Seoul–Yangyang Expressway: Connecting the Capital to the East Coast
The Seoul–Yangyang Expressway serves as a vital transportation artery in South Korea, providing a high-speed link between the bustling capital of Seoul and the scenic Yangyang County. By significantly reducing travel times, this expressway has transformed how travelers access the eastern regions of the country.
Spanning a total length of 150.2 kilometers (93.3 miles), the route operates under the designation number "60." It is managed by the Seoul-Chuncheon Highway Corporation as a privately financed toll road, a status that influences its pricing structure for commuters and tourists alike.

Route Development and Infrastructure
The construction of the expressway was a massive undertaking, costing slightly over 2 trillion won. While the phase from Chuncheon Junction to the East Hongcheon Interchange was completed ahead of schedule on October 30, 2009, the final phase connecting East Hongcheon to Yangyang began in May 2009. The project reached a major milestone when construction was completed on July 15, 2009.
One of the most impressive engineering feats on this route is the Inje-Yangyang Tunnel. This structure holds the distinction of being the longest road tunnel in South Korea, facilitating smoother passage through the mountainous terrain of the region.
Toll Information and Accessibility
Because the expressway is a privately funded toll road, users are required to pay a fee. The standard toll for a passenger car is 5,900 won.
