Engineer working in the Transportation Planning Department for the State of West Virginia have identified three viable sites for a new bridge across the Ohio River. All three sites are within 15 miles of each other, but the land and construction costs vary. The bridge that would directly link the cities on opposite sides of the river would have the lowest travel costs, but it would also have the highest construction cost because of property value. The bridge location just north of the two cities would involve less travel time than the one to the south. The costs associated with each bridge are shown. At an interest rate of 6% per year, determine which location is preferred, assuming the bridged will be permanent. Use a b/c procedure to find the best alternative
