Answer: Howrah Bridge
In West Bengal, India, the Howrah Bridge connects the twin towns of Howrah and Kolkata.
The 705m-long and 30m-wide bridge over the Hooghly River was erected in 1943. In June 1965, it was renamed Rabindra Setu after the first Indian Nobel laureate, Rabindranath Tagore. The bridge is generally referred to as Howrah Bridge.
The Howrah Bridge, which cost an estimated Rs25 million to build, opened in February 1943 and presently handles around 100,000 vehicles and over 150,000 people daily. It is the world’s sixth-longest cantilever bridge.
The Howrah Bridge is a balanced cantilever suspension bridge. It includes a 1500-foot middle span between the main towers. The lengths of the anchor and cantilever arms are 325ft and 468ft, respectively.
The suspended span is 564 feet long. The major towers rise 280 feet above the monoliths and are 76 feet apart at the peak. The bridge deck is 71 feet wide and has two 15-foot pathways on either side.
The superstructure is made up of riveted parts made of high tensile and mild steel. The bridge deck descends from panel points in the middle of the towers to hungers in the lower chord of the main trusses.
The deck level articulation joints were rebuilt in 2008, and the bridge was lighted in gold and magenta in November 2006.
Kolkata Port Trust (KPT) committed Rs35 million in the project to build 13 kilometres of cable, 700 lights, a new control tower, and a substation. In 2005, the bridge’s maintenance cost was around Rs27.3 million.
The pylons, steel-lattice inner structure, under-deck, and roadway were all lit up with white LEDs, while the upper structure was lit up with blue LEDs.
The bridge, which was painted in June 2005, required more than 26,500l of aluminium paint to cover 23,500t of steel with a surface area of 2.2mm2.
