Suzhou has a 9-kilometer (5.6-mile) stretch of open water across Yangcheng Lake. It was finished in 2010 and debuted in 2011. Construction spanned four years and cost roughly $8.5 billion, employing 10,000 workers. It is now China's second longest cable-stayed bridge after the Zhongtian Gate Bridge in Wuhan.
The world's first cable-stayed bridge was built over the Menai Strait between Britain and Ireland in 1826. The Suzhou Grand Bridge is also thought to be the first large scale cable-stayed bridge built in Asia. It remains one of only two cable-stayed bridges in China (along with the Dali Bai National Park Cable-Stayed Bridge).
The total length of the bridge is about 14 kilometers (9 miles), with a main span of 6.5 kilometers (4 miles). It carries four major highways across the lake. There are three interchanges along the route where vehicles can merge into single lanes or join other traffic streams. A fourth interchange serves as a partial toll plaza where drivers must pay an entrance fee before crossing the bridge.
The road bridge stands on piers above the lakeshore, connecting the cities of Suzhou and Jiangsu. It has nine lanes, with space for future expansion.
On December 10, 2005, it was finished. It stretches 32.5 kilometers (20.2 miles) from mainland Shanghai's Pudong New Area to the offshore Yangshan Deep-Water Port in Zhejiang's Shengsi County. The majority of the bridge consists of a low-level viaduct. There are nine large bridges and several small ones along its route.
The world's longest continuous truss bridge, it has 12 spans each weighing about 45 million pounds (20 million kg). The total length of the main part of the bridge is 3.6 miles (5.8 km). It provides an alternative route for vehicles traveling between Shanghai and Hangzhou, the capital of Zhejiang Province. The old southern section of the Jinggang Road, which runs through downtown Guangzhou, is also a continuous truss bridge but only two miles (3 km) long.
It is expected that the life expectancy of this bridge will be more than 50 years. The first phase of the project was completed in 1998 and the second phase in 2005. It took ten years to build the bridge and its construction involved more than 100,000 m² (1,120,000 ft²) of concrete.
The main challenge in building this bridge was its location near the coast. Waves can be very powerful and can damage even a strong bridge. So the designers built the road underneath the sea level so that the bridge would not be exposed to floods.
On April 30, 2005, the Runyang Yangtze River Bridge opened.
It links Zhenjiang City with Yangzhou City and is known colloquially as the Runyang Bridge. The Runyang Yangtze River Highway Bridge began construction on October 20, 2000, and was completed on June 1, 2004. The main project was finished in its entirety on February 2, 2005, and it was formally opened to traffic on April 30, 2005.
This bridge is also a component of the Beijing-Shanghai High Speed Railway. The journey time from Ningbo to Jiaxing has been cut from 4.5 hours to approximately 2 hours since the building of this bridge! ... Grand Bridge Danyang-Kunshan
