It may also be worth mentioning that there's another meaning of
"clearance" when referring to vehicles: that of the free space beneath a
vehicle (ground clearance).  So it would seem that "clearance" always
refers to "free space below" -- meaning that it's the bridge's clearance
that is marked.  This does not contradict that it is also the loading
gauge of the vehicles passing underneath it...
