Alexander Hamilton Bridge HistoryAlexander Hamilton Bridge History
A new eight-lane arch span was
proposed - the Alexander Hamilton
Bridge – to connect the Trans-
Manhattan and Cross-Bronx
Expressways.
Currently, estimated traffic
over the Hamilton Bridge
is over 188,000 vehicles
per day.
The Alexander Hamilton
Bridge has not undergone
major repair since it opened
on January 15, 1963.
In 1955, Robert Moses determined that
the 181st
Street Bridge would not be able
handle the anticipated traffic demands
from the proposed lower level of the
George Washington Bridge.
