A massive explosion marked the successful demolition of a bridge in eastern China.

The spectacular video was filmed in Ji'an City in Jiangxi Province on July 19.

This demolition signifies the end of an era for the Ganjiang Bridge, which has been a significant part of the city's development.

Spanning 1,057 metres in length and 15.5 metres in width, the Ganjiang Bridge, a box-type arch bridge, was a vital transportation hub since its completion. However, with increasing traffic, particularly heavy trucks, the bridge was long overstressed, leading to severe damage on the west side and key components of the main arch.

Professional assessments highlighted significant safety risks, emphasising the urgent need for its removal and replacement to enhance traffic capacity and navigational standards.

To ensure the demolition went smoothly, Jishui County's government prepared a detailed and precise blasting plan, addressing key aspects such as personnel evacuation, safety measures, traffic control, and emergency responses.

Over 1,000 personnel, including police, urban management teams, emergency responders, and local officials, were deployed to maintain comprehensive security and patrol the area. Following the detonation command, the bridge collapsed in a controlled sequence, and the demolition proceeded safely and orderly.

Post-demolition, Jishui County promptly began cleanup operations to restore navigation and launched the construction of a new Ganjiang Bridge.

The new bridge, designed to be 33.5 metres wide with six lanes, will meet Grade II navigational standards and combine highway and urban bridge specifications.

This new structure is expected to significantly improve traffic conditions and support the development of the Gan-Yue Grand Canal, playing a crucial role in the local economic and social growth.

Construction of the new bridge is slated for completion in March 2027, and it will serve as a critical link to the Gan-Yue Expressway, Jinzhang Avenue, and Jishui High-Speed Rail West Station, offering enhanced safety and convenience for local residents and travellers.

7月19日10时58分，随着一声巨响，江西省吉安市吉水县赣江大桥老桥爆破拆除工程顺利实施，标志着这座见证城市变迁的大桥正式退出历史舞台。

吉水赣江大桥全长1057米，桥梁宽15.5米，桥型为箱形拱桥，自建成以来一直是当地重要的交通枢纽。然而，随着车流量的不断增加，尤其是大型货车的频繁通行，大桥长期处于超负荷运行状态，导致大桥西侧桥台和个别主拱圈主要构件出现严重病害。经过专业检测，该桥被评定为四类桥梁，存在极大的安全隐患，亟需拆除重建以提升通行能力和航道等级。

为确保爆破拆除工作的顺利进行，吉水县委县政府制订了科学严密的大桥爆破拆除工程实施方案。同时，针对人员疏散、安全警戒、交通管制、应急预案等关键环节，项目团队也进行了精细部署，确保每一个环节都万无一失。

爆破当天，吉水县人民政府发布了相关公告，提醒公众注意安全。在警戒区域内，公安干警、城管应急救援人员、乡镇干部等共计1000余人联合行动，对现场进行了全面警戒和巡逻。随着总指挥下达爆破指令，大桥在预设的起爆顺序下依次倒塌，整个爆破过程安全有序。

爆破完成后，吉水县立即组织专业团队进行打捞清理工作，确保尽快恢复通航。同时，新吉水赣江大桥的建设工作也已全面启动。新桥设计桥宽33.5米，双向六车道，通航等级二级，将按一级公路兼顾城市桥梁的标准进行设计。新桥的建设将进一步提高改善通行条件，为赣粤大运河的建设打下坚实的通航基础，对促进吉水县经济社会发展具有重要意义。

据悉，新吉水赣江大桥建设工期为36个月，计划于2027年3月份竣工通车。届时，这座新桥将成为吉水县连接赣粤高速公路、金樟大道及吉水高铁西站的重要通道，为当地居民和过往车辆提供更加便捷、安全的交通环境。
