The
golden gate bridge, an american icon
San Francisco’s famous orange bridge
is 80 years old this year. But the engineers and workers who build it
had a difficult job.
The bridge’s official colour,
“international orange”, has made it one of the famous bridges in
the world. But at first, people weren’t convinced. The orange
chosen is the result of a chemical mixture.
It’s the longest suspension bridge
and is divided into six lines for traffic and was built with 75.000
tons of steel and 120.000 rivets were used. Designing it was
complicated because it is in a bay that has frequent earthquakes and
had to resist violent winds.
I’ve visited this bridge and it’s
my favourite one because it has a great design and the colour is very
impressive when you see it for the first time. It’s very long and
we took a good walk to cross it, but it’s so nice because the
sights and the landscape are so beautiful.
