Provincial road 316 is a road running along the Da River dike through the territory of Tam Nong and Thanh Thuy districts of Phu Tho province (now communes: Tam Nong, Dao Xa, Thanh Thuy...).
According to the reporter of Lao Dong Newspaper on the morning of September 9, 2026, both sides of provincial road 316 are densely populated, with a fairly large volume of transport vehicles circulating.
On the route, it is easy to record many locations where the road surface has peeled off, cracked, and there are many potholes and craters with water stagnation.

Mr. Tuan Anh - a resident of Tam Nong commune - shared: "The dyke road has not been repaired for many years and is now damaged, dusty in the sun and muddy in the rain. Therefore, it needs to be repaired to ensure the safety of people's travel, especially students.
The project to renovate and repair provincial road 316, section from km0 - km9+950 was approved according to Decision No. 1912/QD-BDA dated June 15, 2026 of Phu Tho Provincial People's Committee.
This is a project belonging to group C, with a total investment of 150 billion VND invested by the Phu Tho Regional Project Management Board.
According to the reporter's investigation, the project investor has just issued a bidding invitation notice for Package No. 07: Construction of works.
Package No. 07 was widely bid through the network, with a value of nearly 135 billion VND from revenue exceeding the provincial budget in 2025 (according to Decision No. 495/QD-UBND dated February 14, 2026 of the Provincial People's Committee) and medium-term public investment capital of the provincial budget for the period 2026 - 2030.

In the near future, after completing the contractor selection work, the winning bidder will deploy the construction of renovation and repair of provincial road 316, nearly 10km long, passing through Tam Nong commune, Dao Xa commune and Thanh Thuy commune.
Regarding the scale of construction investment, based on the current status of the old roadbed and surface, design and repair damaged locations. At the same time, repair and complete the drainage system and traffic safety system on the route.
Regarding design solutions, the route diagram follows the center line of the existing old road, ensuring compliance with the design standards of the road's scale, harmoniously combined with the traffic safety system, limiting site clearance for residential areas on both sides of the road.

The road being renovated and upgraded will have a roadbed width of 9m, a road surface width of 8m, and a sidewalk width of 0.5m on each side. The section from km5+230 - km5+850 through residential areas will have a road surface width of 8m, trenches on each side of 0.25m and curbs on both sides...
Regarding the implementation progress, from the start of construction to the acceptance and completion of the project is 450 days (completed before December 31, 2027).
According to the investor, the project is invested to meet the transportation needs in the area. From there, reduce transportation costs, minimize environmental pollution, improve the efficiency of agricultural/forestry production, trade, services, tourism, contributing to promoting socio-economic development.
