DEC 2019Rehabilitation work to wrap up for 2019

The first stage of essential rehabilitation work on Windang Bridge to help protect the bridge piers from scour will soon draw to a close. Work started in August and so far approximately 7300 tonnes of rock has been placed around the bridge piers to help prevent further scour. Work to date has been a success in reducing scour and will extend the life of the bridge, ensuring it remains safe and operational.

Work will continue up until Thursday 19 December at which point the project will be packed up and the area returned to the community. We remind the public that jumping into the water from Windang Bridge is prohibited. Temporary fencing will remain in place above the locations where rocks have been placed for safety.

A decision will be made in early 2020 as to whether further rehabilitation work is required following continued bridge monitoring over the coming months.

We thank the community for their patience while we have carried out this essential work.

SEP 2019Rehabilitation work

The NSW Government is funding essential rehabilitation work to ensure the safe and reliable operation of the bridge.

Transport for NSW will carry out essential rehabilitation which will involve placing rocks from a barge around the bridge piers to help prevent further scour (erosion), improve safety and reduce ongoing maintenance.

This work will ensure the bridge is safe and operational for motorists, and extend the life of the bridge. Work will be carried out at the north end of Windang Bridge and take around three months to complete.

From 16 September a second rock stockpile will be established at the western side of the bridge, located on Judbooley Parade. This will allow rock placement to be carried out more efficiently, with two barges operating on the western side of the bridge.

One barge will be holding rock from the stockpile while a second barge will place rock using an excavator around bridge piers.

While this stockpile site is in operation, there will be some increased heavy vehicle activity on Oakland Avenue and Boronia Avenue and a short section of the shared path will be impacted.

A temporary shared path will be in place at the northern end of the bridge.

Pedestrians and cyclists are advised to keep to the new temporary shared path when walking around and under the bridge and should follow the direction of signage.

Heavy vehicle activity will continue on Fern Street, Windang to carry out this essential work which involves the placement of rocks from a barge around the bridge piers.

A site office and rock stockpile has been established on the eastern side of Windang Bridge. The site office is located in the southern end of the carpark off Fern Street occupying around 14 car spaces.

Additional truck movements, barge and excavators will be required in Fern Street throughout the project, to allow for the delivery of rock stockpiles to the temporary site offices.

Rock placement will be carried out between 7am and 5pm from Monday to Friday and 7am to 1pm on Saturday. No work will be carried out on Sundays and public holidays.

Bridge monitoring

Inspection and monitoring work will continue through the project from the underside of Windang Bridge to help carry out rehabilitation work.

The southbound slow lane and shared footpath will be closed for work on Wednesdays until the end of the project between 7.30am and 3pm, weather permitting.

The shared path will remain open at all times for pedestrians and cyclists during this work.

Motorists are advised of changed conditions and should allow an additional five minutes travel time and follow the directions of traffic control.

Transport for NSW apologise for any inconvenience and will keep the community advised of changed conditions to the lake including limited access on waterways around and underneath the bridge and should avoid fishing around the work site.

Thank you for your patience while we carry out this essential rehabilitation work.

Project information

The bridge crosses Lake Illawarra and carries two lanes of southbound and two lanes of northbound traffic.

More than 40,000 road vehicles use the 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.

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 299.60 metres long and 20.80 metres wide carrying four lanes of traffic and shared paths for pedestrians and cyclists both sides of the deck.
