Roadworks exist for parts of the expressway in summer 2005. Road conditions are slightly deteriorating.
It starts just after the Jinzhonglu exit on the Jingjintang Expressway and the Tianjin outer ring road, and heads northeast, gradually heading north, eventually crossing the Jingshen Expressway at Jinwei (Baodi North).
The northern end is close to portions of the Great Wall of China. This very end is going to be linked up to the Jingping Expressway before 2008. The Jinji Expressway would thus form yet another passageway from Beijing to Tianjin.
The expressway has remarkably few exits (the total number is in the single digits) and just one service area. Tolls can get expensive (although prices have recently been slashed). Additional charges apply for vehicles of non-Tianjin licence plates coming into Tianjin, waived only for military and diplomatic vehicles, as well as vehicles on emergency duty.
The expressway cuts through a vast area of emptiness. The scenery heading south is that of plains and farmland. Remarkable also are the design of the toll gates, ranging from the fancy to the downright weird.
