The steep population rise in the 21st century has caused major congestion problems for the city's roads. In efforts to tackle this issue, a 95 km outer ring road costing $110 million was approved in 2017. Construction will take five years and it will run from Char Asiab via Ahmad Shah Baba Mina, Deh Sabz ("Kabul New City" development area), the AH76 highway, Paghman and back to Char Asyab. A new bus public transport service is also planned to be opened in 2018 (see below). In September 2017, the head of the Kabul Municipality announced that 286 meters of pedestrian overpass footbridges will be built in eight busy areas "in the near future".
