Build a bridge by extending your hand: Ken Poirot

1. On March 19, 1932, this iconic bridge was opened by a stranger on a horse. It is one of the most easily identifiable bridges in the world thanks to its four huge granite pylons, which actually play no part in supporting the bridge. Every year, this is probably the first monument you’d see welcoming the New Year. Which bridge is this known by its location?

2. In 1848, for a bridge under construction, engineers needed to secure a line across an 800-ft.-wide chasm. They conducted a kite-flying competition and one local boy managed to fly a kite across and got paid 5$. This eventually became the very first railway suspension bridge connecting the U.S. and Canada. What natural wonder can one see as they cross the bridge?

3. The Øresund Bridge between Denmark and Sweden is the longest in Europe which has both roadway and railway combined in a single structure. The characteristic feature of this bridge was to avoid interference with air traffic from a nearby airport and provide a clear channel for ships. What is this interesting feature that looks amazing in pictures?

4. The Fairy Bridge is a 400-ft.-wide natural bridge carved in limestone by river Buliu in Guangxi province, China. Till 2009, this wonder was not known outside the local area. Jay Wilbur discovered it while sitting at home, and intrigued by what he saw, did some calculations and realised he was looking at the largest natural bridge in the world. What did he use to discover this bridge?

5. This iconic bridge was initially painted with a sealant that was bright orange, and was meant to be painted yellow later. This colour worked better in fog and so was kept as such. The iconic silhouette of the bridge became the logo of a global IT company named after the city in which the bridge is located. Which bridge is this?

6. The Magdeburg Bridge spans river Elbe and was opened in 2003. At 918 metres in length, it is the world’s longest of its kind. What is unique about this bridge is that one cannot drive over it, as there is no road. What does this bridge carry over the river?

7. Engineers built a bridge between Germany and Switzerland across the Rhine from either side, but when they met in the middle they discovered an embarrassing error. The heights of the bridge parts differed by 54 cm. This was due to the Germans basing something on the North Sea, and the Swiss basing it on the Mediterranean Sea. What value is this, which unfortunately is not constant everywhere?
