One of the masterpieces of modern architecture, the fantastic Hangzhou Bay Bridge has been opened to the public since May 2008.
The Bridge is an S-shaped stayed-cable bridge with six lanes in both directions and is linking Ningbo's Cixi county in the south to Jiaxing in the north. It shortens the highway travel distance between Ningbo and Shanghai by 120 kilometers, and reduces the driving time from 4 to 2.5 hours.
It is the longest sea-crossing bridge in the world - 36 kilometers (22 miles) long. This fantastic bridge crossing the Hangzhou Bay is expected to have a 100-year lifespan, and has a price tag of 11.8 billion yuan (US$1.70 billion).
The toll fee is 80 yuan per vehicle. As the bridge has six lanes in both directions, you can be quite sure that you will have a smooth ride.
The speed limit is 100 kilometers / 62 miles.
The first preparations for planning the bridge started a decade ago close to 600 experts spent nine years on designing the Hangzhou Bay Bridge. Chief Commander of the Bridge Project is Mr Wang Yong. The bridge was linked in 2007 and an opening ceremony was held on 26th June. But the Bridge was first open to the public, almost one year later, after a series of tests and evaluations.
