Brooklyn Bridge

Introduction and History

The bridge located in Manhattan and Brooklyn, New York, USA. The construction work for the

bridge was started in 1869 and completed within 14 years, in 1883. The total estimated cost

occurred for the construction of bridge was $18 million at that time. The was considered as the

brilliant accomplishment of engineering of the 19th century, which total length is 3,460 feet with

a longest single span of 1,595 feet. The bridge was the first ever suspension bridge, which have

been made by steel cable wires. The engineers John A. Roebling and his son Washington A.

Roebling used steel and granite as the materials for the bridge. The engineers used dangerous

explosives underwater, which they called Caisson. At that time, it was considered as the longest

bridge of the world.

Challenges Met By the Brooklyn Bridge

In the early 1800, it was considered as the dream of making large bridge on the East River. The

idea was to provide advantage to joint cities New York and Brooklyn. However, this idea was

thought to be impossible because the width of East River was too large to cover maximum of it.

The East River was salt-water estuary, have tidal conditions and prone to turbulence. Further

challenges that the bridge had faced was that the East River considered as the busiest River in the

World because hundreds of crafts with all sizes cross the bridge any time and it is general rule

that any bridge spanning the water should allow the ships to cross beneath it, which means

bridge needs high suspension that was the only practical solution rest with the engineers at that

time to made largest bridge ever in the New York.

Questions about the Structure of the bridge

The Brooklyn Bridge is now considered as one of the 166 bridges, which are structurally

deficient and the reactions and responses of the residents of the New York state put the bridge in

the category of that bridge, which was collapsed into the Mississippi River. According to feds

rating system, Brooklyn Bridge was rated less than the troubled Willis Ave and the Minneapolis

Bridge. The Brooklyn Bridge got awful ranks from the state of New York and called that a

bridge with poor condition, which have rusting steel joints and worsening bricks and mortar on

the ramps. The biggest problem now considered for the bridge is roadway deck on the

approaches of Brooklyn and Manhattan. However, it does not a matter to shut down the bridge

for the traffic even with the poor rating from the residents of the state like the country did with

Williamsburg Bridge in 1988. The Brooklyn Bridge was provided the lowest rating of zero

because of safety, serviceability, structural adequacy, and functional obsolescence.
