First bridge
The original Como Railway Bridge opened on 25 December 1885 as part of the extension of the Illawarra railway line from Hurstville to Sutherland. It was a single track lattice truss bridge designed by John Whitton, the Chief Engineer of the New South Wales Government Railways. In 1890 the northern part of the Illawarra Line was duplicated, and the southern part towards Sutherland in 1891. This involved merging the two lines using points to a single line. In 1894 the tracks across the bridge were altered into a single gauntlet track on the bridge, which enabled trains to cross in either direction without points.[3]
Between 1935 and 1942, the Metropolitan Water Sewerage & Drainage Board built two 24 in (61 cm) diameter pipelines to pump water from the recently completed Woronora Dam to the reservoir at Penshurst. The pipeline was supported on new steel outriggers cantilevered from the main girders.[3][4] The ownership of the old bridge was transferred from the Railways Dept to Sydney Water.
Second bridge
To relieve the bottleneck, a new double track reinforced concrete bridge immediately to the west opened on 27 November 1972. The original bridge reopened as a cycleway on 15 December 1985.[3][5][6]
Heritage
Both bridges are listed on the various heritage registers of the state.
