The 129 km-long expressway is designed for a speed that, as of May 2004, is the maximum speed legally tolerated on PRC expressways—120 km/h. (The Tianjin part, though, has a lower speed limit of 110 km/h.)
The eastern end links with the Waihuan (Outer Ring) Road in Tianjin, which links to other expressways in the region, such as the Jingjintang Expressway to Beijing and Tanggu, and the Jinghu Expressway to Shanghai.
Three service areas exist along the expressway.
