A city proposed, planned, funded and built, one dated step at a time.

The shape of the story

Before the year bands, here is the skeleton. Four phases have carried Dholera from idea to industrial city:

Where a month is well documented, it is given. Where sources differ or the record is fuzzier, only the year is stated, with an "around" where even the year is approximate. Conservative dates win over impressive ones.

2005–2009: From corridor idea to state statute

4.1 — The early concept

Dholera's modern chapter begins not with Dholera itself but with a corridor. In the mid-2000s, India and Japan were developing the concept of a Delhi–Mumbai Industrial Corridor: a band of industrial nodes strung along a dedicated freight rail line. Within that concept, Dholera, sitting on the coastal plain between Ahmedabad and Bhavnagar, was identified as a candidate for a large greenfield industrial region rather than an extension of an existing city. The full corridor background (why the DMIC existed, what India and Japan each brought, why a greenfield node on the Bhal plain was attractive) is covered in Chapter 3 — DMIC strategic position.

That greenfield choice shaped everything that followed. A node carved from farmland and coastal villages had no existing municipal machinery and no built utilities. That meant creating all of those things from zero, on land that floods, with farmers whose families had worked it for generations. The region's later protests, planning debates and flood-management design all trace back to this founding choice.

4.2 — The SIR framework (Gujarat SIR Act, 2009)

A greenfield region needed a legal machine: a way to plan it, assemble land and build infrastructure across hundreds of square kilometres without a municipal corporation to do it. Gujarat's answer was the Special Investment Region Act, 2009, which created a framework for notified investment regions with their own development authorities, planning powers and land-management mechanisms. The Act is the legal foundation everything after it rests on; how that governance machinery works day-to-day is treated in the Governance & Planning section (Chapter 7 onward), not here.

4.3 — The notification era begins

After the Act, the state moved to notify Dholera itself: defining the region, its villages and its extent, and constituting a development authority to run it. References differ on the exact notification sequence (some point to 2009, others to 2011), and early records describe a notified area of roughly 880 square kilometres before the commonly cited planning envelope settled at around 920 square kilometres. We state the sequence, not a single confident day.

2010–2014: Master planning the region

4.4 — Master planning milestones (the Halcrow plan era)

Planning a 920 sq km region from scratch produced one of the defining documents of modern Dholera: the Development Plan. It's worth pausing on that scale. An initial concept plan was prepared by UK-based engineering group Halcrow, and was then critically evaluated and developed further through a tendering process by Design and Planning Counsel (DPC), Ahmedabad, using satellite imagery, site verification, base maps and matched cadastral maps. The plan allocated roughly 433 sq km as developable urban area against a protected coastal regulation zone, defined a phased build-out, and laid the road network and trunk-infrastructure design the region still follows.

2015–2019: Institutions, money and first contracts

4.5 — Institutional milestones (DSIRDA, DICDL)

With a law, a notified region and a sanctioned plan in place, the missing piece was an implementation vehicle that both governments would fund. That arrived in 2015–2016: approval of trunk infrastructure for a first, compact activation zone, followed by the incorporation of a joint special-purpose vehicle.

4.6 — Infrastructure milestones: tenders and takeover

The second half of the decade shifted Dholera from paper to procurement. The single most consequential infrastructure decision was the expressway: proposed in 2010 by the state road department, it was taken over in 2019 by the National Highways Authority of India (NHAI), which commissioned a detailed project report and put the corridor on a national funding footing.

2020–2023: The build years

4.8 — Major construction milestones begin

The 2020s opened with the expressway's land being fully secured and its construction packages awarded, the first heavy civil works visible across the region. On the city side, the Activation Area moved from ducting and roads on drawings to ducting and roads on site. Roads first, tenants later. That sequence is easy to mock from the outside and hard to argue with on paper.

2024–today: The industrial anchor era

4.7 — Industrial announcements

The project's largest single industrial milestone arrived in February 2024, when the Union government approved the Tata Electronics fab for Dholera under the India Semiconductor Mission, India's first commercial front-end semiconductor fabrication facility. The date is 29 February 2024 in Tata's own announcement record, and it is the hinge on which Dholera's story turned from "planned city" to "manufacturing destination". I find this the easiest milestone to overstate and the hardest to ignore.

4.9 — Connectivity milestones

Connectivity is where the most recent, most firmly dated milestones cluster. Three corridors closed their loops in 2025–2026: the expressway was finished and inaugurated, the airport's airfield was completed with the terminal close behind, and the rail corridor moved from approval into procurement.

4.10 — The transition toward industrialisation

Read chronologically, the record shows a deliberate sequence rather than a burst. The state first created law (2009), then territory (notification), then plan (2012), then money and institutions (2015–2016), then roads, ducts and power (2019–2023), and only then did large industry arrive (2024 onward). That order is why the region's early years look empty to a visitor and why the plot of industrial land matters more than the calendar: Dholera spent most of its first fifteen years building the conditions a factory needs.

Two consequences follow from this ordering. First, the historical milestones cluster unevenly. Nothing happens for years, then several approvals land in one month, as they did in March–May 2026. Second, the transition is not finished by any dated entry on this page: the industrial era is under way, and everything from here forward is current status rather than history. That distinction is maintained in Chapter 6 — Dholera Ground Reality.

4.11 — Timeline through the current date

Every entry on this page has been checked against the latest dated primary sources available at the time of verification, with 2026 carrying the densest cluster: the expressway inauguration (31 March), the SEZ notification (9 April), the rail approval (13 May), the Tata–ASML announcement (17 May) and the airport progress review (14 July). Where the source record and popular claim diverge, we have kept the more conservative date, most visibly on the SIR notification, the DSIRDA constitution and the airport's operational status.

What this timeline deliberately omits is as considered as what it includes. It does not judge whether each milestone was achieved on time against an earlier promise, because public project dates move and this is a chronology, not a scorecard. It does not repeat investor-facing announcements that arrive without dated government records. And it does not carry forward claims from older research packages that no dated primary source currently supports, including several rail and airport details that circulate widely online. The verification method behind those exclusions is explained in How we verify.

What the timeline proves, and what it does not

The timeline shows a project that has survived successive governments, a pandemic and a decade of scepticism, and that has reached its dated milestones: a law, a plan, an SPV, a completed expressway, a nearly built airport, an approved rail line now out to tender, a fab under development. It does not show, and no timeline can show, whether each promise in the chain will be kept on schedule. Dates are evidence of what happened; they are not a guarantee of what happens next.
