Yongin–Seoul Expressway (Korean용인서울고속도로; part of Expressway 171) is an expressway in South Korea, connecting Yongin, Gyeonggi and Gangnam-gu, Seoul. Informally known as the Gyeongsu Expressway (경수고속도로), it is the only expressway in South Korea not directly connected to another expressway. Although it shares the same designation number, it is not directly connected to Osan-Hwaseong Expressway either. Plans have been made to connect the Busan side of Gyeongbu Expressway and Yongin-side Geumto Tollgate.
