The next chapter of Indonesia’s infrastructure: From concrete to a high-performing system

Over the past decade, Indonesia’s infrastructure drive has centred on roads and transport. To sustain the nation’s progress, the next phase must adopt a different approach – shifting away from concrete-heavy expansion towards building a high-performing and integrated system, write experts from management consultancy Altha.

Throughout the last decade, Indonesia has concentrated resource extensively in roads and transport infrastructure, reaching for growth, reduced costs, and accessibility across the nation. However, despite this significant focus in construction, metrics of current economic performance tell a more complex story.

Freight and logistic costs in Indonesia – a critical component to drive competitiveness – is above levels typical in advanced economies and regional peers, even after recent declines measured domestically, hovering around 23–24% of GDP, Meanwhile, Indonesia’s performance on the World Bank’s Logistics Performance Index slipped from rank 46 in 2018 to rank 61 in 2023 (World Bank), suggesting persistent inefficiencies in moving goods and services.

At the same time, economic growth has remained steady but unspectacular: the economy expanded by roughly 5% in 2023, in line with recent trends, but still below the ambitious 8% target set by policymakers (Government). Productivity growth – the engine of long-term prosperity – has been relatively sluggish compared with some ASEAN peers, with total factor productivity trends trailing regional benchmarks (OECD).

These patterns raise a critical question: Why isn’t massive road building translating into the productivity gains Indonesia needs?

This answer lies not in rejecting infrastructure, but in recognizing that roads alone do not generate productivity – systems do. In today’s economy, productivity depends on integrated transport networks, efficient logistics, urban mobility, land use coherence, and digital connectivity. When these elements are misaligned, even major road investments can fall short of their promise.

What Indonesia needs now is a shift from expansion to performance, from counting kilometers built to measuring economic outcomes – and a strategy that aligns infrastructure with the realities of a modern, diversified economy.

Snapshot of Indonesia’s infrastructure challenges

To understand why road investment is delivering mixed productivity results, it is necessary to first understand the structural complexity Indonesia is operating within.

Indonesia is not a single, contiguous economy. It is a nation of more than 17,000 islands, with economic activity heavily concentrated in Java, while resource production, manufacturing growth, and consumption are increasingly dispersed across Sumatra, Kalimantan, Sulawesi, and eastern Indonesia. This geography makes connectivity essential – but also inherently difficult.

Over the past decade, road construction has focused primarily on:

• Inter-city toll roads, especially along Java’s northern and southern corridors
• Access roads linking industrial estates, ports, and airports
• Strategic national projects aimed at reducing regional inequality

These investments have delivered clear, visible improvements. Travel between major cities is faster. Logistics routes are more continuous. Regions that were once isolated are now physically connected to markets.

At the same time, Indonesia’s economy itself has been changing. Urbanization has accelerated, with metropolitan regions like Greater Jakarta absorbing millions of workers. Manufacturing and services increasingly depend on reliable, time-sensitive movement, not just distance reduction. E-commerce, just-in-time production, and urban labor markets place far greater emphasis on predictability, last-mile efficiency, and congestion management than on highway length alone.

This creates a fundamental tension. Many of Indonesia’s infrastructure challenges are no longer about access, but about coordination:

• Roads expand faster than land-use planning adapts
• Freight competes with commuters in dense urban corridors
• Ports, industrial zones, and cities are connected physically, but not operationally
• National investments interact unevenly with local governance and incentives

In this context, adding road capacity often solves yesterday’s problem while leaving today’s bottlenecks untouched.

Why roads made sense – but that logic is fading

For much of its development trajectory, a road-centric infrastructure strategy was not only logical for Indonesia – it was necessary.

As a geographically fragmented nation with large regional disparities, Indonesia faced a fundamental constraint: physical access. Roads reduced isolation by connecting producers to markets and supporting urbanization and industrial expansion. In this context, the expansion of road networks delivered clear economic returns and helped unify the national economy.

This strategy rested on a simple logic, improving connectivity means reduced travel time this will lead into a raise productivity.

For many years, this logic broadly held. But Indonesia’s economy has evolved – and the conditions that once made road expansion highly productive are no longer dominant.

Most major economic centers are now physically connected. Urbanization has accelerated, vehicle ownership has risen, and economic activity has shifted toward sectors that depend less on distance and more on reliability, coordination, and time certainty. Manufacturing clusters, services, and the digital economy are increasingly sensitive to urban congestion, last-mile delays, and system inefficiencies rather than highway length alone.

At the same time, new road capacity increasingly generates induced demand. Faster corridors attract more vehicles, encourage longer commutes, and fuel outward urban expansion. Travel times stabilize rather than fall. Congestion shifts location instead of disappearing. The economic return of each additional kilometer declines.

Roads still matter. But they now function as inputs, not outcomes. Without integration into a broader mobility, logistics, and land-use system, additional capacity delivers diminishing economic returns.

Indonesia’s infrastructure challenge has therefore entered a new phase. The question is no longer how much to build, but how to convert existing and future assets into sustained productivity gains.

Productivity is a system, not a surface

The limitations of road-centric infrastructure strategies point to a deeper issue: productivity does not emerge from individual assets, but from how well an entire system functions and operates.

In Indonesia’s current stage of development, productivity depends less on how fast vehicles can move along highways, and more on how reliably people, goods, and firms can interact within dense economic environments. Roads are part of that equation – but only one part.

Continuing to prioritize road expansion carries opportunity costs. Capital becomes concentrated in large projects, crowding out smaller, higher-return interventions. Public transport, intermodal logistics, and digital systems lag behind. Maintenance liabilities grow. Benefits accrue unevenly, favoring private vehicle users while leaving many workers exposed to long, unreliable commutes.

Perhaps most importantly, road-heavy strategies create path dependency. Once cities and travel behavior adapt to sprawl and vehicle dependence, reversing course becomes expensive and politically difficult.

These trade-offs signal diminishing returns – not failure, but misalignment. If Indonesia’s next productivity gains depend on system performance rather than physical expansion, infrastructure strategy must evolve accordingly. This does not mean building fewer roads – it means making existing and future infrastructure work smarter through outcome-based decisions and digital enablement.

The infrastructure playbook

At Altha, we believe a more effective infrastructure playbook for Indonesia rests on five principles.

1) Shift from assets to outcomes
Move beyond measuring success by kilometers built or projects completed. Instead, track outcomes that matter to productivity: travel-time reliability, logistics costs, labor access, and freight predictability.

Infrastructure should be evaluated by economic performance, not physical scale. This shift requires performance monitoring and analytics that allow policymakers to see how infrastructure performs in daily use.

2) Invest where bottlenecks constrain productivity most
Prioritize interventions at points of friction – urban entry corridors, logistics access to ports and industrial zones, last-mile freight, and congested labor catchments. Many of these yield higher returns than large greenfield road projects. Informed decisions need to be made by utilizing historical digital insights

3) Integrate land use, transport, and logistics planning
Infrastructure works best when spatial planning, housing policy, and economic development move together. Aligning these decisions reduces unnecessary travel demand and allows roads to support clustering rather than sprawl.

4) Optimize before expanding
Maintenance, traffic management, demand pricing, freight prioritization, and digital coordination can unlock latent capacity in existing assets at a fraction of the cost of new construction. Performance upgrades often outperform expansion in mature corridors.

5) Strengthen institutional coordination
Productivity gains increasingly depend on how well agencies collaborate. Aligning incentives across transport, urban planning, ports, and local governments can transform infrastructure from a collection of projects into a functioning economic system.

Taken together, these principles reframe infrastructure as a productivity platform – one that enables people and firms to interact efficiently – rather than as a series of standalone investments.

Conclusion

Indonesia’s infrastructure journey is often described in terms of scale: kilometers of roads built, projects delivered, and capital deployed. These achievements matter. They have reduced isolation, improved connectivity, and laid the foundation for economic growth.

But the next chapter will be defined by something less visible. As Indonesia’s economy becomes more urban, more integrated, and more time-sensitive, productivity will depend less on how much infrastructure exists – and more on how well it works as a system.

The infrastructure dilemma Indonesia now faces is not whether to build, but how to convert investment into lasting economic capability.
