European highways are an extensive network of roads that connect major cities and regions across Europe. These highways facilitate efficient transportation for both goods and passengers, promoting trade and tourism throughout the continent. They are often designated with the letter "E" followed by a number, indicating their place in the European Agreement on Main International Traffic Arteries (AGR). The Trans-European Transport Network (TEN-T) is a key initiative aimed at improving and integrating these highways. This network enhances connectivity between member states, ensuring that transportation systems are efficient and sustainable. Overall, European highways play a crucial role in the economic and social development of the region.
