Argentina is considering the construction of a bridge across the "Rio de la Plata" river to connect its northern coast to the southern coast of Uruguay. If this bridge is constructed, it will reduce the travel time from Buenos Aires (Argentina) to Sao Paulo (Brazil) by over 10 hours and has the potential to significantly improve the flow of manufactured goods between the two countries. The cost of the new bridge, which will be the longest bridge in the world and span over 50 miles, will be $705 million. The bridge will require annual maintenance of $10 million for repairs and upgrades and is estimated to last 80 years. It is estimated that 550,000 vehicles will use the bridge during the first year of operation and an additional 50,000 vehicles per year until the 10th year. These data are based on a toll charge of $90 per vehicle. The annual traffic for the remainder of the life will be 1,000,000 vehicles per year. The Argentinian government requires a minimum rate of return of 15% in order to proceed with the project. a) Calculate NPV, IRR, and the payback period. What would you advise the Argentinian government based on the NPV and IRR of this project? (40pts.) b) Would your recommendation change if Argentina could borrow up to 65 percent of the cost ($455 million) at a 4 percent interest rate from the World Bank (paid in annual payments over a 50-year period)? (40pts.) c) What other considerations are there in deciding whether or not to construct the bridge? (20pts.)

10-7. A toll bridge across the Mississippi River is being considered as a replacement for the current I-40 bridge linking Tennessee to Arkansas. Because this bridge, if approved, will become a part of the U.S. Interstate Highway system, the B–C ratio method must be applied in the evaluation. Investment costs of the structure are estimated to be $17,500,000, and $325,000 per year in operating and maintenance costs are anticipated. In addition, the bridge must be resurfaced every fifth year of its 30-year projected life at a cost of $1,250,000 per occurrence (no resurfacing cost in year 30). Revenues generated from the toll are anticipated to be $2,500,000 in its first year of operation, with a projected annual rate of increase of 2.25% per year due to the anticipated annual increase in traffic across the bridge. Assuming zero market (salvage) value for the bridge at the end of 30 years and a MARR of 10% per year, should the toll bridge be constructed? (10.7) 10-8. Refer back to Problem 10-7. Suppose that the toll bridge can be redesigned such that it will have a (virtually) infinite life. MARR remains at 10% per year. Revised costs and revenues (benefits) are given as follows: (10.7, 10.9) Capital investment: $22,500,000 Annual operating and maintenance costs: $250,000 Resurface cost every seventh year: $1,000,000 Structural repair cost, every 20th year: $1,750,000 Revenues (treated as constant—no rate of increase): $3,000,000 a. What is the capitalized worth of the bridge? b. Determine the B–C ratio of the bridge over an infinite time horizon. c. Should the initial design (Problem 10-7) or the new design be selected?
