1. COMPONENTS OF BRIDGE

2. 1. FOUNDATION The lowest part of the bridge, responsible for transmitting the load of the bridge to the soil. Usually provide deep pile foundations.

3. 2. ABUTMENT Abutment is a vertical structure at the end of a bridge. It supports the bridge deck and connects it to the embankment. Also act as retaining walls, holding back the embankment and providing stability to the entire structure. Subjected to lateral pressures mainly from the embankment. Abutment’s foundation must overcome the problems of differential settlement and excessive movements caused due to Lateral pressure.

4. 3. PIER Pier is a intermediate vertical structure used to support the span. Also transferring the loads to foundation. Most of the cases Piers are designed to resist the vertical load alone, but in seismic areas it is recommended to design the pier for lateral loads also.

5. 4. WING WALL Wing wall is a retaining wall that extends from the abutment. serving to hold back the soil of the bridge approach, prevent erosion, and guide water flow. Essential components for stabilizing the abutment and ensuring the long-term integrity of the bridge structure.

6. 6. DECK SLAB It is the top, structural surface of a bridge. transfer the load of vehicles and pedestrian traffic. It is typically a thick, flat slab made of reinforced concrete that rests on girder beam.

7. 7. BEARINGS Bridge bearings play a crucial role in ensuring the structural integrity and longevity of bridges. By allowing for controlled movement and rotation, bearings reduce stresses and prevent damage to the bridge structure. Mainly set between the bridge and pier.

8. 8. GIRDER BEAM Girder beam is the Part of superstructure. Providing primary structural support to the bridge deck. Girder beams resist bending and shear forces by utilizing the combined strength of their components, such as the flanges and web.

9. 9. APPROACH ROAD It is the part of a road that leads to a bridge, forming a transition zone between the regular roadway and the bridge deck. It also prevent issues like settlement
