Nehru Setu

Nehru Setu is a railway bridge spanning the Son River, connecting Dehri-on-Son with Son Nagar across a length of more than 3,000 meters. The structure uses steel girders supported by stone pillars and carries the Grand Chord railway line that links Kolkata and Delhi.

The bridge opened in 1900 and was initially the longest in India until another bridge surpassed it more than a century later. It was built during the period when railways became the backbone of India's transportation system.

The bridge holds a significant place in India's railway heritage, representing how engineering transformed regional connections during the colonial era. Today, travelers crossing it experience a piece of that historical transportation network firsthand.

The bridge is best viewed from a train crossing it, as it functions as a railway viaduct not accessible to pedestrians. For ground-level views, the riverbanks nearby offer good vantage points to see the structure and its stone supports.

The bridge is composed of 93 separate spans, each precisely engineered and connected across the wide river. Most travelers don't notice the careful repetition of these sections or the fact that this structure was completed without modern machinery.
