Sydney Harbour Bridge 🌉 Australia 🇦🇺

#australiatrip Every time I pass by the Sydney Harbour Bridge, I can't help but take out my phone to take photos 📸. I feel that the designer of the Harbour Bridge is an amazing person who can make his work a landmark of a city. This shows his design level, ability, foresight, and wisdom. The Harbour Bridge 🌉 is a highway and railway dual-purpose bridge with a mid through open eyebrow single hole double hinge steel beam structure. This world's number one single span steel arch bridge was designed from 1857, started construction in 1924, and was completed and opened to traffic on March 19, 1932, taking more than & years.
