A tunnel is an underground passage that is typically built for transportation, such as roads, trains, or utilities. It can also be used for water flow or as a way to bypass natural obstacles like mountains or rivers. Tunnels are usually dug or drilled through the earth or rock, and they can vary in length, width, and purpose. They are often lined with concrete or steel to prevent collapse. Tunnels are an essential part of infrastructure, providing safe and efficient routes for people and goods. Some tunnels are open to the public, while others are used only for specific purposes, like mining or utilities.
