Song Wat Road (Thai: ถนนทรงวาด,, in Thai pronounced as /tʰā.nǒn sōŋ wâːt/) is a historic road in the area of Bangkok's Samphanthawong district. It has its origins by separating from Chak Phet road near Chakkrawat police station and foot of Phra Pok Klao bridge on the borderline of Chakkrawat sub-district, Samphanthwong district and Wang Burapha Phirom sub-district, Phra Nakhon district, then cuts across Ratchawong road in the area near Ratchawong pier, as far as ending at Khao Lam cycle, where it combines Khao Lam and Charoen Krung roads in Talat Noi sub-district in the area known as Sieng Kong (เซียงกง) or officially Soi Wanit 2 (ซอยวานิช 2). The distance is 1,196 m (about 0.6 mi) alongside Chao Phraya river almost all the length.
The name "Song Wat" translates to "drawing by the king". It was built by King Chulalongkorn (Rama V) in 1892 after the great fire in Sampheng area. The Siamese government wanted to expand the roads and public utilities to a wider area, such as Yaowarat, etc. For Song Wat, it was from the King Chulalongkorn who wrote the line with a pencil on the map by himself. The construction was divided into two phases. The first phase starting from Chak Phet road to ends at Trok Rong Krata (now's Yaowaphanit road) in 1892, the second phase began in 1907 from Trok Rong Krata to ends at Charoen Krung road like today.
Song Wat road then developed to function as main access to water transport in the area along the road, there are a number of minor roads and alleyways bridging with the port which served all the steamships communication between Chon Buri province, Ban Don (Surat Thani province), and Bangkok, as well as the barges running between the seaside towns and the capital. Song Wat area therefore was the main transport region of seafood, vegetables, plants and herbs the row-shophouses along both sides of the road are mostly the wholesale companies and shops doing businesses related to the vessel-transported commodities. The road also the origin of the business of many Thai Chinese millionaire families, such as Chearavanont, the owner of CP Group, Chatikavanij, Sirivadhanabhakdi, or Kanchanachoosak, etc.
