Building a highway tunnel through a mountain involves a systematic engineering process: first, heavy machinery clears a staging area at the mountain base; then drilling rigs bore into rock to prepare for controlled blasting, while a steel arch is installed to form the tunnel entrance; inside the mountain, hydraulic drills and explosives break through solid rock to create the tunnel passage; finally, dump trucks and rollers compact crushed stone to build a strong foundation, followed by asphalt pavers laying the smooth road surface, with workers monitoring progress throughout to transform impassable terrain into a vital transportation link.
