On 5 August 2015, South Korean President Park Geun-hye attended a ceremony launching work on the reconstruction of the 9.3 km (5.8 mi) Baengmagoji–Woljeong-ri section of Korail's Gyeongwon Line, which has been closed since the Korean War, as part of events marking the 70th anniversary of the partition of Korea. The works are to begin in October and are expected to be finished by 2017; the US $129 million project is being funded by the Unification Ministry. Park also stated her hope that the remaining 2.4 km (1.5 mi) section across the DMZ would be rebuilt soon, which would re-establish the old Kyŏngwŏn Line connecting Seoul to Wŏnsan.
