What are the two types of transportable bridges employed by Seabees?

The two types of transportable bridges employed by Seabees are the Bailey Bridge and the Medium Girder Bridge.

The Bailey Bridge is a modular type of bridge that can be quickly assembled and disassembled, making it highly effective for military operations where speed and mobility are crucial. It consists of prefabricated parts that can be transported easily and assembled on-site, enabling Seabees to provide vital infrastructure in a short amount of time.

The Medium Girder Bridge is another transportable bridge designed for heavier loads and longer spans. It is also modular and can be erected rapidly. This bridge type supports military operations as it can accommodate heavier vehicles and equipment, facilitating movement and logistics in combat environments.

Both of these bridge types exemplify the Seabees' capabilities in engineering and infrastructure support, reinforcing their critical role in ensuring mobility for military forces.
