An underwater tunnel was designed to ease the trip for people traveling between New York and New Jersey one of America's busiest commuter corridors. But New Jersey Governor Chris Christie, coping with the financial pinch of the recession, deemed the tunnel unworthy of state money and killed the project. While some hailed the decision as a necessarily austere measure in tough economic times, critics said investment in such infrastructure projects the tunnel had been America's largest public-works project in development is exactly what the country needs. In any case, the tunnel appears to be halted indefinitely, but a cheaper alternative has already been proposed: an extension of New York City's 7 train all the way to New Jersey, which would directly link the Garden State to the city's subway system for the first time.
