History
editConstruction of the expressway began in 1969, and it opened in 1972. In 1985, it was extended to Haengju Bridge and Cheonho Bridge. At the time the road was completed, it had sections with two, three, and four lanes.
After rapid economic growth and the 1988 Summer Olympics the road was the site of chronic traffic jams. An expansion project began in 1989 and was completed in 1998.
In 2012, Seoul City was expanded and road improvement projects were proposed to the Gangbyeon Expressway, including the underground relocation of the road construction.
