When trying to identify what is the busiest road in the world, transportation statistics consistently point to Highway 401 in Toronto. Handling nearly half a million vehicles per day, it’s the undeniable leader in the top 5 busiest highway in the world. It serves commuters from surrounding cities, long-distance travelers, and a huge volume of freight trucks, making it a cornerstone of both regional and international transportation.
Interstate 405 in Los Angeles ranks second, infamous for its near-constant congestion and its importance as a connector between residential areas, business centers, and airports. Third is the Chūō Expressway in Tokyo, where high population density and economic activity create constant traffic flow. The fourth spot belongs to I-95, which stretches along the U.S. East Coast, binding together the country’s most densely populated corridor. In fifth place is Highway A100 in Berlin, a short but heavily used route that keeps the city’s traffic in motion. Together, these five highways not only illustrate the meaning of the busiest highway in the world but also highlight the vital role such roads play in keeping global economies moving.
