Which type of pier is commonly used with wide super structures?

The choice of a cantilever or hammerhead pier is particularly suitable for wide superstructures due to its design characteristics and structural capabilities. These types of piers are robust and provide substantial lateral stability, which is essential when supporting broader spans typical of wide superstructures. The hammerhead design, with its wider top section, is specifically effective at distributing loads across a larger area and accommodating increased forces from heavy traffic or lateral movements.

In contrast, column or open bent types generally support narrower spans and might not offer the same level of structural integrity required for wider applications. Pile bents are typically used in scenarios where high vertical loads are predominant, and while they can support superstructures, they might not provide the necessary resistance to lateral forces as effectively as hammerhead piers. Drilled piers, while useful for deep foundations and bearing capacity, are not primarily designed for accommodating the wide span requirements of the superstructure.

Hence, the cantilever or hammerhead pier emerges as the ideal choice for wide superstructures, providing the necessary support and stability under various load conditions.
