But what happens if the Red Line planners continue on their present course and insist on pushing the current Red Line plan ? Let's go back to the numbers. In December 2012, the MTA announced that $900 million was the maximum amount of federal funding available for the Red Line. While Gov. Martin O'Malley's recent gas tax increase likely saved the Maryland Transportation Trust Fund from insolvency, according to the General Assembly budget analysts, the maximum amount of state funds that could be dedicated to the Red Line is $1.2 billion. Even at the existing estimated cost of the Red Line of $2.67 billion (which the MTA acknowledges does not include the costs associated with moving the planned Harbor East station to Fleet and Exeter Streets and realigning the tunnel west of Little Italy to accommodate the change in station location), the shortfall between the estimated cost of the Red Line and available federal and state funds is almost $600 million. And as MTA executive Henry Kay recently acknowledged, once construction of the tunnel starts, "you never know what you're going to find." The one certainty is that the estimated cost will go up. Mr. Kamenetz's offer to provide $26.5 million in "in-kind" contributions from Baltimore County such as rights of way and minor road realignments amounts to less than 5 percent of the current shortfall.
