History The construction of Daegu Metro was recommended to the city after the City of Daegu conducted the research in 1985 to find the ways to improve the city's transit. Following the establishment of the committee to oversee the new metro transit construction in September 1989, the study was conducted from 1989 to 1990 to evaluate whether the construction project was feasible. The guidelines for the metro transit's construction and operation was approved in January 1991. While the guideline focused on solving the traffic issues due to the overpopulation of the downtown area, it set the consequent goals of improving the city with more efficiency resulting from shorter commuting times, cleaner environment with reduced auto traffic and energy expense, larger outreach to bring the transit to those outside the urban area, and improved transportation capacity. Line 1 The construction of Daegu Metro Line 1 began in December 1991 and the first 10.3km long section between Jincheon and Jungang-ro began on November 26th, 1997. After the second long section of Line 1 between Jincheon and Ansim opened on May 2nd, 1998, the extension was made to Daegok towards south in May 2002. The most recent extension was made from Daegok to Seolhwa in 2016, making Line 1 long with 32 stations. The line serves its function to connect the southwestern area of the downtown to the city's east. Line 2 The construction of Line 2 began in December 1996 and was completed on October 18th, 2005 with the long section between Munyang and Sawol. In June 2007, the line was extended to connect the three newly built metro stations in the neighboring city of Gyeongsan. Another construction to add the long section to the line from Sawol to Yeungnam University of Gyeongsan was completed in September 2012. As of now, the line is long with 29 stations. Line 3
