The Tanalung Chu is a picturesque 105m span cantilever bridge located on the important Damchu-Chukha Road in Bhutan above a 120m deep gorge. It will reduce the travel time between Phuntsholing-Thimpu by one hour and reduce journey by around 19.5 Km of steep uphill driving.
The bridge features two cantilever arms (integral with the abutments) which are connected at the center using a needle girder. The needle girder allows for the expansion/contraction of the two cantilever arms due to temperature while keeping the two decks connected for traffic movement. The deck width is 12.0m with footpaths on both side and can cater to two lanes of traffic.
