History

ReplacesVehicular punt between Lugarno and Illawong

The first bridge opened on 7 September 1973 and although the deck was built wide enough to accommodate three lanes of traffic, carried one lane of traffic in each direction. In 1980 the lane arrangements on the bridge were changed to provide a third lane, and a tidal-flow traffic management system was introduced, with two lanes northbound in the morning and two lanes southbound in the evenings.

When the first bridge was built, a second set of piles and abutments was built a few metres downstream, allowing for future duplication. The second bridge was opened for southbound traffic on 22 August 2008, leaving the first bridge for northbound use only.[2]

DescriptionEdit

There are two other road crossings over Georges River downstream of the Alfords Point Bridge: the Captain Cook Bridge, which opened in 1965 and Tom Uglys Bridge, which opened in 1929. Captain Cook Bridge connects Sans Souci to Taren Point. Tom Uglys Bridge connects Blakehurst to Sylvania.

HistoryEdit

The bridge was built as the last link in the Hornsby-Heathcote county road (although a number of route realignments followed), and serves a metropolitan function. Construction of the bridge allowed the decommissioning (in 1976) of Lugarno ferry, which had operated since 1843 on Surveyor-General Thomas Mitchell's line of the Illawarra Road. The ferry had operated between Lugarno and Illawong.[3]
