Pennsylvania Gov. Tom Corbett signed into law a long-awaited $2.3 billion transportation bill, a portion of which will go toward upgrading rail freight lines that serve the Marcellus Shale. The law establishes a fund with money from fee increases, raising the cap on the state's gasoline tax and a transfer from the Pennsylvania Turnpike Commission. In fiscal 2013-2014, $8 million will go toward grants for freight rail improvements, with the rest going to ports, waterways and trails. The Marcellus Shale Advisory Commission said improving rail lines and airports would help ease highway congestion and truck traffic in rural areas.
