India boasts of an enormous network of bridges across its length and breadth that connect over rivers, lakes, canals, dams, valleys. Apart from accessibility bridge projects, bridges projects in India that like flyovers, skywalks, and express highways also have been built to improve the nation’s infrastructure that helps to solve various traffic issues like congestion and speedy transport. Bridges play a very important role in the progress of a nation and its people by making way for convenient transport system resolving many accessibility and connectivity issues. Bridges are, in fact, just not infrastructure pillars, they are also reckoned as monuments and heritage symbols of national and international value. Talking of heritage, India is going to build another world record by constructing the world’s highest railway bridge over river Chenab by the year 2016.
Bridges are such structures that incite curiosity in the minds of children and adults alike. Let’s take a walk across some of the common types of bridges found in India based on their construction.
1) Cable Stayed bridge
An example of cable stayed bridge in India is the recently built Bandra-Worli Sea Link that connects Bandra and western suburbs of Mumbai to Worli and central Mumbai.
Cable stayed bridges feature one or more towers from which cables support the road deck.
2) Cantilever Bridge
An example of a cantilever bridge project in India is the Pamban Sea Bridge on the Palk Strait that connects the Pamban island to mainland India. The Pamban bridge is also the first sea bridge in India.
Another notable cantilever bridge in India is The Howrah Bridge or Rabindra Setu(named after Rabindranath Tagore) on the Hoogli river in Kolkata that connects Kolkata and Howrah.
A cantilever bridge is built using cantilever supports which are structures that extend horizontally from a pillar structure.
3) Arch Bridge
An example of arch bridge in India is the Godavari Arch bridge that spans the Godavari river in Rajahmundry. It is being used for running trains by the Indian Railways since 2003.
An arch bridge features an arch shape by its supporting pillars which lets the weight to be carried out along two curved paths toward the ground.
4) Suspension or Hanging Bridge
An example of suspension bridge in India is the Punalur Bridge in Kerala with some mysterious engineering facts like the bridge is connected to four wells using clips.
A suspension bridge features cables that hang from tower to tower across the bridge.
Other than these classifications, you can also know bridges as rail-cum-road Bridges, road bridges, rail bridges, flyover, highways, expressways and skywalks.
An example of rail-cum-road bridges projects in India is the Brahmaputra bridge built over river Brahmaputra that connects the north-eastern states of India with the rest of India. The Brahmaputra Bridge is also the first of its kind in India.
One of the longest railway bridges in India, The Vembanad Rail Bridge in Kerala is an example of a rail bridge.
Skywalk has been a recent addition in the types of bridges in India but is only a new concept of the old pedestrian bridge. These are mostly found in cities like Mumbai.
