That is but one problem.

Why not? They were originally designed for trucks carrying tanks.

Now where on earth do you get THAT idea from???

-------------------------

One of the many purposes and reasons for Eisenhower's Interstate
Highway project which started in 1956, was to provide a means for
efficient movements of military assets, the requirements of which
contributed to the highway design. Another was for civil defense and
mass evacuations of areas hit by natural disasters. It's the reason
the design consists of lanes separated by a barrier. In the event of
an emergency, traffic can travel in the same direction, using both
sides of the highway.

But LONG after his death, more and more interstate highways were built.
When the built these in cities, many bridges got re-purposed as
interstate bridges and weren't intended nor designed for that kind of
traffic.
