What do you need to know when passing under a river bridge?

Understanding the clearance height under a river bridge is essential for safe navigation when passing underneath. This measurement helps determine whether a boat can safely pass without risk of grounding or damaging the structure. Many bridges have specific clearance heights that can vary based on factors like water levels. Knowing this height ensures that operators can make informed decisions regarding their vessel’s safe passage, especially considering different water conditions that may affect actual clearance.

While knowing the boat speed limit, the width of the bridge, and the depth of the water are also important aspects of navigation, they are not as critical as clearance height when it comes to preventing collisions or accidents with the structure above. The speed limit pertains more to safety and control during transit, the width relates to maneuverability, and depth is a factor in grounding risk; however, ensuring that the vessel can fit under the bridge is paramount.
