G1511 Rizhao–Lankao Expressway

The G15 11 Rizhao–Lankao Expressway, commonly referred to as the Rilan Expressway , is a 472.36 km that connects the cities of Rizhao, in the province of Shandong, and Kaifeng, in the province of Henan. The expressway is named after the two localities at its termini, Rizhao, to the east, and Lankao County, a county under the administration of Kaifeng, to the west. Despite this namesake, the expressway's western terminus is actually in Xiangfu District, a neighbouring district in Kaifeng.

The expressway is a spur of G15 Shenyang–Haikou Expressway.
