Abstract
Bridges, especially highway bridges, are a key factor in nations’ development and flourish. Thus, great care should be taken to maintain and inspect their safety and serviceability. An immediate repair will prevent the loss of life and vehicles damage while crossing underpass and overpassing the heavy deteriorated bridges. Reinforced or pre-stressed concrete bridge girders become structurally deficient because of severed reasons including, increasing in the load requirements, corrosion of pre-stressing strands or reinforcement bars and collision of over-height trucks with the bulb of the concrete girders. The purpose of this case study is to evaluate and assess the damages of the highway bridges in Jordan. Since there is no mandatory program in Jordan for inspection of bridges and evaluating their conditions, this paper presents an inspection and assessment of two highway bridges along the desert highway which is the essential nerve connecting Jordan cities, and it also serves as an international road between many middle east countries. These two Bridges have never been investigated or checked since their construction in the late 1980s. The study results showed that the main factor causing the deterioration of these bridges is the collision of the over-height trucks with their elements. Relying on the collected data, solutions and repair methods were introduced to rehabilitate these bridges and assure their structural safety.

Highway bridges are very important structures in modern transportation net, so a great concern should be taken regarding bridges safety and serviceability

Summary
Highway bridges are very important structures in modern transportation net, so a great concern should be taken regarding bridges safety and serviceability. Reference [2] developed a new method that has proven suited for strengthening and stiffening reinforced and pre-stressed concrete bridge girders. Reference [5] performed a detailed evaluation on 12 five-girder T-beam bridges in the southwestern US They concluded that several factors were causing a failure mechanism, including a limited recognition in the original design standard of cyclic loading, high volume of heavy truck traffic, and transverse moments caused by unbalanced wheel loading. This case study can lead to building up a comprehensive Database regarding Bridges status in Jordan, in which the Bridges can be classified into categories with respect to their maintenance priority. This proposition will greatly help in avoiding Bridges accidents
