What does the term 'monolithic' refer to in bridge deck construction?

The term 'monolithic' in the context of bridge deck construction refers to a member that is cast as one unit without seams. This construction method creates a single, solid structure, which enhances the strength and integrity of the bridge deck. Monolithic construction minimizes the risk of water infiltration and reduces maintenance needs since there are no joints or seams that could allow for wear or corrosion over time. This design leads to improved durability and reliability of the bridge, as it can better withstand various stresses and environmental factors without the vulnerabilities that joints introduce.
