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.

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,

264-488: The Qiantang River estuary. 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. The Jiashao Bridge connects Shaoxing on the south shore of the Bay to a point on the north shore of the Bay due south of Jiaxing and provides a more direct route for vehicle traffic between Shaoxing and Shanghai. Another bridge

418-432: The cable-stayed bridge. The main multi-span cable-stayed bridge is 2,680 m (8,790 ft) long from abutment to abutment and is mostly supported by six 227 m (745 ft) tall pylons, each with two sets of two-plane harps of cable stays to sustain two box-girder carriageways, one on either side of the pylons. The two box-girder carriageways are tied transversely to one another for stability and rigidity throughout
