magnificent tunnels are located in Europe and Asia. However, a revolution in boring technology might lead to tunnels of unparalleled lengths across the world. Thousand of years ago, humans began to bore tunnels in the earth. Over the ages, our methods have progressed from chiselling and hammering huge granite faces into tunnels. To dig deeper and faster than ever before, we now use tunnel boring machines, or TBMs, which are sometimes known as “moles. Modern tunnelling technology allows for faster and more efficient excavation. Due to this, vast tunnel networks have been constructed, resulting in a substantial reduction in travel time between sites
