Three bridges to be build by the Japanese Government
Three bridges under the Thimphu – Trashgang highway will be built by the Government of Japan as the prepatory survey for the project is underway. The actual .construction will started by the end of 2015. The bridges include the Chuzomsa zam and Nikachu Zam under Wangdue Dzongkhag and Zalamchu zam under Trongsa Dzongkhag. On the request from Royal Government of Bhutan, Japan International Cooperation Agency (JICA) in consultation with the Government of Japan decided to conduct a Preparatory Survey on the Project, Reconstruction of Three Bridges on Primary National Highway No. 1 (Semtokha – Trashigang Highway). The three bridges will be replaced with higher load carrying capacity and carriageway width of 7.0 metre to enable transportation of heavy electro-mechanical equipment for hydropower projects. The Preparatory Survey Team fielded by JICA arrived Bhutan in late July 2014: the Preparatory Survey is the first step in Japan’s Grant Aid Scheme. The aim of the Preparatory Survey is to collect data and provide a basic document necessary to appraise the Project to the JICA and Government of Japan. During the Survey the team will evaluate the appropriateness of the Project, and agree on its objectives and benefits. The team will then prepares outline design; cost estimates and agree on the activities to be carried out by both the parties concerning the basic concept of the Project. The team is currently carrying out detail geotechnical investigation, topographical and profile survey at the bridge sites. With increase in traffic volume, freight tonnage, and safety of the road users it is critical that existing bridges that have outlived their design life are strengthened to have safer and reliable road transport network that meets the growing demand of transportation. These bridges are currently used with restricted loading capacity and carriageway width. The Minutes of Discussion for the Preparatory Survey on the Project, Reconstruction of Three Bridges on PNH No. 1, was signed between Department of Roads, GNHC and JICA on 6th August 2014.
