Definition
The Hornibrook Bridge, also known as the Hornibrook Highway, was a timber‑supported road bridge that spanned Bramble Bay and Hays Inlet, linking the Redcliffe Peninsula with the mainland at Brighton, Queensland, Australia.
Overview
Construction of the bridge began in 1932 and it was officially opened on 13 March 1935. At the time of its completion, it was the longest bridge in Australia, measuring approximately 2.68 km (1.66 mi). The structure provided the first direct vehicular connection between Redcliffe and Brisbane, facilitating the development of the Redcliffe area. The bridge remained in service for vehicular traffic until 1975, when safety concerns led to its closure. Pedestrian access continued until the late 1980s, after which the bridge was progressively demolished and removed. Its function was superseded by the Houghton Highway (formerly the Redcliffe Bridge) and later the Ted Smout Memorial Bridge.
Etymology / Origin
The bridge was named after Sir Manuel Hornibrook, a prominent Australian civil engineer and founder of the construction firm Hornibrook Construction, which was awarded the contract for the project. The name reflects the common practice of honoring the principal contractor or engineer associated with major infrastructure works.
Characteristics
- Type: Timber‑deck, pile‑supported viaduct (trestle bridge).
- Length: Approximately 2.68 km (1.66 mi).
- Width: Initially a single vehicular lane with a footpath; later modified to accommodate two lanes of traffic.
- Materials: Primarily treated hardwood timber for piles and deck; concrete abutments at each end.
- Design Features: Repetitive timber bents spaced at regular intervals, allowing for relatively easy construction with the technology of the early 1930s. The bridge was raised sufficiently to permit small vessel navigation beneath, though its clearance limited larger maritime traffic.
- Operational History: Served as a toll bridge until the tolls were removed in 1940. After a period of declining structural integrity, heavy traffic loads led to the imposition of weight restrictions prior to its full closure to vehicles.
