The massive urbanization and vehicular traffic have called for the evolution of intricate transportation infrastructure systems, e.g., double-stage flyovers. The multi-level flyovers offer efficient traffic segregation and enhanced mobility in high-density urban areas where horizontal area is scarce. This study addresses the structural design and analysis of a double- stage flyover using SAP2000, a robust finite element program extensively utilized in civil engineering.The research includes modeling of a two-level flyover structure, comprising reinforced concrete super structures with common and independent substructure elements. The analysis takes into consideration a broad variety of load conditions such as dead loads, live loads (IRC Class AA and 70R), seismic loads (according to IS 1893:2016), wind loads, thermal effects, and vehicular impact loads. Suitable combinations of loads are imposed according to relevant IRC and IS code requirements so as to obtain a safe and serviceable design.Core design issues of differential deflection between stages, mechanisms for load transfer, vertical clearance specifications, and foundation-pier interaction are resolved by the use of sophisticated modeling methods. Response Spectrum Analysis is used to analyze the dynamic characteristics of the structure under seismic excitation, and staged construction analysis is taken into account to capture realistic construction sequences.Results show the structural efficiency and reliability of the designed double-stage flyover under different critical load cases. The research concludes that SAP2000 is a valid means of analyzing and optimizing complicated multi-level flyover systems, providing useful information to engineers and planners of urban infrastructure. The research is part of the increasing literature focused on addressing the problem of urban traffic congestion by innovative structural design
