Statement of significance:

The Parramatta River Underbridge (John Whitton Bridge) is of local significance as it is the first bridge on the New South Wales rail network constructed using welded steel box girders, and remains a rare example of this construction type. The bridge commemorates John Whitton, the "Father of NSW Railways". Its location adjacent to the original 1886 lattice girder bridge (Meadowbank Bridge) gives the bridge greater aesthetic quality as a landmark structure and demonstrates the evolution in bridge design over the intervening period.

The adjacent former rail bridge is no longer owned by RailCorp and is listed on the State Heritage Register.

History

Historical notes: The first section of the Main North Line was built from the port of Newcastle to Victoria Street, Maitland in 1857 and extended to Singleton in 1863, Muswellbrook and Murrurundi in 1872, Werris Creek and west Tamworth in 1878, Armidale in 1883 and Wallangarra, Queensland in 1888. The Sydney to Newcastle section was started significantly later due to the difficult topography, including the need to cross the Hawkesbury River. The line was opened to Hornsby in 1886 and Hawkesbury River station at Brooklyn in 1887. The line also opened from Newcastle to Gosford in 1887. The Hawkesbury River bridge and the line to Gosford were opened in 1889.

The original bridge across the Parramatta River was the Meadowbank Bridge, a lattice girder bridge designed by John Whitton, Engineer-in-Chief of the NSW Railways from 1856 - 1890. The bridge was constructed in 1886 as part of the original infrastructure for the Main North Line.

Electric arc welding was developed overseas in the 1920s, and first used in NSW for the strengthening of the Hawkesbury River Bridge, becoming an established method for the repair and strengthening of existing steel bridges. Welded steel was used for the construction of buildings, power stations and light structural framework, but was slow in being adopted for rail use due to lingering fears of the dynamic loading of rail use producing fatigue failure in bridges.

The railway limitations of the old Meadowbank Bridge had been recognised prior to World War II so plans were drawn up for its replacement as part of the quadruplication of the Main North Line. The concrete piers were completed on the eve of the 1952 recession and work was suspended for 20 years. By 1972 when a new bridge was truly a necessity, the new technology of lightweight steel, welded box girders offered a much cheaper and more elegant solution than the heavy, visually dominant trusses. It was now possible to accommodate quadruplication of the line on the existing concrete piers, which were widened by a concrete cap to suit 4 tracks, but only two single track, steel box girder bridges were built and came into service in 1980. These make up the John Whitton Bridge. The old bridge remains the Meadowbank Bridge, but is no longer in rail ownership.

Assessment of significance

SHR Criteria b)
[Associative significance]
The Parramatta River Underbridge (John Whitton Bridge) has historical associative significance as it is commemorates John Whitton, the "Father of NSW Railways"
SHR Criteria c)
[Aesthetic significance]
The Bridge has aesthetic significance as a highly visible landmark structure across the Parramatta River. The John Whitton Bridge has technical significance as the first use of welded steel box girders on the New South Wales railway network.
SHR Criteria e)
[Research potential]
The John Whitton Bridge was constructed in 1980, using the existing concrete piers from 1952, adjacent to the original 1886 truss bridge and displays the evolution of rail bridge construction between 1886 and 1980.
SHR Criteria f)
[Rarity]
The John Whitton Bridge remains a rare example of a welded steel box girder bridge.
Integrity/Intactness: The bridge is of high integrity, retaining its original fabric in a good condition.
