The Suhua Highway has always been a precarious dialogue between the ambition of man and the restless spirit of the Central Mountain Range. It is a road that clings to the edge of the world, carved into the marble and greenery that defines Taiwan’s eastern face. There, the Pacific Ocean provides a constant, rhythmic backdrop to the transit of thousands, but the mountain above remains the silent arbiter of the journey, occasionally reminding the travelers below of its ancient, shifting presence.

Early on a Sunday morning, while the rest of the island was draped in the quietude of sleep, a portion of the mountain decided to move. It was not a grand collapse, but a localized exhale—a rockfall that struck the Daqingshui Tunnel with the sudden, blunt force of nature. A single stone, measuring nearly three meters, became a monument to the unexpected, piercing the steel roof of the open-cut structure and reclaiming a piece of the human path for the earth.

There is a visceral quality to the aftermath of a rockslide; the scent of crushed stone and wet earth lingers in the air, a sensory ghost of the event itself. For the workers who arrived in the pre-dawn hours, the task was one of negotiation. They worked within the ribs of the tunnel, clearing the debris and assessing the integrity of the roof, their headlights cutting through the dust like small, hopeful stars against the grey gloom of the damaged shed.

Traffic, usually a steady stream of commerce and tourism, was reduced to a singular, alternating pulse. One lane remained open, a narrow thread of connectivity that required the patience of the travelers and the vigilance of the flagmen. To drive through the tunnel now is to pass under a canopy of temporary repairs, a reminder that the structures we build to protect us are themselves subject to the whims of the rain and the pull of the slope.

The Highway Bureau’s response was one of methodical restoration, utilizing aerial photography to peer into the places where human eyes cannot easily reach. Looking at the slope from above, one sees the scars of the landslide as fresh gashes in the green velvet of the mountainside. The plan to install an energy-dissipating curtain—a net made to catch the falling weight of the world—is a testament to our ongoing effort to soften the impact of the mountain’s inevitable movements.

Intermittent showers have continued to wash over the region, turning the dust to slick mud and keeping the threat of further slides alive in the minds of the engineers. The road between Heren and Chongde has become a zone of heightened awareness, where every raindrop is a potential catalyst for change. It is a landscape that demands a certain humility from those who traverse it, a recognition that we are guests in a territory governed by geological time.

The Daqingshui Tunnel stands as a bridge between the north and the south, but also as a symbol of the resilience required to live in a land defined by its peaks. The steel roof may be dented, and the traffic may be slow, but the connection remains. We patch the holes, we hang the nets, and we continue the journey, knowing that the mountain will always have the final word in this long, winding conversation between the stone and the sea.

The Highway Bureau confirmed that a three-meter rock fell into the Daqingshui Tunnel at the 159.4-km mark of the Suhua Highway early Sunday, damaging the structural roof. While emergency repairs allowed the tunnel to reopen within hours, traffic remains limited to a single lane with alternating directions. Authorities are monitoring the slope around the clock and plan to install a rockfall protection net 50 meters above the tunnel to mitigate risks from ongoing heavy rainfall.
