The line first began running from Munyang to Sawol on 18 October 2005, a distance of 29 km (18 mi). The line had been scheduled to open some years earlier, but fallout from the IMF crisis of the late 1990s caused delays in construction.

On 19 September 2012, the extension from Sawol to Yeongnam University opened.

Daegu Metro Line 2 will be expanded from Munyang Station to Seongju County as compensation of Terminal High Altitude Area Defense Deployment.
