The Manhattan Bridge is a
suspension bridge that crosses
the East River in New York City,
connecting Lower Manhattan with
Brooklyn. The bridge was opened
on December 31, 1909 and was
designed and built by Polish
bridge engineer Ralph Modjeski
with the deflection cables
designed by Leon Moisseiff, who
later designed the infamous
Tacoma Narrows Bridge in 1940.
It has 4 vehicle lanes on the
upper level (split between two
roadways), and 3 vehicle lanes,
4 subway tracks, a walkway and a
bikeway on the lower level. The
upper level has 2 lanes in each
direction, and the lower level
can be one-way in peak direction
or have 2 lanes in one direction
and the other in the opposite
direction. It once carried New
York State Route 27 and later
was planned to carry Interstate
478. No tolls are charged for
motor vehicles to use Manhattan
Bridge.
