What joint type allows for a range of movement from 4 to 24 inches?

The assembly joint without seal - finger plate type is specifically designed to accommodate significant movements between bridge sections, making it suitable for ranges of movement from 4 to 24 inches. This type of joint utilizes a finger plate configuration that can interlock between two bridge elements, allowing for horizontal and vertical displacement. The lack of a seal means that while it provides flexibility, it may also allow water and debris to penetrate the joint, which is a consideration in bridge maintenance and durability.

In contrast, other joint types may not provide the specific movement capacity or functionality required for such a wide range. The assembly joint with seal, for example, is generally used for joints that require sealing to prevent water and debris infiltration and typically does not accommodate the same degree of movement. Open expansion joints allow for some movement but tend to have limitations on the amount they can effectively handle. Cellular joint seals are more focused on maintaining seal integrity rather than allowing broad movement ranges. Thus, the assembly joint without seal - finger plate is the appropriate option for handling larger movement ranges effectively.
