- bobthepanda 8y agoCost can be very misleading, since most of the cost of big projects like these tends to be land acquisition. For example, roads are on average much cheaper than rail lines per lane mile of construction, but lots of roads get built in rural or depopulated areas where land is cheaper, whereas rail tends to be built in denser corridors.
