The Gangbyeon Expressway (Korean: 강변북로) is an eight-lane highway located in Seoul, South Korea.

This route connects Seoul to Namyangju, with a total length of 37.37 km (23.22 mi).

The highway is directly connected with the Jayu Motorway (자유로) in the border city located on the Gayang Bridge.

The highway is the main arterial road that connects northern Seoul with satellite cities such as Goyang, Paju, and Namyangju.

After rapid economic growth and the 1988 Summer Olympics the road was the site of chronic traffic jams.
