From the Brooklyn
Bridge, which once carried Brooklyn elevated trains (and streetcars,
and cable cars, long, long ago)
to Manhattan, the pedestrian can get some sweeping views. Here,
a Q or W train plies the Manhattan Bridge into Brooklyn. One
tower of the Williamsburg Bridge appears, further up the river.
In addition to the two suspension bridges that carry transit lines, the
East River is crossed by six different subway tunnel routes between Manhattan
Brooklyn, and four linking Manhattan with Queens; there are an even dozen different
routes the system uses to cross the river.
