[narrator] The bridge

likely saved lives. With the weakness
now identified, it was time for officials
to devise a solution. But a crack this large
doesn't appear overnight. But a crack this large

from an inspection
two years earlier {\an8}showed that the crack

at this stage,

collapsed a week ago when I was going
over the bridge?" So, it freaked me out
