The Seoul–Yangyang Expressway (Hangul: 서울양양고속도로) is an expressway in South Korea, connecting the cities of Seoul and Yangyang County. It is 78.5 kilometers long, with two lanes of traffic in each direction and ten interchanges. It shares the number "60" and operates by Seoul-Chuncheon Highway Corporation, as a privately financed toll road. The extension to the end at the eastcoast ist under construction and planned to be open end 2015.
The estimated travel time between the two cities is roughly 40 minutes, saving about more than half of the previous travel time on the National Road No.46. Due to the reason as a 'privately funded' road, the toll for a passenger car is 5,900 won, and after lots of complaints from the people and organizations of Northwestern Gangwon, the toll for the user living in Chuncheon city and its surrounding region will be 5,200 won.
Construction was completed on July 15, 2009, with an active passenger-passing and its official opening ceremony held on the same day, at a total cost of slightly over 2 trillion won. According to the South Korean Governmental decision made on December 2002, its original name is Seoul-Yangyang Expressway, however, it will be expanded completely on 2014, because, though the construction of a phase from Chuncheon Junction to East Hongcheon Interchange finished (earlier than expected) on October 30, 2009, by public-funded KEC, its last phase, East Hongcheon to Yangyang has just recently been started on May 2009.
Gapyeong County Bus No. 8004, Gwangju Urban Bus No. 8002, and Namyangju Urban Bus No. 8012 use this highway.
