Kalurghat Bridge, Railway bridge in Chittagong, Bangladesh

Kalurghat Bridge is a 239-metre railway bridge over the Karnaphuli River, built in 1930 with two abutments, six brick pillars, twelve steel pillars and nineteen spans. Its steel structure includes a 45.72-metre girder and twelve 30.48-metre under-slung spans. A six-foot-wide walkway was added to the deck for pedestrians.

The bridge was built in 1930 by British engineers and was originally designed to serve rail traffic between two stations. It was part of the infrastructure developed during the colonial period.

The Kalurghat Betar Kendra, a radio station that played a historic role in the 1971 Liberation War, is actually located near Bahaddarhat, not at the bridge; it took the Kalurghat name because the area was already widely known. The bridge itself is remembered for the fighting between the Mukti Bahini and the Pakistan Armed Forces for control of its western and northern banks.

The bridge has strict weight limits and is crossed at very low speeds for safety reasons. Visitors should prepare for uneven conditions and confined spaces when using it.

The bridge deck was widened with a 6-foot dedicated walkway for pedestrians, giving local residents all-weather, round-the-clock safe passage across the Karnaphuli. The Dhaka–Cox's Bazar direct train link required strengthening work assessed by engineer A F M Saiful Amin of BUET.
