Question: 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
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 |
