一 |     　　武汉8月24日电(葛利龙 余哲)随着最后一根猫道承重索精准下放至桥面，由湖北交投投资、中交二航局承建的湖北燕矶长江大桥猫道拆除工程23日全部完成，标志着这座世界最大跨径四主缆悬索桥全面进入上部结构施工收尾阶段，正全力冲刺年底建成通车目标。图为猫道全部拆除完成的燕矶长江大桥。　(无人机照片) 葛利龙 摄　　燕矶长江大桥横跨鄂州与黄冈两地，采用一跨过江设计，主跨达1860米，项目全长约26公里。上层为六车道高速公路，设计时速100公里；下层为四车道城市快速路，设计时速80公里。作为串接鄂州和黄冈沿江发展轴、对接湖北国际物流核心枢纽机场的重大交通工程，大桥建成后将打通沿线交通瓶颈，强化两市经济联系，极大完善区域“公、铁、水、空”综合交通运输体系。　　猫道是悬索桥施工中不可或缺的临时高空作业通道，平行布设于主缆下方，主缆索股牵引、紧缆压实、索夹与吊索安装、主缆防腐涂装等全部关键工序均依托猫道展开。燕矶长江大桥采用独特的四主缆设计，内外主缆下方各设一条猫道，将南北两岸主塔相连。单条猫道宽3.45米，长约3公里，四条猫道总长达12公里，是目前世界上最长的猫道。    Shantanu Maheshwari is currently in South Korea. The actor has recently interacted with the K-Pop girl group X:IN and achieved an incredible feat. For those unaware, his film, Love in Vietnam has won two awards at the Seoul Global Movie Awards 2025.          Besides the film showcasing in India, it was earlier this year screened at the DaNang Asian Film Festival in Vietnam. Interestingly, the makers have arranged a special screening for the Korean audience of the film. Shantanu further shared his excitement on winning big at the awards show. He said, “It was such an unbelievable moment to witness Love in Vietnam picking up not just one, but two awards at the Seoul Global Movie Awards. This is a huge milestone! As it's the very first time an Indian film has won two awards there. That made our victory feel even more special, and honestly, it was surreal.”He spoke about meeting other stars and being recognised on a global scale. He said, “Meeting so many incredible Korean stars and veteran actors in the audience was a dream come true. And just stepping onto that stage, getting recognized internationally for our film, felt like a beautiful dream I didn’t want to wake up from. I’m truly grateful to see the film being accepted so well on such respected International platforms.”"It was so touching to see the Korean audience’s enthusiasm. They were genuinely excited about watching the film on its releases there. I want to thank Rahhat sir for believing in me and giving me the opportunity to be a part of this film. I missed the rest of our team, especially those who couldn’t be there. This entire experience in Seoul has been unforgettable,” concluded Shantanu.          Alongside Shantanu, the movie also stars Avneet Kaur and Kha Ngan. It was released in India on September 12, 2025.Also Read: Shantanu Maheshwari and Avneet Kaur On Love In Vietnam | Filmfare Exclusive。
