Which countries have built the world’s largest highway systems?
Expressways and motorways are among the most important symbols of modern infrastructure. They connect cities, accelerate economic growth, support logistics networks, and transform how people and goods move across countries.
Unlike total road length, which includes local streets and rural roads, expressway networks refer to controlled-access highways designed for high-speed transportation, including motorways, freeways, and national expressways.
As of 2025–2026, China leads the world by a significant margin, operating the longest expressway network ever built, while the United States and major European economies continue to maintain some of the world’s most advanced highway systems.
Here are the Top 10 Countries With the Longest Expressway Networks in the World.
