In Tam Nong district, after Phong Chau bridge collapsed, two other large bridges, Trung Ha bridge connecting Tam Nong with Ba Vi district (Hanoi) and Tu My bridge connecting Tam Nong with Cam Khe district (Phu Tho), limited vehicles due to damage, making it difficult for people to travel, especially for trucks carrying goods.
However, there is a large bridge that has just been put into use not long ago, which is helping to solve the traffic problem for Tam Nong district. That is the Song Bua bridge across the river of the same name, replacing Tu My bridge connecting Tam Nong district with Cam Khe district.
Song Bua Bridge is the only river-crossing bridge on the inter-regional traffic route connecting Ho Chi Minh Road with National Highway 70B, National Highway 32C from Phu Tho province to Yen Bai province - the project route has a total investment of 2,120 billion VND passing through 3 districts of Phu Tho province.
Regarding location, Song Bua bridge is located on Km4+323 of the inter-regional road, in Quang Huc commune and Lam Son commune, Tam Nong district, about 3.5km from Tu My bridge downstream of Bua river (parallel to Tu My bridge).
According to the reporter of Lao Dong Newspaper in mid-October, many vehicles traveling in the direction of Tam Nong - Cam Khe and vice versa passed through Song Bua bridge.
Mr. Bui Van Quang - a truck driver living in Si Hen area, Dong Luong commune (near the bridge) - shared: "I transport goods every day over this bridge, the new bridge is very sturdy and safe. At this time, Tu My bridge is banning cars, so Song Bua bridge has more traffic than before".
Speaking to Lao Dong Newspaper reporters on October 18, Mr. Do The Nam - Director of the Management Board of Investment Projects for Construction of Traffic, Industrial and Civil Works of Phu Tho Province (representing the Investor managing the inter-regional road project) - said that Song Bua Bridge at Km4+323 of the inter-regional road has been completed and put into use since October 2023.
According to Mr. Nam, the project is designed as a simple 5-span girder bridge (according to the diagram 39.1+3x40+39.1m), with a total length of more than 204m (from the end of the abutment to the end of the abutment). The span structure is a Super T girder made of 50MPa prestressed reinforced concrete, with a girder length of more than 38m...
"However, for vehicles traveling from Tam Nong district to Cam Khe district, when passing Song Bua bridge to the first intersection (the intersection in Si Hen area, Dong Luong commune), they will not be able to go straight on the inter-regional road, the reason is because the next section of road has not been handed over and put into use" - Mr. Nam noted.
