A steady seepage of salt water into the structure, built in the 1960s,

But no, the cheaper but potentially very damaging rock salt was used,
and this is what has caused the problems with the pre-stressing cables
within the concrete structure.

Presumably this isn't the only structure of this type on the road network
though?

Are many more due to be found before long?
