    The Commonwealth of Puerto Rico has over 2200 in-service bridges as part of their inventory and more than 50% of these bridges were constructed over 30 years ago. Seismic design requirements are updated frequently due to research and innovations, and bridges are essential structures in the transportation systems that must be designed to withstand seismic events. Because of this, the seismic analysis of bridges designed and constructed at a time when seismic design provisions were insufficient according to current standards should be considered as a required step to determine their performance and capacity to withstand lateral loads during seismic events. In this study, a detailed seismic analysis was performed on Bridge No. 2001 in Highway PR-22 over Bayamón River & Rio Hondo Channel in Bayamón, Puerto Rico. The seismic analysis of this bridge was completed following the Component Capacity/Component Demand Ratio (C/D Ratio) methodology of the FHWA publication entitled Seismic Retrofitting Manual for Highway Bridges. C/D ratios were determined for various bridge components and it was found that some of these bridge components are in need of possible retrofitting. Bridge components in need of retrofitting include: hinge connections, shear keys, piers, pile caps, piled foundations and soils. Retrofitting measures for the strengthening of these bridge components were presented, as part of this study, to improve their seismic performance as well as the seismic performance of the bridge.
