Those "low clearance" signs are there for a reason...

Someone could make a video like that in Boston. Best place would be at
the Charlesgate exit off of Storrow Drive; best time would be "moving
day" at the beginning of the fall college semester. An over-height
truck crash there is virtually guaranteed on that day each and every
year.

The steel I-beam to protect the bridge in the video itself is a good
idea that I've seen used at other bridges and tunnels. In
Massachusetts though, it is preferable for the vehicle to inflict as
much damage as possible on the structure, which may or may not ever be
repaired.

If it happens more than once a year, they should put up a thing about
50m before the bridge. This thing would drape a few chains about 50mm
(2") below the bridge height.

There are actually rubber flaps, chains, and other "draped" physical
warning devices, in addition to some dysfunctional warning alarms here
and there, but over height vehicles either don't notice or seem to
think they don't apply to them. I think it really needs something on
the order of a steel I-beam to actually get their attention.
