The pursuance of these projects will also have some costs and negative externalities. During the development of the transport infrastructure, the government will incur costs of destroying the environment and moving the locals in order to get the space for expanding the projects. Moreover, destruction cost to the natural resources like rivers, trees and other resources cannot be easily determined. The increased number of automotives would increase the level of air pollution whose long term impact is hard to determine. Besides, the government must discount the future benefits and costs to determine the net present value. The rate of discounting the future benefits and the costs will pose the greatest challenge to the government (Mikesell, 2011).
