Post probe reveals MTA's wasteful spending on Second Ave. subway extension.

The Metropolitan Transportation Authority (MTA) is spending billions of dollars more than necessary to extend the Second Avenue Subway to East Harlem due to design decisions for building stations twice as big as necessary, according to a New York Post investigation. The MTA plans to spend $7 billion, a figure that could grow to $7.7 billion, while similar projects in European cities could be built for just $2-$2.3 billion. The MTA's overspending leaves New York unable to afford major subway expansions, even as it struggles with high traffic and asthma rates.
