Bhutan Bridge Construction

Bhutan has a distinctive bridge building heritage spanning centuries, from the iron chain suspension bridges constructed by the 15th-century polymath Thangtong Gyalpo to traditional wooden cantilever bridges known as bazams. This is a list of bridges and viaducts in Bhutan, including those for pedestrians and vehicular traffic. Cantilever beams were developed in order to cross increasingly wide streams or rivers, where simple wooden beams had a limited range of about 10 meters. The surviving Tamchog Chakzam bridge near Paro preserves original. The Construction Division,on behalf of Project Dantak is inviting eligible bidders to provide consultancy services for a proposed 266-meter iconic bridge at km 1. 275 on the Damchu–Haa Link Road under 60 RCC/19 BRTF in Bhutan. The scope of work includes: Tender Documnets can be downloaded below:.
