Evaluating the Impact of Land Bridge as a Complementary Corridor to the Suez Canal
This paper proposes and applies a methodological framework combining multimodal transport modeling and generalized-cost analysis to demonstrate that land-bridge corridors can serve as competitive, resilient alternatives to the Suez Canal for high-value intercontinental freight, offering strategic insights for the development of emerging Eurasian trade routes.

For more than a century and a half, the Suez Canal has served as the great artery of global trade, a narrow waterway cutting through Egypt that allows ships to travel between Asia and Europe without having to sail all the way around the southern tip of Africa. This shortcut saves roughly three thousand nautical miles and about nine days of travel time, handling nearly a third of all the world's containerized cargo. Yet, this single, narrow passage is also a point of extreme vulnerability. When a massive ship gets stuck, as happened in 2021, or when political unrest threatens the safety of the waterway, the entire global supply chain can grind to a halt, costing billions of dollars and disrupting the flow of goods that modern life depends on. As the world's population grows and trade volumes are projected to triple by the middle of the century, relying on just one route feels increasingly risky. This has led logistics experts and governments to look for alternatives, specifically asking whether trains and roads could offer a faster, more reliable way to move goods across the continents, acting as a backup or a complement to the ships.
A team of researchers from Roma Tre University in Italy has taken a deep dive into this question, building a detailed model to test how three different overland routes might compete with the traditional sea journey. They did not just guess; they constructed a mathematical framework that calculates the total "generalized cost" of moving a container. This concept combines the actual money spent on fuel, tolls, and fees with the value of the time the cargo spends in transit. For many high-value goods, time is money; a delay of a few days can cost a company more than the extra expense of a faster route. By weighing these factors together, the researchers could determine which path a shipper would logically choose under different conditions. They focused their analysis on the year 2040, a time when they expect new railway infrastructure to be fully operational and the Suez Canal to potentially face capacity limits.
The study examined three specific corridors that represent different strategies for connecting Asia to Europe. The first is the Eurasian Land Bridge, a long-standing rail network that runs entirely over land from China through Central Asia and Russia to Europe. The second is the India–Middle East–Europe Economic Corridor, a complex plan involving ships and trains that would weave through the Gulf, Israel, and Jordan. The third is the Iraqi Development Road, a newer proposal that would bring goods from a port on the Persian Gulf, move them by rail and road through Iraq and Turkey, and then connect to the European rail network. The researchers compared these three against the standard route: a ship passing through the Suez Canal and then traveling by land to its final destination in Europe. They tested these routes across seven major city pairs, such as Shanghai to Duisburg in Germany or Shanghai to Istanbul in Turkey, to see how geography and speed would influence the choice.
The results of their simulations reveal a clear hierarchy of potential. The study suggests that the India–Middle East–Europe Economic Corridor, despite its ambitious design, is unlikely to capture a significant share of traffic. The researchers found that its structure, which requires moving cargo from a ship to a train and then back to a ship, creates too many stops and transfers. These extra steps add time and cost, making it less attractive than a direct sea voyage for most goods. Similarly, the fully land-based Eurasian Land Bridge showed limited competitiveness. While it is faster than the sea route, the high cost of running trains over such vast distances, combined with the logistical headaches of crossing multiple borders with different railway systems, keeps it from being a dominant choice. It remains a viable option only for a very specific type of cargo that is extremely time-sensitive and destined for Eastern Europe.
The most promising alternative emerged as the Iraqi Development Road. This route offers a hybrid solution: it uses a ship for the long ocean leg to a new port in Iraq, then switches to a train for the journey through the Middle East and into Europe. This combination allows it to cut the total travel time significantly compared to the Suez route, particularly for destinations in Southeastern Europe, Turkey, and the Balkans. In the researchers' models, this corridor could capture nearly all the freight traffic for cities like Sofia, Bucharest, and Istanbul, where the time saved on the overland portion outweighs the higher cost of the train. For other destinations further west, like Germany or France, the traditional Suez route remains the preferred choice because the extra distance traveled by rail to reach those cities negates the time savings.
However, the study also highlights that this competition is not static; it depends heavily on the conditions of the world around it. The researchers ran a series of sensitivity tests to see how the results would change if key factors shifted. They found that if the Suez Canal faces delays due to congestion or geopolitical trouble, the overland routes become much more attractive. Even a small increase in the time it takes to sail through the canal can tip the balance, causing a surge in demand for the faster land alternatives. The value of time also plays a crucial role; as goods become more expensive and supply chains demand faster delivery, shippers are more willing to pay the premium for the speed of a train. The study concludes that while no single land bridge will replace the Suez Canal, which remains the most efficient path for the vast majority of goods, routes like the Iraqi Development Road can serve as a vital safety valve. They offer a way to diversify the global network, ensuring that if the waterway is blocked or slowed, the flow of commerce can continue through the land, making the entire system more resilient against the shocks of the future.
