By the late 1990s, Iranian engineers for the ultimate southern destination had planned the area of Bandar Abas, more specifically the Minab Valley, and then the route shifted eastward to the Macau valleys of the Kašan River in Džaskanski or Kahir in Čabaharský okrug.
Do kasnih 1990-ih iranski inženjeri za krajnje južno odredište planirali su okolicu Bandar-e Abasa, konkretnije dolinu Minaba, a potom je trasa pomaknuta istočno prema makranskim dolinama rijeke Kašani u Džaskanskom ili Kahir u Čabaharskom okrugu.
