Three tugs tow the new Willlis Avenue Bridge span from West Hurley, up the Hudson near Albany, on its way down to its new position on the Harlem River. After a couple of weeks in Bayonne they will take it through the East river to its home on the Harlem River? The Times account is HERE.
Below is a shot I took a few years ago of the new 145th Street bridge ready to be put in place. The Willis Ave. bridge is more than twice the weight. But as one of the guys from Mammoet the Dutch outfit handling the transport said: "It's simple if you have the right tool".
