A relocation of a short stretch of rural highway feeding into Route 390 northwest of Dallas is to be made to accommodate new growth. The existing road is now unsafe, and improving it is not an alternative. Alternate new route locations are designated as East and West. The initial investment by government highway agencies will be $3, 950,000 for East and $5, 500,000 for West. Annual highway maintenance costs will be $120,000 for East and 590,000 for the shorter location West. Relevant annual road user costs, considering vehicle operation, time end route, fuel, safety, mileage, and so on, are estimated as $880,000 for East and only $690,000 for West. Assume a 20 year service life and i = 7 %. C 1. What is the present worth of the benefits and costs of route West over route East? PW benefits of route West over route East: $ PW costs of route West over route East: $ Carry all interim calculations to 5 decimal places and then round your Final answer to the nearest dollar. The tolerance is plusminus 50. Using incremental D/C ratio analysis, which alternative should be selected?
2. Compute the appropriate B/C ratio(s) and decide whether East or West should be constructed.
