Official report on bridge collapse

On Monday evening, the People's Committee of Phú Thọ Province reported on the collapse of Phong Châu Bridge.

At approximately 10:02am on Monday, Phong Châu Bridge, which connects Tam Nông and Lâm Thao districts in Phú Thọ Province, collapsed, as floodwaters swept away support pillar T7 and two main spans, per the report.

Vice Chairman of the National Assembly Trần Quang Phương visits the victims of the Phong Châu Bridge collapse who are being treated at Tam Nông District Medical Centre, Phú Thọ province.

Preliminary reports indicated that at the time of the incident, ten vehicles were on the bridge, including one truck, two tractor-trailers, six motorcycles, and one electric bicycle.

Eight people are missing, and three individuals have been rescued and hospitalised.

Immediately after the collapse, leaders from the People's Committee of Phú Thọ Province arrived at the scene and initiated emergency measures to rescue victims.

Due to the high and swift floodwaters, the search and rescue efforts have faced significant challenges, making it difficult to accurately determine the number of vehicles and missing persons.

Phú Thọ is urgently conducting a thorough review to accurately ascertain the number of people and vehicles involved in the incident.

The province is coordinating with Military Region 2, Hà Nội, and Vĩnh Phúc Province to inspect downstream river routes for continued search efforts.

Additionally, preparations are being made to search and rescue in the area around the bridge once conditions allow.

The province is also implementing remote traffic diversion plans, guiding vehicles to alternate routes such as Ngọc Tháp Bridge, Nội Bài-Lào Cai Expressway, and Đồng Quang Bridge. A temporary ferry bridge is being installed to facilitate transportation for the public.

Moreover, Phú Thọ Province has stationed guards, installed warning signs, and set up barriers to alert and prevent people and vehicles from entering the hazardous area.

Phú Thọ has requested the Ministry of National Defence and Military Region 2 to consider installing a temporary pontoon bridge to ensure continued transportation for residents.

The province has also requested that the Prime Minister direct the Ministry of Transport to invest in the construction of a new bridge to replace the old Phong Châu Bridge. — VNS
