The M1, also known as the Fahrettin Altay–Evka 3 Line (), is the only active line of the İzmir Metro in İzmir, Turkey. The line runs from Fahrettin Altay station in the west to Evka 3 station in the east, consisting of 17 stations. Construction of the first stage of line began in 1992 and was completed in 2000, consisting of 10 initial stations. Further extensions of the line since 2005 have been plagued by repeated construction delays and re-awarding of tenders. An eastern extension in 2012 and western extension in 2014 added another two and five stations to the line respectively. As of May 2021, the line is in the process of being extended a further west to Kaymakamlık station, with operations slated to begin in 2023. Plans exist for a further extension to Güzelbahçe in future. All stations on the M1 are handicapped accessible. The line runs almost completely underground with the exception of six stations. Construction Bornova to Üçyol section (1992–2000) The construction of the M1 started in September 1992 with its foundation being laid in December 1994. The Nenehatun tunnels (named after Nene Hatun) between Üçyol and Konak stations were constructed via the New Austrian tunnelling method (NATM), while the Ümmühan Ana tunnels (named after the mother of Süleyman Demirel) between Konak and Basmane stations were constructed via the earth pressure balance tunnelling method. The rolling stock was delivered in August 1996. The first section from Bornova to Üçyol stations was completed in April 2000. Consisting of 10 stations, it began service on 22 May 2000. Üçyol to Fahrettin Altay section (2005–2014) In March 2005, a tender was awarded for the Üçyol–Fahrettin Altay section, a extension to the west consisting of six new stations. The foundation of the extension was laid three months later and tunneling works commenced on 5 July 2005, with the extension slated to be completed in two years. However, when the contractor failed to fulfill their obligations, the İzmir Metropolitan Municipality sent a cease and desist letter to the company on 14 February 2006, subsequently cancelling the tender in November 2006. A new tender was announced on 23 January 2007 with an aim complete the extension by 31 October 2008. The tender was cancelled on 13 August 2009 after the contractor requested a 15-month extension. The İzmir Metropolitan Municipality issued a third tender in October 2009, but it was again cancelled by
