According to the Wikipedia article [0], the bridge is very old and does not meet current clearance standards: > It was designed in the 1920s, and opened in 1940, with a clearance for vehicles of 11 feet 8 inches (3.56 m). This was a standard height at the time it opened. The standard clearance, since 1973, has a minimum height of 14 feet (4.3 m), which is 2 feet 4 inches (0.71 m) higher than the bridge as built. I imagine most trucks are built to be just under 14 feet so that fitting under bridges is not usually an issue. Another thing I’ve noticed watching some of these videos is that most of the accidents are rental trucks. Presumably many of these drivers have never driven a truck in their lives and ignore clearance warnings out of habit.
