As global demand for freight transport continues to rise, road networks are becoming more congested, emissions are increasing, and businesses face mounting delivery challenges. With the transportation sector responsible for 23% of global energy-related CO₂ emissions, finding innovative solutions to ease pressure on roads while maintaining efficient supply chains is of utmost importance.
One solution gaining traction is underground freight transport – a system of tunnels designed to move cargo efficiently while simultaneously reducing congestion and environmental impact on our roads. But is this a reality or a pipe dream (excuse the pun)? And are we ready to embrace it?
Why underground freight transport?
The concept of underground freight tunnels isn’t new, but advances in infrastructure and technology are making them more feasible. These systems could provide:
- Reduced congestion: Taking freight movement below ground frees up roads for passenger traffic, reducing delays and improving transport efficiency.
- Lower emissions: Freight accounts for a large portion of global transport-related CO₂ emissions. With less congestion on the roads, underground systems could help reduce pollution and environmental impact.
- Faster, more reliable deliveries: Unlike road freight, underground tunnels wouldn’t be affected by traffic jams or bad weather, which, as we all know, can cause delays and accidents.
While the potential is clear, challenges remain, including high costs, technical complexities, and, as with any large-scale project, an abundance of regulations.
Nevertheless, several projects are already taking steps to make it a reality.
Underground freight networks are already underway
Around the world, several projects are proving that underground freight transport is transitioning from an idea to reality.
The Netherlands – “the road to the future” (smart highway project)
The Netherlands has explored integrating trucks into tunnel systems as part of their smart highway projects. While this is not entirely focused on underground freight tunnels, it envisions efficient movement for trucks traveling through tunnels designed to improve traffic flow and reduce congestion, all while using innovative infrastructure to support sustainable transport.
The UK – “the trans-Pennine tunnel” proposal
In the UK, the Trans-Pennine Tunnel project is a proposal aimed at reducing road congestion and providing a smoother, faster route for freight, especially for trucks. This tunnel system would alleviate pressure on the existing road networks and help reduce CO₂ emissions. The tunnel is also expected to allow for heavy trucks to bypass surface-level congestion, improving logistics efficiency.
California – “the tunnel transportation system” by the Boring company
Elon Musk’s The Boring Company has proposed an underground transportation system that could involve trucks traveling through tunnels on electric skates. This would allow freight to be transported rapidly through tunnels, bypassing road traffic and congestion. The proposal aims to reduce emissions while offering a sustainable and efficient solution for goods movement.
The economic impact for businesses
Beyond the environmental and logistical benefits, underground freight networks could provide tangible economic advantages for businesses. Key benefits include:
- Long-term cost savings: By reducing surface congestion, businesses could lower fuel consumption and reduce the need for extensive vehicle maintenance. For example, companies that rely on long-haul trucking could see significant savings in fuel costs, while fewer repairs would cut operational expenses.
- Increased efficiency and faster deliveries: Underground networks would allow goods to move without the delays caused by traffic, accidents, or weather disruptions. This would lead to more predictable delivery times, enabling businesses to optimize their inventory, reduce storage costs, and improve overall supply chain efficiency.
- Reduced economic loss from congestion: In the UK alone, traffic congestion costs businesses £6.9 billion annually due to delays. With underground freight systems, companies would benefit from faster, uninterrupted transport, reducing both the time and money lost in gridlock.
- Better fleet management and resource allocation: With fewer delays, businesses can better plan deliveries and allocate resources efficiently, ultimately lowering costs associated with last-minute changes, overtime, or additional vehicle rentals. Additionally, businesses with more consistent delivery schedules would see improved customer satisfaction and stronger partnerships.
The long-term economic benefits—reduced congestion, improved efficiency, and cost savings for businesses—highlight the value of underground freight systems in shaping the future of logistics.
Digging deeper: the challenges with underground freight
Despite its promise, underground freight transport faces significant challenges:
- High initial investment: Building extensive underground networks requires substantial upfront costs, which can be a major barrier for governments.
- Complex urban planning: Tunnels must be integrated into existing infrastructure without disrupting city layouts, requiring careful planning and coordination.
- Regulatory approvals: Underground logistics systems require new regulations covering land use, transport safety, and operational standards.
These challenges are significant, but if successful, the benefits could far outweigh them.
The future of freight: are we ready?
As cities grow and online shopping continues to surge, traditional freight transport is under increasing pressure. Roads are busier than ever, leading to unpredictable delivery times, and businesses are feeling the strain. Underground freight networks offer a real alternative—one that keeps goods moving without adding to surface traffic.
With several pilot projects and feasibility studies underway, the concept of underground logistics is being tested to determine its potential to reshape supply chains and improve freight transport.
The big question now is: who’s next? The demand for smarter freight solutions has never been higher. This isn’t about replacing traditional freight—it’s about rethinking how goods move in a way that’s smarter, greener, and built for the future. Will other governments and industries step up?
