Beginning in the 1970s, Ashgabat's boundaries shifted outward, with the aforementioned municipalities annexed, the aerodrome at Howdan redeveloped, and creation of the Parahat () neighborhoods to the south and industrial parks to the east. In 2013, Ashgabat annexed a portion of the then-Ruhabat district of Ahal Province as well as the city of Abadan (previously named Büzmeýin, and renamed that as a neighborhood) plus all land and villages in between. The southern boundary of Ashgabat was extended southward to the foothills of the Kopet Dag mountains. Overall, Ashgabat's land area rose by 37,654 hectares. The following municipalities were abolished due to their incorporation into the city of Ashgabat: city of Abadan, towns of Jülge and Ruhabat, villages of Gökje, Gypjak, Birleşik, Magaryf, Herrikgala, Ýalkym, Gurtly, Hellewler, Ylmy-Tejribe bazasy, Ýasmansalyk, Köne Gurtly, Gulantäzekli, Serdar ýoly, Gaňtar, Gyzyljagala, Inerçýage, Tarhan, Topurly, and Ussagulla. A further expansion occurred January 5, 2018, when additional land to the north was annexed, incorporating the Gurtly Reservoir and two greenfield residential construction projects, known today as Täze Zaman. This statute also established the current four boroughs of Ashgabat.
