The Jiaxing-Shaoxing Sea Bridge ( simplified Chinese : 嘉绍跨海大桥 ; traditional Chinese : 嘉紹跨海大橋 ; pinyin : Jiā Shào Kuà Hǎi Dàqiáo ), sometimes shortened to Jiashao Bridge , is the world's longest and widest multi-pylon cable-stayed bridge. From end to end, it stretches 10.14 km (6.3 mi) across the Qiantang River estuary , at Shaoxing , Zhejiang , China . The main bridge is 2,680 m (8,790 ft) long and 55.6 m (182 ft) wide and carries an expressway with eight traffic lanes. Construction started December 2008, and the toll bridge opened for traffic on July 20, 2013.
22-512: Jiashao is the second sea-crossing bridge built in the greater Hangzhou Bay area. It is about 50 km (31 mi) west of the longer 35.67 km (22.2 mi) Hangzhou Bay Bridge , which opened May 2008, a half year before construction began on the Jiashao. As with the Hangzhou Bay Bridge , the design of the Jiashao had to take into account the raging tidal bore and swift current of
44-512: A multi-level stack interchange connects it with the northern section of the G1501 Shanghai Ring Expressway , before continuing south into Qingpu District . In Qingpu District , it connects with the concurrent G2 Beijing–Shanghai and G42 Shanghai–Chengdu expressways and then passes to the west of Shanghai Hongqiao Airport and Shanghai Hongqiao Railway Station . An interchange with Songze Elevated Road provides access east to
66-421: A relatively small water-blocking area for the 150 piles, which had a small influence on hydrology and avoided the risk of cofferdam construction from the tidal bore. For the main six-pylon bridge foundation, the large pile cap was moved down to below the mud surface of the riverbed, thus presenting only the single pylon column tied directly to the pile cap as the water-blocking area of each of the six main pylons of
88-593: A satellite city of Suzhou , in Jiangsu Province . The expressway also uses the Hangzhou Bay Bridge between Jiaxing and Ningbo , one of the longest trans-oceanic bridges in the world. The expressway passes through the following major cities: In Shanghai , the section of the expressway known as Jiajin Expressway enters the city in Jiading District . It passes to the west of the city centre of Jiading, where
110-699: A service center at the bridge midpoint. It runs across the mouth of Hangzhou Bay connecting the municipalities of Jiaxing and Ningbo in Zhejiang province. One of the longest bridges in the world , it cuts the trip between eastern Zhejiang and Shanghai from 400 to 80 kilometers (249 to 50 miles). The second bridge crossing of the Bay is the Jiashao Bridge , located west of the Hangzhou Bay Bridge, and completed in 2013. It stretches 10.14 km (6.30 mi) across
132-527: Is Xuwen County , in the city of Zhanjiang , Guangdong , because the fixed link to Haikou , Hainan has not been built yet. Once fully complete, the expressway features many other important crossings over bodies of water. The expressway crosses the Yangtze River using the Sutong Bridge , the bridge with the second longest cable-stayed span in the world as of 2012 , connecting Nantong and Changshu ,
154-572: Is complete for the majority of its length except for two major water crossings that have yet to be built. A fixed link across the Bohai Sea is required to join the first missing link from Dalian to Yantai . The construction of a tunnel was announced in February 2011. Second, a bridge has to be constructed across the Qiongzhou Strait from Mainland China to Hainan . Currently, the southern terminus

In 2018, the Zhejiang provincial government, following in Guangdong 's footsteps, released ambitious plans for the Hangzhou Great Bay Area , aiming for a mega urban re-development schema that would double the economic output of the region by 2022 and develop a “world class” bay area in Zhejiang by 2035. The Great Bay Area, an economic and industrial belt centered around Hangzhou Bay,

To roll with the famous Qiantang tidal bore and to reduce the construction risks under difficult hydrologic conditions, the substructure foundation design for the southern and northern bridge approaches called for the elimination of the traditional pile cap and the use of a single pile and flexible column type with a large pile diameter of 3.8m and a very long pile length of 111m. This presented
286-640: The Shenhai Expressway ( 沈海高速公路 ) is an expressway in China that connects the cities of Shenyang , Liaoning , and Haikou , Hainan . When fully complete, it will be 3,710 km (2,310 mi) in length. One of its oldest portions is the Shenyang–Dalian Expressway , or Shenda Expressway ( 沈大高速公路 ) is a 400 km (250 mi) expressway that connects Shenyang and Dalian , the two largest cities of China's Liaoning province. The expressway
308-771: The Zhoushan Islands . This archipelago of islands is urbanized with the administrative status of a prefecture-level city in Zhejiang Province. At less than 15 meters in depth, the entire Bay is relatively shallow. Consequently, the main port in the Bay area is the one in Ningbo and Zhoushan , at the southeast end of the Bay on the coast of East China Sea. The Bay is known for hosting the world's largest tidal bore , up to 9 meters (30 feet) high, and traveling up to 40 km (25 mi) per hour.

It was rebuilt recently and now has 8 lanes. Shenda highway is claimed to be the first expressway in China mainland. It was planned as an express highway but was actually built as a freeway . Due to its length (400 km (250 mi)), it was opened section by section. Although
352-703: The Bay. The Bay extends from the East China Sea to its head at the city of Hangzhou , from which its name is derived. At Hangzhou, the Qiantang River flows into this Bay, providing freshwater from the West while seawater comes in from the East. Thus, Hangzhou Bay, especially its western end, is sometimes called in the scientific literature as the Qiantang River Estuary . At the southeast end of Hangzhou Bay, off Ningbo , are many small islands that are collectively called
374-460: The Qiantang River estuary and carries the [REDACTED] G15W expressway, four lanes each way, over six consecutive cable-stayed spans supported by six tall pylons.
