I have i friend who is a laborer on a new bridge being built in the area. He said said they told him that they build bridges with holes covered by
removeable plates in strategic places so if their is a war on our soil we can put explosives in these holes and take down the bridge. If this is true
it gives terrorists an advantage to take down bridges
I am not sure about war and blowing bridges, but my grandfather built bridges back in the 50-60's and they placed holes in certain areas to use for
explosives in case they ever need to demolish the bridge.
Not sure if this is accurate or not, but it is what gramps told me.
They do the same thing with large buildings in Urban Areas for future demolitions, I think it has more to do with City Planning than it does war or
terrorism, but you are right though, it certainly would provide an extra opportunity.
I know for an absolute fact that some interstates have had that done to them over the years. I don't want to name roads or overpasses but I am sure
that anyone interested can find out easily. I do not know what these holes look like, I just know they are there.
geez...this is a worry....it makes sense from a building/demolition point of view but if this civil engineering ifo fell into the wrong hands, one can
only imagine!!!
Well the particular roads that I am intimately familar with that have these features, were both designed and ? built ? by the Army COE. I do not know
how the "civil engineers" view this idea.
I have no idea if this is related or not:
Last summer they tore up and replaced a roughly 5 mile stretch of road near here. When they put the new road surface down they installed these metal
plates in the center of the road spaced about 1/8 mile apart. Each plate measures about 5" x 5" there are numbers on each one, the surface of the
plate is even with the road surface. Nothing that makes sense of why they are there though.
