar-relevant upgrade is complete: the four-laning of the 127 km Patna–Gaya–Dobhi section was completed and inaugurated in May 2025 at a cost of ₹5,520 crore, funded partly by JICA. This is expected to cut travel time between Patna and Dobhi from 3.38 hours to 1.56 hours — a direct benefit to freight and worker commuting for the IMC.
• Under Bharatmala Phase I, about 100 km of NH-22 in Jharkhand has been selected for upgradation, targeted for completion by 2026 (as of 2023) — this is outside Bihar but part of the same freight route south toward Ranchi.
• New greenfield road links: Three greenfield road projects have been proposed to further improve IMC Gaya's accessibility, though detailed alignments and construction dates have not been published as of this writing.

Rail and Dedicated Freight Corridor

Gaya's rail position is a long-standing asset: the town sits on the historic Howrah-Gaya-Delhi line connecting Delhi and Kolkata, part of the Grand Chord main line, and NICDC counts proximity to Gaya Railway Station among the IMC's core advantages.

On freight rail specifically, the site is promoted as being on the Eastern Dedicated Freight Corridor (EDFC): the project is linked to the Eastern Dedicated Freight Corridor, which aims to bolster regional industrial capabilities, and IMC Gaya's strategic location along the EDFC strengthens its connectivity and transport efficiency. The status of that corridor needs separating into two parts:

• Ludhiana–Sonnagar (Bihar) section — operational. The Eastern DFC, which runs from Ludhiana to Sonnagar, is 100% complete and operational, and separately reported as 1,337 km from Ludhiana to Sonnagar, with construction wrapped up in early 2024 and full operation since April 2024. Sonnagar is in Bihar, roughly on the same rail corridor as Gaya.
• Sonnagar–Dankuni section (passes near Gaya/Jharkhand) — not built as a new dedicated line; being handled as track multiplication instead. The Sonnagar–Dankuni section, originally part of the EDFC, spans about 538 km across Bihar, Jharkhand and West Bengal; in 2022 the Sonnagar–Andal portion was sanctioned as a multi-tracking project under EPC mode and handed to East Central Railway and Eastern Railway rather than being built as a fully separate freight-only line. An earlier official account confirms the shift in approach: the government decided to abandon the proposed 538-km Sonnagar–Dankuni EDFC section, focusing instead on laying third and fourth tracks on the existing Sonnagar–Andal line. In practical terms, freight capacity near Gaya is being added to the existing mainline rather than via a wholly new DFC alignment.

For context on scale, the EDFC overall is designed for annual freight traffic reaching roughly 116 million tonnes upward and 28 million tonnes downward, primarily coal, steel, food grains, cement, fertilisers and general merchandise — commodities relevant to IMC Gaya's targeted sectors (food processing, light engineering, building materials).

Metro, RRTS and Ports

No metro rail or Regional Rapid Transit System (RRTS) project has been announced, is under construction, or has been formally proposed for Gaya city or the IMC site as of mid-2026 in any of the official NICDC, BIADA or Bihar government material reviewed. Gaya is landlocked and roughly 500 km from the nearest major seaport (Kolkata/Haldia); no port link is documented for this project. The closest analogues in the wider NICDP programme — such as Dighi Port Industrial Area in Maharashtra — are unrelated coastal projects and do not connect to IMC Gaya.

Internal Road Network and Multimodal Access

Within the boundary of the cleared 1,670-acre site, the project's approved infrastructure plan includes a dedicated internal grid rather than relying solely on external highways. The cluster's infrastructure includes a skill development centre, fire station, administrative office, parking and commercial space, plus a 29.89 km internal road network, 220/33 KV and 33/11 KV electrical substations, 162 MVA assured power supply, and a 19 MLD water supply system. NICDC also markets the site's multimodal reach beyond the highway junction: IMC Gaya is expected to become a more attractive hub for domestic and foreign businesses due to its strong connectivity, including the Golden Quadrilateral and multi-track railway lines. A joint technical review has already been conducted on road access as part of due diligence for utilities: a recent joint site inspection evaluated proposed water storage systems and pipeline configurations, following a prior review of road connectivity — indicating road-access planning is active but construction milestones for the internal network have not yet been publicly dated.
