There were many types of bridges in Sudan made of concrete and/or steel using various types of suspended, steel truss, arch and cable-stayed bridges which were constructed by different methods. The successes in bridge projects will be reached if the project achieved quality, cost saving and completed in optimum time schedule. Therefore, selecting appropriate bridge construction method is essential for the success of bridge construction projects. The Analytical Hierarchy Process (AHP) method has been widely used for solving multi- criteria decision-making problems. The Authors applied Fuzzy AHP, similar to the process suggested by Nangin 2008, to select the most appropriate construction method to be adopted for the Cable-stayed Tuti-Bahri Bridge Project which the Ministry of Infrastructures and Transportation of Khartoum State intends to construct at Khartoum city-center.The results were successfully applied for selection of the most appropriate bridge superstructure construction method among two methods.The hierarchy of the alternatives issuggested based on opinion of twoSudanese expertsthroughquestionnairesto obtain thebasic criteria. Weights, from group of evaluations,areanalyzed using excel spread sheets developed by the Authors. Applying Nang’s approach revealed logical procedure for selection of construction methodthat best suits Tuti- Bahri Bridge. ص  ل  خ  ست  م: إلى تشييد الجسور كبيرة لتحسينلحاجةخرطوم جعل اية الة في ولئية والوديلما ات ا ات من الممرومتر إن وجود عدة كيم والتنميةتصال ال. لخرسانة و في السودان من ا ىناك عدة جسور تم تشييدىا/ ظمة من الجسورفولذ بإستخدام عدة أن أو ال 1 Associate Professor, Faculty of Engineering Sciences - Omdurman Islamic University, Sudan.
