Bridge reinforcement is a process used to strengthen existing bridges to ensure they can safely support increased loads and resist environmental factors. This can involve adding materials like steel or concrete to critical areas, enhancing the bridge's overall stability and durability. Engineers assess the bridge's current condition and determine the necessary reinforcements. Techniques may include installing additional beams, using carbon fiber wraps, or adding tension cables. These improvements help extend the lifespan of the bridge and maintain safety for vehicles and pedestrians, ensuring it meets modern engineering standards.
