There are four main types of bridge demolition:
1. Implosion Demolition: A controlled explosion is used to bring down the bridge. This is a popular method that allows for a quick and efficient demolition.
2. High Reach Demolition: Excavators and cranes are used to dismantle the bridge from the top down. This method is typically used for smaller bridges or bridges in urban areas where implosion demolition is not feasible.
3. Hydraulic Demolition: A hydraulic breaker is used to break up the bridge into smaller pieces. This method is often used for concrete bridges.
4. Mechanical Demolition: Heavy machinery such as excavators, bulldozers, and jackhammers are used to demolish the bridge. This is a slower method, but it allows for more precise control and can be used for bridges that require careful dismantling.
