Chile’s president Michelle Bachelet has unveiled a new US$4.2-billion plan to expand Santiago’s metro. Chile will contribute US$2.2 billion towards the new Line 7 with the remainder coming from private investors, she said. Other metro plans call for lengthening by 3.8 km the 22-km-long Line 3, currently under construction, and extending by 5 km the existing Line 2 at an overall cost of US$1.17 billion. It was not clear whether these latter two projects would be P3s.
