Windang Bridge is a vital link between Wollongong and Shellharbour carrying approximately 40,000 vehicles per day.
MAR 2020Work on Windang Bridge to continue
Stage two of planned work to protect Windang Bridge over Lake Illawarra will be carried out to help keep the bridge safe and operational for all road users.More information
Rocks will be placed around the bridge piers to prevent erosion, reduce ongoing maintenance and strengthen the structure.
Stage one of work was carried out in 2019 and included 7300 tonnes of rock placed around the bridge piers, which has already resulted in a reduction of erosion.
Stage two will be carried out at the north end of Windang Bridge and include 1800 tonnes of rock being placed, taking about three months to complete, weather permitting.
Work will be carried out on the waterway and in Fern Street from Wednesday 18 March, between 7am and 5pm on weekdays and from 7am to 1pm on Saturdays. No work will be carried out on Sundays and public holidays.
A site compound will be established on the eastern side of Windang Bridge in the carpark off Fern Street, occupying around 14 parking spaces.
During the rock placement activities there will be no impact to traffic on the bridge or to the shared paths for bicycles and pedestrians.
Additional heavy vehicle movements will take place in Fern Street, to allow for the delivery of rock stockpiles to the site compound.
Bridge monitoring and inspections will be carried out for one weekday each month during this project. One southbound lane will be closed and a 40 km/h reduced speed limit will be in place from 9am to midday during this work.
Transport for NSW apologises for any inconvenience and will keep the community updated as work progresses. The community is also advised to avoid fishing and other recreation activities around work sites.

Windang Bridge monitoring
The bridge crosses Lake Illawarra and features two lanes of southbound and two lanes of northbound traffic, as well as two shared paths on either side of the bridge.
More than 40,000 vehicles use Windang Bridge each day. The pedestrian and cycleway paths provide both recreational and commuting access.
An increase in the amount of scour (erosion) at the northern end of Windang Bridge in Lake Illawarra has been observed over the last two to three years.
Underwater inspections have been carried out in 2019 and revealed some significant scouring around Piers four and five.
Stage one of work was carried out from August to December 2019, approximately 7300 tonnes of rock was placed around piers to help prevent scour.
Live monitoring equipment and strain gauges have been installed on Windang Bridge to help monitor bridge conditions and help us plan for future bridge remediation work.
Remediation and maintenance work will be carried out on Windang Bridge around the affected piers to help prevent further scour.
Longer term plans to manage the effects of scour on the bridge piles will be developed over the next 12 to 18 months.
Windang Bridge was constructed circa 1963 and widened later in 1974 from the downstream side. The Bridge comprises 33 spans and is about 299 metres long and 20 metres wide carrying four lanes of traffic and shared paths for pedestrians and cyclists both sides of the deck.
