On 10 December 1987, the foundation was laid and construction began on the Jingjintang Expressway (Beijing-Tianjin-Tanggu Expressway) in Daxing, Beijing, which was China's first inter-provincial expressway.

The Jingjintang Expressway starts in the west from the southeast Fourth Ring Road in Beijing City, ends in the east at Tianjin New Port in Tianjin City, spans the two cities and one province of Beijing, Tianjin, and Hebei, connects Beijing, Tianjin and Tanggu, has a total length of 184.4 kilometres, was a key construction project during the state's "7th Five-Year Plan" to "8th Five-Year Plan" period, and was also the first expressway in China built using a World Bank loan through international competitive bidding.

In the bidding process, a total of 32 contractors from 12 countries and regions participated in the bidding, and the contracts were finally awarded to Sino-Japanese and Sino-French consortiums.

The entire Jingjintang Expressway has fully controlled access, uses grade separations, crosses railways at 3 locations along the route, has 10 interchanges with roads, 23 overpasses, 4 large bridges, 28 medium bridges, 337 small bridges, a total of 13 entrances and exits, connects with 2 national highways and 4 other expressways, and has a vehicle speed of up to 120 kilometres per hour.

In many aspects, such as project management, surveying and design, and construction, the Jingjintang Expressway promoted the modernisation of China's expressways.

The Jingjintang Expressway opened a fast-track route from Beijing directly to the port of Tianjin, taking only 1.5 hours to get from Beijing to Tianjin, and together with Beijing Airport and Tianjin Airport it forms a complete "sea, land, and air" transport system.
