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.
