When Saudi Arabia unveiled The Line in 2021, it was pitched as one of the most radical urban development concepts in modern history. A 170km, mirror-skinned linear city slicing across the desert, home to nine million residents, car-free, emissions-free and built on layered vertical infrastructure known as a “city in a line”. It would, its architects said, redefine the very idea of urban life.
Three years later, the project remains one of the central symbols of Crown Prince Mohammed bin Salman’s Vision 2030 transformation agenda. But recent reports of scaled-back construction targets, workforce reductions and financing challenges have raised a critical question: is The Line still proceeding in full — or has the project reached the point where political ambition meets material constraints?
The answer, at least for now, is complicated.
A Vision Designed to Shock
The Line was never intended to be a conventional planning project. Rather, it was designed to demonstrate the kingdom’s willingness to imagine a future unbound by the limits of existing urban form or legacy infrastructure. The city would replace roads with hyperconnected pedestrian corridors, integrate high-speed transit into every neighbourhood, and compress all public services into walkable vertical districts.
The design fit neatly into the narrative Saudi policymakers were promoting: that the kingdom should not merely diversify away from oil, but leap directly into a technologically enabled, globally influential economic model.
Architects, futurists and environmental designers were flown into Riyadh and NEOM headquarters in waves. The project quickly became a symbol of Saudi Arabia’s arrival on the world stage as a producer of ideas, not merely commodities.
Yet the scale was always extreme. For perspective, The Line’s initial plan required constructing more than 50 Manhattans’ worth of high-rise volume, in an environment with no existing city fabric, limited water infrastructure and extreme climate conditions.
Ambition was the point. Deliverability was the question postponed.
Momentum, Investment — and Limits
Over the past two years, progress has been selective rather than uniform. Work accelerated on early infrastructure corridors, logistics hubs, and the spine of the high-speed transit system. Thousands of workers were mobilised; enormous contracting packages were awarded to Saudi and international engineering firms.
Yet insiders say the most visually dramatic component — the continuous 500-metre-tall mirrored walls stretching to the horizon — was always going to be a late-stage element, dependent on structural trials that remain ongoing.
Meanwhile, the global macroeconomic environment has changed. Rising interest rates have increased the cost of capital for megaprojects. Sovereign wealth allocations that were abundant in 2021-22 are now being balanced against domestic employment requirements, defence spending and technology investment. Revenue surpluses driven by high oil prices have narrowed.
Against that backdrop, reports suggest the initial plan to house 1.5 million residents by 2030 has been revised downward to around 200,000–300,000 — still significant, but vastly more manageable.
The Saudi government has not publicly acknowledged a scaling back. But the shift in timelines is increasingly clear: the project is moving from revolutionary narrative to phased pragmatism.
Symbol, Strategy, and Statecraft
The Line was never only about real estate. It was geopolitical theatre: a demonstration that Saudi Arabia intends to define future urban form, not replicate Western or Asian models. It is a signal to global investors — and to its own population — that the kingdom is not permanently tethered to oil economics.
Reducing its scale does not necessarily diminish that message. In some respects, delivering a smaller but realised version of The Line may prove more powerful than continuing to promote a near-mythical megastructure.
The symbolic importance remains:
-
It positions Saudi Arabia as a centre for advanced construction methods and modular engineering.
-
It offers a talent magnet for architects, sustainability technologists and digital infrastructure firms.
-
It reinforces the narrative that the kingdom is shifting from rentier state to diversified industrial economy.
The question is no longer whether The Line will be built, but how much of it, how fast, and in what form.
Lessons from Other Megaproject Paradigms
Comparisons with Dubai’s boom-era developments are inevitable but imperfect. Dubai’s growth was iterative: build, finance, attract, expand. The Line in its original conception was front-loaded: commit scale first, populate later.
Japan’s Metabolist movement of the 1960s, which imagined modular, endlessly expandable megastructures, comes closer as an analogue. Many of those ideas influenced architecture for decades, even though few were completed as drawn.
The Line may end up playing a similar role: a partially realised prototype that shapes global design thinking long after its most ambitious renderings fade.
A Pivot to Deliverability
Contractors working on the project describe a new emphasis on:
-
Segmented development rather than continuous linear construction
-
Mixed-use urban districts instead of a single uniform typology
-
Adaptable massing depending on population uptake and financing cadence
This suggests The Line will emerge first as a series of connected urban nodes — closer to a high-density corridor network than a singular uninterrupted city wall.
If so, the project becomes more plausible and arguably more useful. The kingdom’s population growth, tourism push and industrial diversification efforts all require new cities and new housing, but not necessarily 170km of mirrored walls.
Has the Project “Ended”? No. Has It Changed? Yes.
The Line remains active, funded and politically supported. But the era of audacious reveal videos and speculative renderings is giving way to:
-
construction sequencing
-
infrastructure phasing
-
financial prioritisation
This is less dramatic, but more real.
Saudi Arabia is not abandoning the future-city vision. It is adjusting the tempo to match global economic conditions, investment appetite and engineering reality.
The core narrative persists: that the kingdom intends to build a post-oil economic geography that does not replicate the 20th century city.
If the next decade delivers a functioning first phase of The Line — dense, transit-integrated, shaded, technologically networked — the project will have achieved something unprecedented, even in abbreviated form.
The question now is not whether the linear city will be built exactly as originally marketed. The question is how Saudi Arabia will define success.
And that definition is already shifting from spectacle to substance.
