南京地铁1号线全长21.72km,工程总投资近85亿元人民币,综合造价仅为3.92亿元/km,远低于国内已经建成的其他地铁的造价(5.6亿元/km),这主要得益于南京地铁国产化程度的大幅提高,以及土建工程招标中的充分竞争。南京地铁票价目前正式确定为2元、3元、4元,其中2元可以乘坐8个车站?
The total length of Nanjing Metro Line 1 is 21.72km, with a total investment of nearly 8.5 billion RMB. The comprehensive cost is only 392 million yuan / km, much lower than the cost of other subway projects in China (560 million yuan / km) Thanks to the substantial increase in the localization of Nanjing Metro and the full competition in civil engineering bidding. Nanjing Metro fares currently officially identified as 2 yuan, 3 yuan, 4 yuan, of which 2 yuan can take 8 stations?
