Middle mile refers to the transportation phase in logistics that connects suppliers or manufacturers to distribution centers, warehouses, or retail locations. It plays a critical role in the supply chain by bridging the gap between the initial production stage and the last-mile delivery to customers. Middle mile transportation often involves trucks, rail, or other freight methods to move goods efficiently and cost-effectively. In middle mile logistics, optimizing routes and transit times ensures smooth operations and timely delivery to the next stage. For businesses, efficient middle mile logistics is essential for maintaining inventory flow and reducing overall transportation costs.
