The first phase of Metro Line 4, which includes four stations, will be officially inaugurated on 25 January, a Transport Ministry source tells Al Mal. Work on the first phase of Line 4 began in 2015. The government will also announce new ticket prices for Line 3 on Friday, the source said. Line 3 currently includes nine stations, but is planned to eventually include 13. Earlier this week, local news reported that the National Authority for Tunnels had called off its tender for construction works on phase one of Metro Line 4 due to expensive offers.
