The Line: Can the $500 Billion City of the Future Really Be Completed?

There are some projects in the world that make you stop and think the moment you hear about them:

“Is this really possible?”

The Line city project, which Saudi Arabia plans to build in the middle of the desert, is exactly one of those projects.

With an estimated budget of $500 billion, a unique design stretching across 170 kilometers, and a completely technology-driven urban model, The Line is considered one of the most ambitious city projects ever designed.

However, projects of this scale always bring major questions.

And everyone is asking the same thing:

Will The Line really be completed, or will it remain one of the biggest city dreams in history?

In this article, we explore what The Line is, why it is being built, why it costs so much, and the biggest challenges standing in the way of the project.

What Is The Line? Saudi Arabia’s City of the Future Project

The Line is the most ambitious part of NEOM, Saudi Arabia’s massive development project located in the northwestern region of the country.

Unlike traditional cities, The Line is built around a completely different concept.

In today’s cities, people usually spread across large areas. Homes, offices, shopping centers, and transportation systems are distributed across many kilometers.

The Line aims to completely change this approach.

The goal is to create a vertically designed city where everything people need can be reached within minutes.

Instead of expanding horizontally like traditional cities, the city will extend in a single straight line.

Planned Features of The Line City

The project includes several impressive features:

• Approximately 170 kilometers in length
• Around 500 meters in height
• Around 200 meters in width
• Capacity for up to 9 million residents
• A car-free city model
• Artificial intelligence-powered city management
• Fully renewable energy systems
• High-speed transportation network

At first glance, the project looks more like something from a science fiction movie than a real city.

When The Line was first announced, many people around the world had the same reaction:

“Can this really be built?”

Why Is The Line City Project Being Built?

One of the biggest reasons behind The Line is Saudi Arabia’s plan for economic transformation.

For decades, Saudi Arabia’s economy has relied heavily on oil revenues.

However, the global energy sector is changing rapidly.

The growth of electric vehicles, increasing investments in renewable energy, and the gradual shift away from fossil fuels have encouraged the country to create new economic strategies.

For this reason, Saudi Arabia launched Vision 2030, a large-scale transformation plan.

Building a New Economy Beyond Oil

The main goal of Vision 2030 is to transform Saudi Arabia from an economy mainly dependent on oil into a global center for:

• technology,
• tourism,
• artificial intelligence,
• finance,
• renewable energy.

The Line has become one of the biggest symbols of this transformation.

The project is not only about building a new city.

It is also designed to attract global attention, investments, and position Saudi Arabia as a leader in future technologies and sustainable urban development.

Why Is the $500 Billion City So Expensive?

When people talk about The Line, one of the first topics that comes up is its enormous cost.

The initial estimated budget for the project is around $500 billion.

This number alone shows the massive scale of the project.

However, many experts believe the final cost could increase over time due to the complexity of building a city of this size.

There are several reasons behind the huge price tag.

Building an Entire City in the Middle of the Desert

Most cities grow by using existing infrastructure.

They already have:

• roads,
• electricity networks,
• water systems.

But The Line is being built from scratch in an empty desert region.

This means developers must create everything from the beginning:

• energy facilities,
• water systems,
• transportation networks,
• communication infrastructure,
• residential areas.

Building all of these systems simultaneously significantly increases costs.

One of the Largest Glass Facades Ever Built

One of The Line’s most recognizable features is its appearance.

The project is designed as a massive structure covered with reflective glass and mirror-like surfaces on both sides.

However, creating such a huge facade system presents enormous engineering challenges.

The production, transportation, installation, and long-term durability of millions of glass panels require advanced technology and planning.

Why Is The Line Construction So Difficult?

Projects that look incredible on paper often face unexpected challenges in reality.

The Line is one of the biggest examples of this.

The Desert Climate Is a Major Challenge

The region where The Line is being built has one of the harshest environments in the world.

During summer months, temperatures can reach 45–50°C.

This creates serious challenges regarding:

• worker safety,
• working hours,
• material durability.

Building a massive city in the desert is far more complicated than constructing a normal urban development.

Logistics Challenges

Building a city requires millions of tons of materials.

Concrete, steel, glass, and other construction materials must be transported to the remote location.

But logistics are not limited to construction materials.

Thousands of workers also need:

• accommodation,
• transportation,
• daily services.

Managing such a large workforce requires a massive organizational effort.

Why Are Experts Concerned About The Line Project?

The Line is not only criticized because of its cost.

The project’s unusual design has also raised questions.

A city of this size and structure has never been built before.

What Will Life Be Like in a 170-Kilometer City?

The biggest question is:

Will people really want to live in a city stretching 170 kilometers in one straight line?

Traditional cities develop naturally through different neighborhoods and communities.

The Line proposes a much more controlled and highly concentrated lifestyle.

How this will affect people’s social lives and daily experiences remains uncertain.

Environmental Concerns Around The Line

The massive glass exterior of the project has also raised environmental concerns.

Experts are questioning its possible effects on:

• bird migration routes,
• desert ecosystems,
• energy consumption.

Because a structure of this scale has never been tested before, its long-term environmental impact is still uncertain.

When Will The Line Be Completed?

When the project was first announced, expectations were that construction would move very quickly.

However, as the true scale of the project became clearer, the challenges also became more obvious.

Completing such a massive structure all at once appears extremely difficult.

For this reason, The Line is expected to be developed in stages.

Will The Line Be Built in Phases?

Large-scale projects often progress through multiple phases.

This approach helps:

• control costs,
• solve technical challenges,
• manage investment risks.

A similar strategy is expected for The Line.

The first sections will likely be completed before the city continues expanding over time.

Could The Line Become the City Model of the Future?

The Line is not just a building project or a new city.

It is also a massive experiment testing how humans might live in the future.

Some of the innovations planned for the project include:

• AI-powered management,
• car-free living,
• smart transportation,
• zero-carbon goals,
• digital city infrastructure.

If successful, The Line could influence urban planning around the world.

Will The Line Be Successful?

Today, nobody knows the exact answer.

Some people see The Line as the future model of urban living.

Others believe the project is too ambitious and carries significant risks.

The truth is:

The success of The Line will not depend only on money.

It will require:

• advanced engineering solutions,
• sustainable financing,
• long-term management.

Conclusion: Is The Line the City of the Future or a Massive Dream?

The Line is one of the most ambitious urban projects in human history.

With its $500 billion budget, futuristic architecture, and technology-focused design, it has already become a landmark project of the 21st century.

However, the scale of the project is also its biggest challenge.

Rising costs, engineering difficulties, environmental debates, and questions about human adaptability continue to create uncertainty.

Whether The Line will be fully completed remains unknown.

But one thing is certain:

Whether it succeeds or fails, The Line will remain one of the most talked-about city projects of the 21st century.
