Project overview

With Logan’s population set to continue growing, we are investing in our roads to ensure they are fit for purpose, now and well into the future.

As a vital east-west link, this upgrade to Chambers Flat Road will improve safety, flood resilience and travel conditions for everyday users.

We are upgrading 3.8 kilometres of road from Mount Lindesay Highway, Munruben to just north of Kings Way, Chambers Flat.

Traffic is expected to increase significantly over the next 20 years due to residential and business growth. The upgrade will allow Chambers Flat Road to safely accommodate future traffic demands from local and adjoining development areas.

Chambers Flat Road currently carries approximately 19,000 vehicles a day.

This figure is expected to rise by 47 per cent to approximately 28,000 vehicles a day.

Project features

The project will:

• widen the road with 3.5m-wide traffic lanes and 3m-wide sealed shoulders (asphalted to provide a safer, smoother road with reduced tyre noise impacts for residents)
• reinstate 80km/h speed limit once the road is commissioned
• build a new bridge over Norris Creek (up to 8m higher than the existing culvert)
• improve the intersections at Kings Way and Greenvale Road to include dedicated turning lanes from Chambers Flat Road
• upgrade Grevillea Road and Norris Creek Road intersections
• improve sight lines at bends and crests
• install new stormwater drainage
• install a variety of wildlife devices including fauna fencing, escape poles, culvert crossings and nesting boxes.

Norris Creek Bridge

Modelling was undertaken during design of the new Norris Creek bridge for both local storm and regional flood events, to ensure future flooding impacts are mitigated.

According to the modelling, during a 1-in-100-year Norris Creek storm event, water levels are expected to peak below the bridge. During a 1-in-20-year Logan River flood event, backwater would push up Norris Creek from Logan River, with water levels expected to peak under the bridge road level. A more severe flood would overtop the bridge, according to the studies.

With the existing culverts removed and the bridge and associated earthworks constructed, modelling indicates no adverse impacts during events up to and including the 1-in-100-year storm and regional flood.

Project benefits

The upgraded road will help to:

• improve safety as traffic increases
• improve sight lines for crests and curves
• unlock local bottlenecks for more reliable travel times
• improve flood resilience
• build a well-managed road network to improve access and economic opportunity.

Project impacts

Our contractor, SEE Civil Pty Ltd, is making every effort to minimise disruption. Given the nature of works, some temporary construction impacts can be expected:

• increased levels of noise, dust, and vibration, particularly at Norris Creek bridge site
• delays while bridge beams and decking units are transported to site and lifted into place
• temporary lane switches
• property fencing works
• continued driveway and road drainage works
• temporary side track at Greendale Road intersection upgrade works
• changed traffic conditions, including diversions, traffic congestion and travel delays.

Road users are advised to plan their journey and allow extra travel time. We thank you for your cooperation and patience as we work to provide a safer, more resilient and reliable road network.

We will continue to work with SEE Civil Pty Ltd to reduce these impacts as much as practical by:

• suppressing dust on site during the works (via water truck or dust suppression agent)
• directing lighting away from properties as much as possible
• reducing noise as much as possible (although some activities will make it unavoidable at times)
• undertaking noise monitoring.

Through traffic restrictions

The eastbound lane was closed at the start of the project and through traffic is diverted until mid-2024. Please see the Detour map (PDF 195 KB). 

The eastbound and westbound lanes of Chambers Flat Road will be opened progressively from Riverina Court and Kings Way as the road is commissioned.

Local traffic

The westbound lane has remained open with reduced speed limits in place to provide residents access to the Mount Lindesay Highway and Crowson Lane.

Heavy Vehicles

Due to the size and scope of the works, our contractor, SEE Civil Pty Ltd, established their site compound on Council-owned property at 296-308 Teviot Road, North Maclean for the duration of the project.

You may see materials relating to drainage and bridge supports in addition to prefabricated structures and temporary stockpiling of earth at this site.

We have asked our contractor to avoid hauling materials with trucks along Greenbank Road.

Please view the preferred routes for heavy vehicles (PDF 295 KB).

Increased noise and dust will continue to occur as these vehicles travel along these approved routes until they are no longer required for the project.
