The government will build billboards and rent them to advertisers along the road. Length Construction cost Annual O&M cost Study period Number of billboards Around the Mountain 22 miles $21 million $140,000/yr Through the Mountain 10 miles $45 million $165,000/yr 40 years 30 40 years Zero due to high winds Rent of each billboard per year = $60,000 per billboard per year Estimated volume of traffic = 400,000 cars per year (these cars operate at $0.25 per mile).
