In addition to the above revised assumptions, this scenario includes several additional assumptions related to tolls and traffic volume.
Assumptions
■ Average $2.00 each way toll beginning in 2013 growing at 2.5% each year (same as Base Case).
■ Opening year average daily traffic on 47,000 (the high end of the range provided for in the "New Mississippi River Bridge Funding Analysis" traffic study), growing at 2.5% per annum throughout the concession period.
A preliminary valuation of a Mississippi River Bridge Project concession given the above "Aggressive Case" parameters and a $2.00 initial toll indicates a value range of approximately $690-950 million.
