Chennai: Bridges in India, such as Bandra-Worli Sea Link (5.6 km long, 126 m above water level), Hajira Creek Bridge (1.4 km long, 25 m above water level), Vizag-Seethampeta Railway Bridge (2.3 km long, 20 m above water level), and under constructed Mumbai Trans Harbour Link (21.8 km long, 25 m above water level), Chenab River Railway Bridge (1.3 km long, 359 m above water level) etc. are testament to its civil engineering and architectural capabilities.
They showcase engineering excellence and innovative designs despite myriad technical challenges and geographical constraints encountered within the execution of such projects.
Among all these projects critical to national economic growth, the Pamban Railway Bridge, an engineering marvel, located in the state of Tamil Nadu, occupies a special place as it is a remarkable feat of engineering that connects the town of Rameswaram to the rest of India.
Spanning over 2.3 kilometres, this bridge provides a crucial mobility link between the island of Rameswaram and the mainland. This railway bridge, one of the longest sea bridges at that time, was constructed in 1914 by the British colonial authorities to facilitate the transportation of goods and services and was designed by German engineers and took nearly five years to completely operationalise.
The bridge is supported by 145 concrete piers, each spaced at 15-meter intervals. The bridge's design permits the navigation of ships and boats beneath, with a clearance of 12 meters above sea level. The bridge's sui generius lifting span allows ships to pass through, making it a remarkable feat of technological design and engineering. It is not only vital for trade, business & economics but also paves the way for smooth movement for pilgrims visiting the famous Rameswaram Temple.
The bridge has played a significant role in supporting the local economy through tourism and enabling the transportation of seafood, textiles, and other goods. Nevertheless, of late, the Pamban Railway Bridge has faced numerous challenges owing to corrosion, structural damage, cracks, and a multitude of other maintenance issues.
To address these concerns, it is heartening that the Indian Railways has undertaken several timely upgrade initiatives and renovation projects, including the replacement of the lifting span and revisiting of the bridge's foundation for strength.
It would not be out of place to state that the Pamban Railway Bridge is an iconic landmark and an engineering marvel that has stood the test of time. Its construction and maintenance have ensured the connectivity of Rameswaram to the mainland, supporting the local economy and facilitating pilgrimage.
As India continues to develop its infrastructure, the Pamban Railway Bridge remains an important symbol of engineering excellence and a testament to human ingenuity. This bridge has been listed as one of the "Most Impressive Railway Bridges in the World" by the Indian Railways and featured in various renowned national and international engineering and architecture publications.
Steps to modernize this bridge to increase its height to accommodate larger commercial ships with a vertical lift span of 72 meters will pave the way for better mobility and commercial connectivity. Besides, its integration with the proposed Rameswaram-Dhanushkodi railway line may prove to be a game changer for the entire southern region. Undoubtedly, it reflects the Indian ambition to become Viksit Bharat by the year 2047.
