The Auckland Harbour Bridge is 50 years old today. Sadly there weren't fireworks (and why not?) or a mass walk over the bridge like Sydney did for its bridge's 75th; it would have cost far too much. But fireworks were surely doable.
Happy birthday, Bridge! I have always loved you. I still remember doing a school Morning Talk on you when I was about 8; my love of bridges and engineering feats started early.
