Kalutara Bridge, sitting across Kalu Ganga in Kalutara, is a historically significant structure which was first opened for road traffic in August 1877. This unique bridge consists of two spans, each measuring 194.4m, separated by an island in the middle of the river. Serving as a vital link between the Western and Southern borders of the country, the bridge was designed and constructed under the pioneering direction of J. R. Mosse, Director of the Public Works Department (PWD). During the early 1900s, it stood as the largest bridge on the island and was considered Sri Lanka’s first concrete bridge. Today, the site features twin railway bridges alongside a road bridge, offering scenic views of the three-story Kalutara temple, a prominent Buddhist landmark.
