They are amazing! The highest one I've seen -more than 300 metres- is the Millau Viaduct in France, it is an enormous cable-stayed road-bridge.

Very nice exposure, I like to share with you Jain sir, that many wonders have been completed in Bangkok. A crowded chaotic City had been shaped into a superb City. Sir, I have written an article” Bangkok, the Venice of East” but we, the Indians could not make Mumbai up to the mark. Thanks.

Thanks prasadjain for a nice hub. There is need for such bridges as traffic is increasing.

Another wonderful bridge, Si Du River Bridge (Hubei, China) is fast progressing. It would surpass all other bridges because of its height.

Thanks for the hub. My sister drove me on the Penang bridge in 1997 when I returned to Malaysia from Toronto. Had a good time. It was quite interesting as the last time I went to Penang was by ferry. Nostalgia!
