Filling In The Holes From The Big Dig

From the Boston Globe: "While the Big Dig spent $100 million on parks - including North Point Park in Cambridge, Paul Revere Park in Charlestown, and Nashua Street Park in Boston - it failed to build the all-important links between the parks, the Esplanade, the Greenway, and the Harbor. As a result, the parks have seen little use.

Those missing links all lie in the so-called lost half-mile of the Charles River, officially known as the New Charles River Basin.
