Bridges, especially highway bridges, are a key factor in nationsâ?? development\nand flourish. Thus, great care should be taken to maintain and inspect their\nsafety and serviceability. An immediate repair will prevent the loss of life and\nvehicles damage while crossing underpass and over passing the heavy deteriorated\nbridges. Reinforced or pre-stressed concrete bridge girders become\nstructurally deficient because of severed reasons including, increasing in the\nload requirements, corrosion of pre-stressing strands or reinforcement bars\nand collision of over-height trucks with the bulb of the concrete girders. The\npurpose of this case study is to evaluate and assess the damages of the highway\nbridges in Jordan. Since there is no mandatory program in Jordan for\ninspection of bridges and evaluating their conditions, this paper presents an\ninspection and assessment of two highway bridges along the desert highway\nwhich is the essential nerve connecting Jordan cities, and it also serves as an\ninternational road between many middle east countries. These two Bridges\nhave never been investigated or checked since their construction in the late\n1980s. The study results showed that the main factor causing the deterioration\nof these bridges is the collision of the over-height trucks with their elements.\nRelying on the collected data, solutions and repair methods were introduced\nto rehabilitate these bridges and assure their structural safety.
