As things get harder,
it becomes more brittle
00:00:03.367 --> 00:00:05.245
and is more prone
to snap and crack.
00:00:07.997 --> 00:00:10.001
[narrator] Despite showing
signs of serious fatigue,
00:00:10.127 --> 00:00:13.805
closing the crossing
altogether wasn't an option
00:00:13.088 --> 00:00:18.725
This bridge is absolutely
critical to the essential
economic activity
00:00:18.767 --> 00:00:20.685
of New Zealand as a whole.
00:00:23.014 --> 00:00:27.565
[narrator] The solution was
as radical as
the original design.
00:00:27.567 --> 00:00:31.205
The only way
to protect the bridge
and the New Zealand economy
00:00:31.247 --> 00:00:37.525
was by removing
and rewelding the failed
connections one by one.
00:00:37.527 --> 00:00:40.925
But removing too many at onc
threatened the structure
00:00:41.000 --> 00:00:43.885
falling under its own weight
00:00:43.887 --> 00:00:46.245
They had to be individually
taken off about 2000
00:00:46.247 --> 00:00:50.026
of these splices,
all in all that were replaced
and upgraded.
