Maldon is still an active rail location, having turnouts for freight trains bringing limestone to the cement works, and grain to the flour mill.

In 1983, the NSW government commenced construction of an electrified rail link between Maldon and Dombarton (near Wollongong), improving access for coal trains to Port Kembla.

[2] Maldon was also the site of 'Harvey's Crossing', one of two stone causeways over the Upper Nepean River on the Picton - Menangle Road.

Before finally determining upon the position at which the bridge was to be built, due consideration was given to the claims of both these sites: but it was decided that near Maldon presented advantages both from a traffic point of view and also in regard to economy construction.

The bridge has accordingly been erected at Harvey's Crossing on the road connecting Wilton with the Great Southern Railway at Maldon Station, and was opened by Mr. E. W. O'Sullivan, Minister for Public Works on March 12 [1903].

The main span is of 226 ft [feet] centres, carried by suspension rods from the cables, of which there are fourteen on either side of the bridge.

The cables have socketed end connections secured to steel girders in anchorages cut out of the solid rock and accessible for inspection.

The stiffening trusses are of steel, hinged at the towers and also at the centre, to allow for the rise and fall of the cables due to temperature changes.

[14] Local opinion largely opposed both these activities, fearing a negative impact on the immediate bushland environment due to increased visitor levels, and deterioration of the bridge itself.
