Which bridge is NOT mentioned as a hazard area?

The choice of East bridge as the correct answer hinges on the context of hazard areas typically discussed in navigation and maritime safety. In various navigation publications and charts, specific bridges are marked due to their unique characteristics that could pose risks to vessels, such as vertical clearance, horizontal clearance, or the presence of strong currents around bridge structures.

For instance, Bullocks bridge, Cole bridge, and Pawtucket bridge may have records of navigational hazards or specific guidelines concerning their operational characteristics that affect waterway traffic and safety. These factors include low clearance that could obstruct taller vessels or congested areas that require careful navigation.

In contrast, East bridge does not appear in such discussions or references, indicating that it is not recognized as a significant navigational hazard compared to the others listed. Therefore, it is not highlighted in materials related to safe navigation practices, making it the correct answer to the question about which bridge is not noted as a hazard area.
