Yongin–Seoul Expressway
# Yongin–Seoul Expressway

Yongin–Seoul Expressway (Korean: 용인서울고속도로, part of Expressway 171) is an expressway in South Korea, connecting Yongin, Gyeonggi and Gangnam-gu, Seoul. Informally known as the Gyeongsu Expressway(Korean: 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.

## History

The expressway was designed to reduce traffic on the Gyeongbu Expressway with the expansion of Southern Gyeonggi. Construction started in October 2005, and was completed on July 1, 2009. The opening ceremony occurred on 30 June 2009, with Gyeonggi governor Kim Mun-su in attendance. The expressway has been open to traffic since midnight on July 1 (KST). It was built to order and is operated by Kyeongsu Expressway Corporation for 30 years. 1.5 trillion won was spent to build this expressway, with Kyeongsu Expressway Corp investing 570 billion won.

Traffic from Heungdeok interchange and Gwanggyo-Sanghyeon interchange leaving W. Suji Tollgate pay an additional 600 won. The same applies for vehicles entering W. Suji in the direction of Heungdeok.
