Tunnel

A tunnel is a subterranean or underwater passageway, typically horizontal or inclined, that allows for the passage of vehicles, pedestrians, utilities, or other resources. Constructed by excavation, drilling, or blasting, tunnels often bypass obstacles like mountains, rivers, or built-up areas, providing more direct routes. The structural integrity of a tunnel is paramount, requiring careful engineering and materials to withstand the immense pressure of the surrounding earth or water. They play a crucial role in transportation, resource management, and infrastructure development across the globe, often representing complex feats of engineering.

Tunnel meaning with examples

• The train sped through the dark tunnel, connecting two distant cities beneath the mountain range. Travelers felt a momentary loss of daylight as they passed. The smooth, controlled passage was much quicker than driving the windy roads around the mountain. Engineering and maintenance were top priorities.
• Miners utilized the tunnel to extract valuable resources, risking dangerous underground conditions in their daily work. It was a long process, toiling with hand tools in the dark, confined space. The mine's tunnel extended deep into the earth, following the ore veins. Safety was of utmost importance to prevent accidents.
• During the siege, the soldiers dug a secret tunnel to bypass the enemy's defenses and gain access to the city. The tunnel provided a secret, covert way to the enemy. The tunnel was constructed with great haste under enemy watch. It allowed them to surprise the invaders.
• City officials are planning a new tunnel to alleviate traffic congestion and reduce travel times, aiming to improve transportation efficiency and to improve traffic flow. The tunnel's purpose is to make commute shorter. It's expected to significantly reduce daily commutes. The project faces logistical and budgetary challenges.
