To address water shortages around Malaysia's capital Kuala Lumpur, Southeast Asia's longest tunnel, built by a Japanese company, was successfully completed on the 19th, with construction workers enthusiastically celebrating the moment of completion.

It is reported that the project was funded by the Malaysian government using yen loans provided by the Japanese government, and was built jointly by two major Japanese construction companies and local Malaysian firms, taking five years to complete. The 44-kilometer-long "Southeast Asia's longest tunnel" was built to channel water from a neighboring state to solve water shortages in the capital Kuala Lumpur and surrounding areas caused by population growth.

   According to reports, on the 19th, witnessed by the tunnel construction workers, a large excavator broke through the final rock, connecting the tunnel. Many workers hugged each other in enthusiastic celebration. A Malaysian female construction worker said: "This is the best moment of my life. People suffering from water shortages will benefit from this."

   The tunnel runs through mountains at an altitude of more than 1,000 meters and was once affected by unexpected spring water inflows during construction. However, thanks to adequate countermeasures, these difficulties were all resolved. Project manager Takashi Kawada said: "Southeast Asia still needs infrastructure development. We will continue to fully leverage our technical role and do our part for infrastructure development."
