The desert remembers everything. Long after the drones have stopped circling, after the concrete mixers have gone silent and the PR videos have slipped out of fashion, the sand still holds the faint outlines of our wild ideas. In the northwest corner of Saudi Arabia, where the mountains lean into the Red Sea and the wind tastes of salt and dust, the traces of the most audacious one are still there: survey markers, half-built foundations, abandoned worker camps, and a wound-like straight line cut across an ancient landscape. This is where a 100-mile “linear city” was supposed to rise like a mirror-walled mirage from the dunes—until, almost as quietly as it was announced with fanfare, the dream began to shrink, stall, and finally dissolve.
The Dream That Promised to Rewrite the Desert
When Saudi Arabia unveiled its plan for a 170-kilometer long, glass-walled megacity in 2021, it didn’t feel like an urban project; it felt like a science-fiction pitch with an unlimited budget. The Line, as it was called, would slice through the desert in a ruler-straight strip: 200 meters wide, 500 meters high, flanked by mirror surfaces that would reflect sky and sand like a shimmering tectonic plate.
Inside those walls, planners promised, there would be no cars, no streets, no fossil fuel emissions. Just a high-speed spine of transit that could whisk anyone from point A to B in 20 minutes, vertical gardens climbing toward the desert sun, and public spaces floating somewhere between mall, park, and digital game. Nine million residents, they said, would call it home. It would be powered by 100% renewable energy. AI would manage water, waste, movement, and temperature. The city would leave “95% of nature untouched.”
It was more than a plan. It was a narrative, wrapped in glossy renderings and cinematic videos: the kingdom reborn as a post-oil, future-forward civilization, led by a restless crown prince eager to prove that the wealth of the last century could purchase the relevance of the next one.
For a while, the world played along. The Line appeared on magazine covers, in TED-like presentations, and in breathless explainer videos. Consultants flew in. Architects pitched ideas. Engineers ran simulations. The desert, patient as always, watched men in neon vests pound stakes into its skin and spray fluorescent paint across wadis and gravel plains.
The Quiet Shrinking of a Loud Vision
Then something shifted. At first, it wasn’t obvious. Mega-projects evolve all the time, especially those dreamt up at breakneck speed. But the edges of the story began to fray. Construction advanced far more slowly than the marketing animations. The mirrored walls that were supposed to stretch over the horizon stalled after short segments and excavated trenches. A few workers spoke, anonymously, of sudden pauses and unexplained delays.
In early 2024, whispers became numbers. Insiders and analysts began talking about “revised timelines” and “phased build-outs.” The vision of a 100-mile city was quietly resized: first to a fraction of its length, then to a handful of segments that, depending on who you believed, might someday connect—or might forever remain isolated shards in the sand.
Billions had already been spent: on planning, salaries, global marketing campaigns, imported expertise, heavy machinery, desalination, and early infrastructure. In project documents, the broader NEOM initiative was estimated in the hundreds of billions, potentially nudging a trillion dollars. The Line—once the headline act—was suddenly framed as an “evolving concept,” a “pilot for future urbanism,” or simply a “component” among many, rather than the literal backbone of the future.
No single announcement declared its downsizing. There was no somber press conference where a spokesperson said, “We miscalculated.” Instead, in that famously opaque way of mega-projects, the dream was reduced behind closed doors and emerged, thinner and more tentative, into a world that had already moved on to the next spectacle.
A Mirage Built on Sand and Spreadsheets
On paper, The Line was an elegant answer to a messy question: how do you build a city that burns no fossil fuels, consumes minimal land, and inspires a world drowning in traffic and smog? In practice, the questions multiplied.
Urban designers wondered about livability in a vertical canyon hundreds of meters deep, with sunlight blocked for much of the day and wind tunnels forming between the mirrored walls. Environmental scientists warned of the damage such a massive linear footprint could inflict on fragile desert ecosystems, wildlife migration routes, and ancient cultural sites. Economists quietly asked what would actually drive nine million people to live there, beyond state decree and corporate incentives.
To understand the scale of the ambition, the financing, and the eventual retreat, it helps to see it laid out simply. Behind the soaring rhetoric was an equation of land, money, time, and political will—an equation that never quite balanced.
| Aspect | Original Vision for The Line | Emerging Reality |
|---|---|---|
| Planned Length | ~170 km (100+ miles) | A much shorter built segment; rest “under review” |
| Population Target | 9 million residents | Scaled back early targets; real population remains uncertain |
| Cost Estimate | Part of broader NEOM budget up to hundreds of billions | Billions already spent; full funding in doubt |
| Timeline | Key stages by 2030, full build longer-term | Deadlines softened; milestones moved or dropped |
| Environmental Claims | Net-zero, 95% of nature “preserved” | Displacement of wildlife and local communities reported; true impact unclear |
The table doesn’t capture the human texture of it all: the foreign consultants working 14-hour days in glass offices far from the site, feeding a machine of endless PowerPoints; the thousands of migrant laborers bussed into camp after camp; the local tribes, some displaced from ancestral valleys whose names never appeared in the glossy brochures.
Listening to a Landscape That Was Never Asked
To imagine the cost of a project like The Line, you have to zoom out from budgets and look instead at the land itself. The proposed route cuts through a region of rugged, under-studied beauty: basalt plateaus, hidden springs, seasonal streams that roar to life after rare storms, and migration corridors for birds traveling between Africa and Eurasia.
On winter mornings, the air here can be unexpectedly cold, smelling of damp stone and acacia resin. Ibex once picked their way along narrow ledges, and wolves padded across the gravel fans by night. Bedouin moved along these same paths for generations, following rains, grazing animals, and stories. Underfoot, the desert holds traces of older civilizations—petroglyphs, forgotten tombs, shards of pottery whose makers never imagined glass walls blotting out the horizon.
From above, The Line was drawn as a clean stroke through this complexity, as if the land were a blank page rather than a densely written manuscript. Environmental impact assessments, to the extent they were conducted and disclosed, came late and in fragments. Some biologists warned that the linear barrier could act like an artificial mountain range, slicing habitats and forcing species to either adapt, detour, or disappear.
Meanwhile, bulldozers began leveling ground. Satellite images showed scars widening, camps expanding, access roads branching out into places where, only a few seasons before, you could walk all day without seeing a single machine. The silence of the proposal—no public debate, no open environmental hearings—was matched only by the silence of the cancellation. Decisions as vast as the sky were made in rooms with locked doors.
When Utopias Become Expensive Experiments
Every era has its monuments to ambition. Some succeed, some fail, and some linger half-built, slowly dissolving back into the elements that resisted them. The partial retreat from The Line doesn’t just raise questions about one project; it highlights a deeper unease about how we, as a planet, are trying to buy our way out of the ecological crisis.
The promise was seductively simple: build one perfect, hyper-efficient city and show the world that the future can be both luxurious and sustainable. But desert ecology and human society aren’t static game boards waiting for a new rule set. They are messy, adaptive, full of memory and resistance.
Critics, from urban planners to human rights groups, argue that the story of The Line is not just about technical miscalculation; it’s about a mindset. When you have enough money and political power, it becomes dangerously easy to confuse a rendering with reality. Questions like “Who will live here? What will they do? What will it feel like to raise a child in a 500-meter-deep corridor?” get sidelined by questions like “How fast can we announce this?” and “How iconic will it look from space?”
Billions of dollars later, as the project contracts, those early questions echo louder. In a world of acute climate anxiety, the temptation to leap toward shining megastructures is real. But so is the risk that we end up building monuments to ego, not solutions that actually fit the grain of the land and the needs of the people who live on it.
Who Answers for a Fading Megacity?
“Who will answer for this?” has become the quiet refrain among critics watching The Line’s slow retreat. It’s not just about one country; it’s about accountability in the age of planetary-scale projects.
When a $10 million project fails, there are audits, sometimes lawsuits, and often public scrutiny. When a project worth tens or hundreds of billions falters—stitched to national pride, wrapped in state secrecy—the usual tools of accountability grow blunt. Parliamentary debates are limited. Independent media access is restricted. Whistleblowers risk far more than career damage.
There are at least four layers of responsibility that keep resurfacing in conversations about The Line:
- Political leadership: Those who championed a 100-mile city as a symbol of the nation’s future, fast-tracked it, and tied it tightly to their own prestige.
- Global consultants and firms: The architects, engineers, and branding experts who lent their credibility to a vision whose environmental, social, and economic assumptions were often precarious.
- Corporate partners and investors: Entities that saw opportunity, ignored warning signs, then quietly stepped back once the shine began to fade.
- International institutions: Organizations that echoed the rhetoric of “sustainable, smart cities” without pressing hard on the ecological and human costs.
Yet as the excavators idle and budgets are quietly reallocated, those responsible will likely offer only carefully drafted statements—if they speak at all. There may be talk of “phasing,” “strategic realignment,” and “lessons learned,” but rarely of the specific birds that lost their nesting sites, the families relocated from valleys now mapped only as grid references, or the young engineers who poured their early careers into a blueprint that will never be built as promised.
The Desert as a Teacher, Not a Blank Slate
Out on the ground, far from the air-conditioned war rooms where megacities are imagined, the lessons are older and quieter. Traditional desert communities learned long ago that the land does not yield easily to straight lines. Paths curve around dunes, wells are dug where the earth allows, and settlements grow in broken, organic clusters shaped by wind, water, and shade.
In this light, the most radical thing about The Line was not its height or its length; it was its refusal to bend. That refusal—its insistence on total linearity—may be the purest metaphor for why it stumbled. It did not listen, either to the land or to the full range of human voices that might have reshaped it into something smaller, slower, and wiser.
There is a different kind of future city hidden inside the failure of The Line, if we pay attention. It might look less like a mirrored monument and more like a series of compact, walkable settlements stitched together with efficient transit, integrated carefully with topography, water, and existing communities. It might accept imperfection: some cars, some messiness, some unplanned growth. It might be built not as a spectacle, but as a patient layering of infrastructure and culture over time.
The desert, for all its reputation as empty, is full of such incremental stories: an extra room added to a stone house after a good year of grazing; a new cistern dug when a spring changes course; a village’s slow migration from one slope to another as the winds and markets shift. These stories are inefficient by the standards of global headlines—but they endure.
What Remains After the Mirage Fades
So what happens now, in that strip of northwestern Saudi Arabia where a city of the future was supposed to unfurl like a roll of mirrored film across the sand?
Some of the construction will likely remain—converted into smaller, more conventional developments, luxury enclaves, logistics hubs, or research centers that still fit within the broad NEOM umbrella. The brand is too large, the sunk costs too deep, for the entire enterprise to vanish. Workers will keep building something; the question is no longer “Will The Line exist?” but “In what diminished, reimagined form will it survive?”
For environmentalists and community advocates, the task will be to salvage what can be saved: to push for proper protection of remaining habitats, for transparency about what was lost, and for meaningful consultation before the next iteration of the dream is sketched out. For policymakers around the world, watching from afar, the larger lesson is painfully relevant: sustainability cannot just be declared at the end of a glossy video. It has to be tested, doubted, revised—and above all, rooted in the ecological and social realities of a place.
On some future evening, long after the headlines have shifted to other mega-schemes and new acronyms, the sun will set behind those unfinished walls, throwing long, cold shadows over the desert floor. Wind will push sand into cracks where steel meets stone. A fox will pause at the edge of the disturbed land, sniff the scent of concrete and diesel, and veer a little wider around the obstacle. Life, as it tends to do, will adapt cautiously to what has been done in its name.
The desert will remember The Line, as it remembers every attempt to master it with straight edges and certainty. The question that lingers for the rest of us, far beyond Saudi Arabia’s borders, is whether we will remember too—remember not just the spectacle of a 100-mile dream, but the soft collapse that followed, and the price paid by a place that was never asked what kind of future it wanted.
Frequently Asked Questions
Was The Line officially cancelled?
There has been no dramatic, formal cancellation announcement. Instead, official language has shifted toward “phasing,” “scaling,” and “prioritizing segments.” In practice, this means the original 100-mile vision has been quietly abandoned in favor of a far smaller, uncertain build-out.
How much money has been spent on The Line so far?
Exact figures are tightly controlled, but independent estimates suggest that many billions of dollars have already been invested in planning, infrastructure, land preparation, and early construction, all as part of the broader NEOM initiative, which itself carries a projected budget in the hundreds of billions.
What were the main criticisms of The Line?
Critics raised concerns about environmental damage to fragile desert ecosystems, displacement of local communities, questionable livability inside a narrow, vertical corridor, lack of transparency, and doubts about the economic logic of attracting millions of residents to a remote, hyper-controlled urban experiment.
Why is it so hard to hold anyone accountable?
The Line is a state-driven project in an environment with limited public oversight, restricted media, and centralized power. Major decisions are made at the highest political levels, often shielded from open scrutiny, while global firms involved are protected by contracts and nondisclosure agreements.
What can other countries learn from this experience?
The main lessons are that sustainability cannot be added as branding after the fact; that genuine consultation with local communities and scientists is essential; and that transformative urban projects should grow from the specific realities of a landscape, not be imposed as rigid, symbolic gestures onto it.
