During this last cruise we did ( Recap at; https://youtu.be/BYZcE2gDuP8 ) we had to go under a batch of bridges! Each time was scary. I would look them up each day before we started. One day, we got to the 2ed bridge of the day, and they were working on it. AND for safety the workers hung a safety net under it. Could NOT tell the actual clearance!!!!!
We made it, but sure did sweat a bit.
