[3] In 1815, government architect Francis Greenway, in a report to Governor Macquarie, proposed the building of a bridge from Dawes Point at the city's edge to the northern shore.

This location enabled passengers from the North Shore to transfer directly from steam trains to ferries to reach Circular Quay.

[3] In 1915, to enable a start on the construction of the Sydney Harbour Bridge between Milsons Point and Dawes Point, the Government instructed the Railway Commissioners to vacate the station and a new four platform, station was constructed at the site of the boundary fence between the present-day Luna Park and Lavender Bay Sidings.

Tenders were invited in 1923 in accordance with general plans and specification prepared by Dr John Bradfield, Chief Engineer, Sydney Harbour Bridge and Railway Construction.

The tender of Dorman Long & Co Ltd, of Middlesbrough, England, for an arch bridge was accepted, the design being substantially in accordance with one of Dr Bradfield's proposals.

The detailed design was carried out by the contractor's consulting engineer, Sir Ralph Freeman, and the fabrication and construction were under the direct charge of Mr Lawrence Ennis, a director of the firm.

The northern approaches were built using spoil from the excavation of the North Sydney station site to build a ramp up to the main bridge level.

The railway decking had advanced as far as Milsons Point, tracks had begun to be laid and the transoms delivered for installation.

The western platforms were connected to the North Shore line with the eastern pair used for a tramway service between Wynyard and the northern suburbs.

The tramway and the associated platforms at Milsons Point were removed in 1958 as part of the conversions of lanes 7 and 8 of the Harbour Bridge to become the Cahill Expressway.

[8][9] The station was upgraded and received a lift connecting the platform and underneath concourse at some point between January 1992 and September 1998.

[3] The south end of the Station group area includes the Burton Street Under-bridge 4.340 kilometres (2.697 mi), a high arch reinforced concrete underbridge constructed as part of the northern approaches to the Sydney Harbour Bridge and a similar design as the neighbouring Fitzroy Street Underbridge 4.250 kilometres (2.641 mi).

These underbridges are dealt with as individual items on separate listings[13][3] The station building, platform and under-bridge are in good condition.

The form and detail of the subway and tunnels in particular are significant as part of the overall design and specifications for the bridge as set down by Chief Engineer JJC Bradfield.
