This paper, using hydro code -LS-DYNA, investigates and observes the dynamic response of cemented bridge under the effect of a number of TNT explosives placed around the columns. Damage quantities will be reported accordingly. To ensure the efficacy of the finite-element method, a comparison is made between numerical and experimental results derived from army explosive ordinance America TM5-855-1. The results indicate that no damage whatsoever occur on the deck under the effect of 500 kilogram TNT explosives at one-meter distance from the bridge base while the has base undergone 2 meters of damage along X direction and 3.5 meters along Y direction. Moreover, the area of damage is at the pile as high as 4 meters, and under 1000 kilogram TNT explosives' blast, the length of the base damage is 3 meters at X direction and 6 meters along Y direction.
