Two different routes are being considered for a mountain highway. the high road would require building several bridges and would navigate around the highest mountain points, thus requiring more roadway. the low road would construct several tunnels for a more direct route through the mountains.Projected travel volume for this new section of road is 2500 cars per day. Use the modified B/C ratio to determine which alternative should be recommended. Assume that project life is 45 years and i=6%.

HIGH ROAD LOW ROAD
Construction cost/mile $200,000 $450,000
Number of miles required 35 10
Annual benefit/car-mile $0.015 $0.045
Annual O&M costs/mile $2,000 $10,000
