Jungang Expressway: Connecting South Korea's Central Mountainous Regions
The Jungang Expressway (Korean: 중앙고속도로), which translates literally to "Central Expressway," serves as a vital artery in South Korea's national highway system. Spanning approximately 388.1 kilometers (241.2 miles), this major route traverses much of the country's east-west center line, cutting through scenic and rugged mountainous terrain. As it travels, the expressway passes near significant natural landmarks, including the Chiaksan and Sobaeksan national parks.
Completed in December 2001, the expressway provides essential connectivity between the southern metropolitan area of Busan and the northern city of Chuncheon in Gangwon Province. For travelers moving between Busan and Daegu, much of the route runs concurrently with the Gyeongbu Expressway, creating a high-capacity corridor for national transit.

Route Infrastructure and Specifications
The Jungang Expressway is designed with varying capacities to manage different traffic volumes across its length. The number of lanes fluctuates depending on the specific section, ranging from 4-lane segments to high-capacity 8-lane stretches.
Lane Distribution and Speed Limits
To ensure efficient travel, speed limits and lane counts are optimized for each segment:
- 4 Lanes: Samnak IC to Chojeong IC, Daedong JC to East Daegu JC, and Geumho JC to Chuncheon IC.
- 6 Lanes: Chojeong IC to Daedong JC.
- 8 Lanes: East Daegu JC to Geumho JC.
Speed limits are generally set at 100 km/h for most sections, though the segment between Daedong IC and East Daegu JC allows for a higher speed of 110 km/h.
The Daegu–Busan Expressway Segment
A significant portion of the Jungang Expressway is the Daegu–Busan Expressway. While officially a part of the Jungang Expressway, it is frequently identified by this specific name on various maps. This 82.05 km segment was completed in February 2006 at a cost of over 1 trillion won.
The project, promoted as "I-Way" by the Hyundai Development Company (also known as I-Park), was supported by 30-year loans from the Korean Road Infrastructure Fund, operated by Australia's Macquarie Bank. This segment has revolutionized travel between the two cities, reducing travel time to roughly 1 hour—a saving of approximately 30 minutes compared to the previous route via the Gyeongbu Expressway. The toll for a passenger car is 8,500 won.

Historical Development
The construction of the Jungang Expressway was a multi-decade endeavor. Work began on the Chuncheon to Daegu section on September 20, 1989. Throughout the 1990s, various segments were opened to traffic, initially as 2-lane roads, before being upgraded to 4-lane capacities in the year 2000.
Key milestones include:
- 1994–1995: Opening of several 2-lane sections including Geumho JCT to Chilgok and Chilgok to West Andong.
- 2000: Major upgrade to 4-lane capacity for several central segments.
- 2001: Completion of the main expressway.
- 2006: Completion of the Daegu–Busan segment.
