Where can anchorage zones typically be found in a bridge?

Anchorage zones are areas where forces from cables, tendons, or other elements are transferred into the structure, and they play a crucial role in maintaining the stability and integrity of the bridge. In the context of bridges, especially those that utilize precast elements, anchorage zones are specifically associated with the locations where precast deck tie rods are installed.

Precast deck tie rods are often used to connect the precast deck panels to each other and to the supporting structure. The anchorage zone at these tie rods is critical because it is where the tension forces from the bridge deck are transferred into the underlying structure and helps ensure that the deck remains securely in place, especially under loads and dynamic conditions.

While areas like the main trusses, bridge deck, and abutments play significant roles in the overall structure of a bridge, they do not serve the same specific function of anchoring the precast components in the same manner as anchorage zones at the precast deck tie rods, making this choice the most appropriate answer for the location of anchorage zones in a bridge.
