Currently, the Ethiopian government has given special attention for road construction sector and is to invest billions of dollars. Parallel to road construction, there is also a demand of construction of bridges as most of the existing ones are getting older as they are constructed, during colonization by Italians. Construction of such bridges naturally occupy longer construction time where the time required may be farther exacerbated due to shortage of budget beside having bad construction management practice which is observed in many construction undertakings. Associated with this, the normal day to day traffic flow is affected and causes discomforts to the road users. This problem is serious especially in towns where there is high traffic volume and provision of detours is not simple. Thus, as alternate, steel-concrete composite bridge which obviously shortens the construction time and alleviates the problems with other added advantages is thought in this study. Therefore, in this thesis attempt is being made to compare the usage of locally produced steel profile in steel-concrete composite bridges with the conventional reinforced concrete deck girder bridges cost wise, beside evaluating other merits of such application. In the thesis work, relevant literatures are reviewed, assessment of availability of local steel profiles for such application has been made to local private and governmental companies that are engaged in manufacturing, supplying and installing of such steel profiles for different engineering purposes. Kality Metal Products Factory, Mesfin Industrial Engineering PLC and Maru Metal Industry are among some whose local products are considered. Accordingly, it is observed that there is local capacity and experience of manufacturing I-section profiles byenComposite; BridgesThesis
