Tunnel systems

Tunnel systems are underground passages designed for transportation, utilities, or storage. They are constructed beneath the earth's surface using specialized machinery and techniques to navigate through rock or soil. These tunnels can serve roads, trains, subways, water or sewage systems, and even ventilation or communication networks. Built with safety and efficiency in mind, they help reduce surface traffic, protect infrastructure, and facilitate urban development. Engineering challenges include dealing with differing geology, water ingress, and ensuring structural stability. Overall, tunnel systems are vital underground networks that support modern infrastructure and mobility.
