The Economic Feasibility of Rebuilding Al-Isra University Tunnel — Mechanical Factors

Economic feasibility is the cornerstone in the decision making on an economic venture. The more positive the economic signs, the less the risk and foreseen losses. This study throws light on some economic advantages of rebuilding Al-Isra tunnel, especially in terms of shortening the car/bus trip by six kilometers go and fro, and in terms of reducing the trip schedule by five minutes. That is by using an alternative road through one of the present tunnels available on the way to the university. The study makes also a comparison between the construction cost and the emanating benefits in terms of saving time and vehicle operation. The sensitivity analysis shows that the B/C ratio is 3.05, and in worst cases it is 2.03. While these results definitely prove the economic feasibility of the project, they also point to the risk reduction of traffic accidents, due to road shortening.
