Howrah Bridge

The Howrah Bridge situated over the Ganga River, it also called the Hooghly River in West Bengal. Started in 1943, it is still popularly known as Howrah Bridge.

Howrah Bridge another name is "Rabindra Setu"

The Howrah Bridge is a famous joint point between of Kolkata and Howrah of West Bengal. Other bridges are the Vidyasagar Setu, Vivekananda Setu, and the newly constructed Navadita Setu. The Bay of Bengal region sees storms with around 100 million vehicles per day and possibly more than one and a half million pedestrians on board, making it easily the busiest cantilever bridge in the world. The third-longest cantilever bridge at construction, the Howrah Bridge is currently the sixth-longest bridge of its kind in the world.

History of Howrah Bridge

In 1862, the Bengal government asked George Turnbull, the chief engineer of the East Indian Railway Company, to study the feasibility of the bridge over the Hooghly River. He recently established the company's rail terminus at Howrah. He reported on 19 March with extensive illustrations and estimates:

In Calcutta, the foundation of the bridge will be quite deep and expensive due to the depth of mud there.

A ) Shipping barriers will be sufficient. A good location for the bridge was "a dozen miles north of    Calcutta" on the Palta Ghat where "a hard mud bed was not found at any depth below the river bottom".

B) One Suspension - The girder bridge would be ideal with five spins and two spans.

The bridge was built.

Something about "Pontoon Bridge"

In view of the increasing traffic across the Hooghly River, a committee was formed in 1855-56 to examine the options for construction of the bridge. The project was saved in 1859–60, to be restored in 1868, when it was decided to build a bridge and a newly appointed trust to build it. The Calcutta Port Trust was established in 1870, at that time the bridge was 1528 feet long and 62 feet wide, with a 7 feet wide path on either side. But the entire structure was occupied and formed. It used 26,500 tonnes of steel, of which 23,000 tonnes of high-tensile alloy steel, known as tuscaram, was supplied from Tata Steel. The main tower was built with 21.3 shafts, each with dimensions of 55.31 x 24.8 meters of single cottons in 6.25 meters square. Mr. J. is the Chief Engineer of the Port Trust, McGlashan needed to supplant the boat connect with a changeless structure, as the current scaffold meddles with north/south waterway traffic. The work could not be started with the onset of World War I. Then in 1926 a commission headed by Sir RN Mukherjee recommended a special suspension bridge across the Hooghly River. The bridge was designed by Mr. Randall, a Palmer and a Triton Mr. Walton. M / s. The Cleveland Bridge & Engineering Company was ordered to build and build in 1939. Intervened in World War II. All steel coming from England was replaced in the war effort in Europe. Out of the 26,000 tonnes required for the bridge, only 3000 tonnes were supplied from England. Despite the Japanese threat, the then Indian government insisted on construction. Tata Steel was asked to provide the remaining 23,000 tonnes of high tension steel. Tata developed the steel standard required for the bridge and called it Tekam. At that time, the entire 23,000 tons were supplied. A local engineering firm in Howrah: Breitright, Burn & Jessop Construction Company was commissioned and commissioned. Both anchor cases were 8.4 meters in 16.4 meters with two wells measuring 4.9 meters. The cast was designed so that the working chambers inside the shaft could be temporarily attached via a steel diaphragm to allow the compressed air to work. While the bees were being cleaned, a wide variety of items were recovered, including langar, pair iron, cannon, cannon, brass utensils and coins from the East India Company. 

Caesars were submerged at a rate of 24 hours per day or more.

Description  and Specifications of "Howrah Bridge"

Hooghly Bridge

When operated in 1943, the Howrah was the third longest cantilever bridge in the world, a major cause of overkill, although vehicles up to 15 tons were allowed on the structure, but 12-18 wheeled vehicles. And vehicles carrying 25 tons of load often go over it. After 31 May 2007, overload trucks were banned from operating on the bridge, and were diverted to Vidyasagar Setu. The road is 15 feet wide and is paved with pedestrians.

Erosion occurs due to birds falling and spitting on humans. An investigation in 2003 showed that long-term chemical reactions occurred as a result of continued accumulation in bird excreta, causing damage to many joints and sections of the bridge.

Pedestrians, lime-mixed stimulants have severely damaged the bridge to pedestrians. A technical inspection by Port Trust officials revealed in 2011 that the thickness of the steel boxes protecting the pillars had decreased from six to three millimeters. Damage to cross girders and hangars, and poles can endanger bridge safety. Kolkata Port Trust announced that it would spend steel pillars covered with fiberglass cases to avoid sputtering.

      On June 24, 2005, MV Mani, Ganga Water Transport Pvt. Ltd., trying to pass under the bridge during high tide, and its chimney was stuck under three hours, causing a loss of about $ 15 million to the length of the oven and bridge. Some of the 40 cross-graders were also disbanded. Two of the four guides on the trolley, welded with bolts and grinders, suffered extensive damage. Almost the track was curved beyond repair. The damage was so severe that PTT requested assistance from the original consultant Randall Palmer & Triton Ltd on the bridge coming from Britain. “Kolkata Port Trust” also approached SAIL in 1943 for the 'matching steel' used during its construction. For this repair, which costs about 8 tons of steel. The repairs were completed in early 2006.
