The E-road network is a system of international roads in Europe that facilitates cross-border travel and trade. It is designed to connect major cities and regions, ensuring efficient transportation across different countries. The network is marked by a series of routes, each identified by an "E" followed by a number, such as E1 or E40. Established by the United Nations Economic Commission for Europe (UNECE), the E-road network aims to improve road safety and infrastructure. It promotes standardized road signs and regulations, making it easier for drivers to navigate through various countries while enhancing economic cooperation and connectivity across Europe.
