G15 Shenyang–Haikou Expressway

The expressway passes through the following major cities:

The Shenyang–Haikou Expressway has a branch expressway, the G15W Changshu–Taizhou Expressway, between the cities of Changshu, Jiangsu, and Taizhou, Zhejiang. The branch line splits off from the main expressway after the Sutong Bridge and passes through the cities of Suzhou, Jiaxing, and Shaoxing before rejoining the main expressway just north of Taizhou. The spur line is complete except for a section between Jiaxing and Shaoxing.

The Shenyang–Dalian Expressway was built between 1984 and 1990. The name combines the first character of each of the 2 cities, Shen and Da, making it the Shenda highway. It translates literally to Shenda high-speed roadway. Originally, it was a 4-lane freeway. 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 the entire route was not completed until 1990, its first section had already opened in 1986. By 1988, more than 100 km (62 mi) of the route was opened to public traffic. Its competitor, the Hujia Expressway, only 18.5 km (11.5 mi) long, also claimed to be the first expressway in mainland China. It was completed in 1988.
