G15 Shenyang–Haikou Expressway
expressway in Liaoning, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Guangdong and Hainan provinces, China
The Shenyang–Haikou Expressway (Chinese: 沈阳—海口高速公路), designated as G15 and commonly referred to as the Shenhai Expressway (沈海高速公路) is an expressway in China that connects the cities of Shenyang, Liaoning, and Haikou, Hainan. It is 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 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 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, a satellite city of Suzhou, in Jiangsu Province.
This brief starts where responsible research should: with the source description of “G15 Shenyang–Haikou Expressway” as expressway in Liaoning, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Guangdong and Hainan provinces, China. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as expressway in Liaoning, Shandong, Jiangsu, Shanghai, Zhejiang, Fujian, Guangdong and Hainan provinces, China. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 3, 2026. The linked authority identifier is Q785443. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2011 and 2012.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
