Part of the project was the replacement of a branch to Daegu Airport from the old alignment with a spur line paralleling the highway west from Cheongcheon to the airport, finished a year later. The Daegu Line was considered for an upgrade to a double -tracked, electrified railway in a straighter, long alignment from 2000. Detailed plans were prepared by 2009, the foreseen budget was 988.042 billion won, and the completion of the project was set for 2017.
