MAY 2020Rehabilitation work on Windang Bridge completed

Stage two of work to protect Windang Bridge over Lake Illawarra has been completed to help keep the bridge safe and operational for all road users.

Rocks have been 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 was carried out between March and May 2020 at the north end of Windang Bridge and included 1800 tonnes of rock being placed around the bridge piers.

Transport for NSW reminds the community that fishing from the bridge is prohibited. For more information, read the March 2020 Frequently Asked Questions (PDF, 96.5Kb).

Project information

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, with about 7300 tonnes of rock placed around piers to help prevent scour.

Stage two was carried out between March and May 2020, with about 1800 tonnes of rock placed about bridge piers.

Bridge monitoring and inspections will be carried out on one weekday every three months. 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.

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.
