Hardinge Bridge (Bengali: হার্ডিঞ্জ ব্রিজ) is a steel railway bridge over the river Padma located at Paksey in western Bangladesh. It is named after Lord Hardinge, who was the Viceroy of India from 1910 to 1916. The bridge is 1.8 kilometres (1.1 mi) long.
The construction of a railway bridge over the Padma was proposed in 1889 by the Eastern Bengal Railway for easier communication between Calcutta and the then Eastern Bengal and Assam. In 1902, Sir FJE Spring prepared a report on the bridge. A technical committee reported that a bridge could be constructed at Sara crossing the lower Ganges between the Paksey and Bheramara Upazila stations on the broad gauge railway from Khulna to Parbatipur Upazila. The construction of the bridge started in 1910 and finished two years later. The bridge comprises 15 steel trusses. The main girders are modified "Petit" type.
The most difficult task of the operation was to prevent bank erosion and to make the river flow permanently under the bridge. For this, two guide banks of the "Bell-bund" type named after J. R. Bell were built on either side, each extending 910 metres (3,000 ft) upstream and 300 metres (1,000 ft) downstream from the bridge. The ends of the river banks were curved inward and heavily pitched with stone.
Hardinge Bridge was severely damaged during the Liberation War of Bangladesh of 1971. It happened on 13 December 1971, when the Indian Air Force plane bombed on the 4th guarder from the Paksey side. As the Pakistani army was on retreat towards Jessore (their last stronghold) Hardinge Bridge was strategically very important. The allied force damaged the bridge. The Japanese Government helped to reconstruct the bridge.
