Oddly enough, the old original 7 mile bridge in marathon is holding up much
better than it's replacement.

Although the original span has been rehabilitated several times,
starting with when it was made a roadbed, it may well be "holding up"
much better. There are many, many variables involved. Even the
placement of the new span, in relation to the original alignment might
factor in. Founding soils could be quite different in that amount of
space, the old span might protect the new, etc, etc, etc.

Nothing better at a decent price. They epoxy coat now and that will
help.
Trouble is concrete is fantastic at supporting compression, but any
other
direction and get failures.

What about fiber reinforced concrete? What about composite-fiber type
reinforcement bars for concrete? What about using structural steel
members, embedded for tensile reinforcement?

repeat "Nothing better at a decent price"

All versions of the rebar. I do not see where the fiber reinforced concrete
is code for structural members. You people in Florida do not seem to know
how to build safe buildings. True example. After the last bad hurricane,
one of the towns was leveled, except for a couple of houses that looked like
there had not been a hurricane. Turns out they were Habitat for Humanity
built homes and were built to California earthquake standards. 16" stud
centers, bolted to foundation, hurricane straps on the roof trusses.
Florida did not require bolting, hurricane straps, and most are on 24" stud
centers.

Also, what to HELL are you talking about "I do not see where the fiber
reinforced concrete is code for structural members"? As usual, you
don't have a damned CLUE!!!!!!!

The local "lore" is the concrete from Germany was and is much better?

Not odd at all. The original bridges were shameless copies of Roman
