CRACKS IN HSUEHSHAN TUNNEL WORRY DRIVERS|雪隧內部多處裂縫 民眾憂影響安全

The Hsuehshan Tunnel has been in operation for nearly a decade. Lately, some people have seen cracks in the tunnels and are concerned about safety. The National Freeway Bureau said in response that cracks are normal and people do not need to be worried. The Hsuehshan Tunnel is always congested on holidays. Recently, cracks have been observed in the tunnel. Some of them are over 2 meters long. People are concerned that these cracks may cause safety problems in case of earthquakes, or water may leak through the walls. ==PASSENGER== I'm worried that cracks may get bigger and cause the tunnel to collapse. It may also be dangerous if there are earthquakes. ==PASSENGER== Water may leak through the walls, and that would be dangerous for drivers. Cracks have also been observed at the Pengshan Tunnel. According to the president of the Taipei Professional Civil Engineers Association, cracks are normal due to temperature variations, but water may leak through if the cracks are too wide. ==HONG CHI-DER, President, Taipei Professional civil Engineers Association== Crack of 0.3 or 0.4 mm wide are normal. Heavy external force can also make the cracks worse. When walls are cracked it is possible for water to seep through. ==LIN SYH-JONG, Chief, National Freeway Bureau Tou-Cheng Section== Inspections are conducted twice a year. We also use equipment to inspect the inside of the tunnel monthly. The pilot tunnel is checked bi-weekly, and we have crew members checking the tunnel every day, so we are certain that there're no safety issues. The National Freeway Bureau said inspections are conducted twice a year, and cracks over 0.5 mm wide will be mended. Inspections are also conducted after earthquakes, so there's no need for people to be concerned.
