'''Mangde Chhu''' or '''Tongsa''' river flows in central [[Bhutan]] traversing roughly north–south. The river rises in [[Wangdue Phodrang]] district (or [[dzongkhag]] in [[Dzongkha]]), near [[Gangkhar Puensum]], Bhutan's highest peak at {{convert|7546|m|ft}}. Bhutan's main east–west highway crosses the Mangde Chhu about {{convert|8|km|mi|0}} west of [[Trongsa]]. South of Trongsa, the river drains the eastern slopes of the [[Black Mountains (Bhutan)]], and forms the eastern boundaries of [[Jigme Singye Wangchuck National Park|Black Mountain National Park]] and [[Royal Manas National Park]]. Another highway follows the river south from Trongsa to Shemgang. The highway leaves the river at Tingtinbi, and eventually reaches the Indian border at Gelegphug. South of Tingtinbi, the Mangde is joined by the [[Bumthang River]] from the east, and is known as the Tongasa. Shortly before entering [[India]] in [[Assam]], the [[Manas River]] flows into the river from the east, and the river exits Bhutan near [[Royal Manas National Park|Manas]].

Important towns and areas through which the Trongsa - Gelegphug road passes are Shemgang (Shamgong), Taama, Bataase, and Surey rice fields. The road and bridges were built by the [[Indian Border Roads Organisation]]. Among the number of bridges built across this river, two are noteworthy. They are the [[Bailey bridge|Bailey]] suspension bridges of about {{convert|360|ft|m|disp=flip|adj=on}} span, one near Hathisar and the other at Tama built between 1963 and 1965.
