Site Survey and Design: Before construction begins, a detailed survey of the site is conducted to assess terrain, soil conditions, and hydrological factors.  This information is crucial for designing a bridge that can withstand local environmental stresses.  Engineers then develop plans that outline the bridge's structure, dimensions, and materials.

Foundation Construction: The foundation is the most critical part of a bridge, as it supports the entire structure.  Depending on the site conditions, different foundation types may be used, such as pile foundations or shallow foundations.

Substructure and Superstructure Construction: The substructure includes components like piers and abutments, which transfer loads from the superstructure to the foundation.  The superstructure, which includes the deck and beams, is then constructed.  Modern bridge construction often employs prefabricated components to improve efficiency and quality.

Quality Control and Safety Measures: Throughout the construction process, rigorous quality control measures are implemented to ensure that the bridge meets safety and durability standards.  Safety protocols are also strictly followed to protect workers and the public.
