Three bridges to be build by the Ja­panese Govern­ment

Bhutan Times - - Home - Sangey Ten­zin

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.
