South Korean highways experienced significant traffic congestion this week as travelers returned to Seoul during the peak summer vacation period [1].

Seasonal travel spikes often strain the national road infrastructure, causing delays that impact logistics and commuter travel across the peninsula. The current congestion highlights the recurring pressure on primary arteries connecting the capital to southern provinces.

Field reporter Kim Yi-young of YTN News said that while congestion on roads heading toward provincial areas has largely cleared, the flow toward the capital remains restricted [1]. On the Gyeongbu Expressway, the Seoul-bound direction saw congestion spanning 25 km [1], while the Busan-bound direction experienced a nine km delay [1].

The Yeongdong Expressway also faced disruptions, specifically near Dongsuwon. Seoul-bound traffic on this route stretched for 17 km [1]. In contrast, the Gangneung-bound direction remained relatively clear with only one km of congestion [1].

Across the national highway network, the total length of congested sections reached 54 km [1]. However, the disparity between directions was stark, as the Seoul-bound direction alone accounted for 86 km of slow-moving traffic [1].

Traffic was particularly dense near the Cheongju Rest Area on the Gyeongbu line [1]. The surge in vehicle volume is attributed to families completing their summer holidays and returning to the metropolitan area [1].

"The Gyeongbu line is experiencing congestion over a 9 km section toward Busan and a 25 km section toward Seoul," Kim said [1].

Regarding the broader network, Kim said, "Out of the total, 54 km are blocked, but conversely, traffic is frustrating over an 86 km section in the Seoul direction" [1].

“Seoul-bound traffic on the Yeongdong Expressway stretched for 17 km.”

The concentrated congestion toward Seoul underscores the centralized nature of South Korea's travel patterns, where holiday surges create asymmetric bottlenecks. The significant difference between the 54 km of overall congestion and the 86 km of Seoul-bound delays suggests a tidal wave of traffic that exceeds the capacity of the primary expressways during the vacation wind-down.
