[narrator] Taking a full yea By 1986, the second bridge fix was complete, but it was more of a band ai than a permanent solution. Every repair adds more weight,

to overload the bridge, essentially making its problems worse. The latest fix alone involves

[narrator] Taking a full yea
By 1986,
00:00:04.012 --> 00:00:07.078
the second bridge fix
was complete,
00:00:07.008 --> 00:00:10.998
but it was more of a band ai
than a permanent solution.
00:00:11.000 --> 00:00:14.398
Every repair adds more weight,
but add too much
00:00:14.004 --> 00:00:17.398
and the fixes would start
to overload the bridge,
00:00:17.004 --> 00:00:20.478
essentially making
its problems worse.
00:00:20.048 --> 00:00:25.238
The latest fix alone involves
75 miles of new welds
00:00:25.024 --> 00:00:30.118
and 200,000 new bolts
adding unanticipated weight
00:00:30.002 --> 00:00:33.997
to a structure that's now
five decades old.
