List of crossings of the Chao Phraya River

The Chao Phraya River in Bangkok

The Chao Phraya River flows through Central Thailand from the confluence of the Ping and Nan Rivers in Nakhon Sawan Province southward to its mouth in Samut Prakan Province, where it drains into the Gulf of Thailand. The river has long served as an important channel of water transport, although it was only after the opening of Rama VI Bridge in 1927 that a permanent land transport structure existed over the river. This page lists permanent crossings of the Chao Phraya, starting from the river mouth and continuing upstream to its source.
