The Port Authorities of New York and New Jersey estimate that the annual net revenues for the George Washington Bridge (GWB) will total $13M by the end of this year (t=1). At the end of three years (t=4) you expect a toll increase of 10%. Revenues will then remain constant for the next 6 years (year 4 through 10). Because the GWB is such an important artery for the New York City area, the Port Authorities would like to reinvest this revenue in a comprehensive maintenance and repair program. However, it will take two years (t=3) before plans and specifications can be developed and contracts awarded. What is the annual amount the Port Authorities should expect to spend for a five-year contract (uniform cash flows starting at the end of years 3 through 7)? The Port Authorities use a MARR of 7% for all public works projects.
