Among the impermanent loads on bridge structures, the most frequent one is a vehicular live load and plays akey role in design of the bridge components Most of the developed countries have a comprehensive highway bridgedesign specification while other countries adopt certain renowned design codes but with certain adjustments to meettheir demands. Live Load Models are either modified or calibration factors are proposed for them. In Pakistan twodifferent codes are being followed for highway bridge design i.e. West Pakistan Code of Practice for Highway Bridge(1967) and AASHTO LRFD. Both the codes live load models do not represent the actual load and traffic pattern inPakistan. In this study a WIM data is analyzed, extrapolated to the design period and HL93 live load model is calibratedto represent the true traffic condition of Pakistan.
