Lennox Bridge, Parramatta, 1836-1839

David Lennox was born in Ayr, Scotland, and was trained as a stonemason. He was experienced in bridge 
building under the famous engineer Thomas Telford having worked on a stone bridge across the Severn in 
Gloucester and the Menai suspension bridge in north-west Wales. After the death of his wife, he sought 
employment in the colony arriving as an unassisted migrant in 1832. His talents were soon recognised and he 
was appointed as Superintendent of Bridges; became the first skilled bridge builder on the mainland. Any 
doubts about his ability were dispelled after his design and construction of a horseshoe shaped bridge at 
Lapstone (1833) and the 110 feet clear span bridge at Lansdowne over Prospect Creek (1834-1836).[55]

Lennox prepared preliminary designs for the bridge at Parramatta for Surveyor General Thomas Mitchell 
to whom he was responsible. Ambrose Hallan, the recently appointed Colonial Architect, countered with 
a proposal for a prefabricated iron bridge be imported from England.[56]  Fortunately for Parramatta, 
Governor Bourke, finding Hallan's lack of ability as an architect intolerable, interceded and requested 
a plan for 'an ornate bridge'.[57]  Mitchell's assistant, Captain Perry, entered the fray with a plan shortening 
the arch from 90 feet to 60 feet. Lennox dismissed this plan claiming correctly that such a narrow spanned 
arch would restrict flood waters. Midst the inter-departmental controversy that existed apart from the 
bridge plans, Lennox simply went ahead, and adapted the timber centering used on the Lansdowne project, 
declaring that as he had done so, he did not intend to alter his design.

All opposition collapsed and in May 1836 when Bourke, whose patience had been taxed over the whole 
proceedings, approved the Lennox plans and the bridge work was commenced on 22 October 
1836.[58]  In July, Lennox applied for stonemasons and later arranged for the supply of lime and cartage 
of quarried stone. The governor laid the foundation stone on 23 November, 1836.[59]  Progress was 
slow because of labour problems but by September 1838 one side was open to limited traffic and it was 
completed in the following year at a final cost of £1,797.

The structure may be described as a sandstone bridge with a single semi elliptical arch of 90 feet in length 
and 30 feet wide. Even though the approaches show all the softly graded curves of his earlier bridges, 
Morton Herman described the main arch perhaps as 'coarse and heavy'.[60]  If not as elegant as 
some of his other designs, it was nonetheless a valuable and worthy addition to the Georgian architecture 
of the town. The bridge remained nameless until 1867 when a motion before the Parramatta District 
Council proposed that it be named after the current governor, Sir William Denison (1855-1861) but it 
lapsed. Alderman Birmingham then proposed the name Lennox Bridge and the motion was passed.

John McClymont's article written in 1994 also pointed out how the structure of the bridge had been altered 
over the years. As early as 1802 there was a stone bridge at this location on Church Street but by the 
early 1830s it was in an 'insecure state', and around 1833 Lennox started planning to replace it with the 
what is now known as the 'Lennox Bridge'. In 1885-86 the Department of Public Works removed 
the wall on the upstream side of the bridge to widen it, and put up the present railing at the same 
time.  In 1912 it was widened for a tramway [to Castle Hill] and in 1930 the Sydney Morning Herald 
reported that there was a proposal to demolish the bridge. 

This 1930 article also mentions how the passage of time had worn away the words "Lennox Bridge" on the
 inside of the parapet wall on the downstream side of the bridge.
