None. With a layout of $2.4 BILLION and an expected profit of $10.4 million, the rate of return is less than 0.5% annually. You would be a fool to sink that much money into it.
The dishonest reports leave out three things: inflation, cost overruns and route changes/upgrades. Bottom line is it will ALWAYS cost more than the initial projections. See the Big Dig.

ALWAYS!
