New Nang Khlao Bridge
Due to development of the neaby residential area the Nang Khlao Bridge over Chao-Phraya River in Bangkok could no longer support the increased traffic volume.
Department of Highways (DOH) initiated the construction of a new bridge to accommodate the future traffic and connecting the East and West Ring Road.
In the project we delivered detailed designs of contructions, spesifications and cost estimates.
The New Nangklao Bridge is a cast-in-place prestressed concrete bridge constructed by the balanced cantilever method. The main span length is 229 m with side spans of 130 m. The width of the bridge is 26.80 m with 6 traffic lanes. The bridge is founded on bored piles through soft layers to 50-60 m depth.
It continues over the Sanambin Nam intersection. Total length of the bridge is 1,685 m. Improvement of connecting roads to harmonize with the New Nangkhlao Bridge makes the total length of the project 2.5 km.
Overall budget of the construction work is approximately 1,400 million baht.
