Sinnamon Road Ramp Closures Start as Centenary Bridge Upgrade Moves to New Stage

The Transport and Main Roads Department (TMR) is preparing to shift Centenary Motorway southbound traffic onto the new bridge as part of the ongoing Centenary Bridge Upgrade, and that means temporary closures of the Sinnamon Road on and off ramps are imminent.

The closures, rolling out across two separate stages in March 2026, are necessary to allow southbound traffic to be moved onto the new bridge.

Member for Inala Jess Pugh announced the upcoming disruptions this week, urging motorists to plan their routes in advance and allow extra travel time.

The closures are being delivered in two distinct stages, each targeting a different ramp and affecting traffic in different directions.

Stage 1 — Northbound on-ramp closure

From 8pm Friday 6 March to 5am Monday 9 March 2026, the Sinnamon Road northbound on-ramp will be closed. Motorists will be detoured via the Mount Ommaney interchange at Dandenong Road. The southbound off-ramp remains open throughout this stage. Reduced speeds and intermittent overnight lane closures on the motorway are also scheduled, with traffic control and signage in place for the duration.

Stage 2 — Southbound off-ramp closure

From 8pm Sunday 15 March to 5am Friday 20 March 2026, the Sinnamon Road southbound off-ramp will be closed. Traffic will be diverted to the Seventeen Mile Rocks Road off-ramp. The northbound on-ramp will be open during this stage.

TMR has confirmed that traffic control will be in place and signage will guide motorists throughout both stages.

About the Centenary Bridge Upgrade

The ramp closures are part of a broader infrastructure project underway on the Centenary Motorway corridor. According to TMR, the Centenary Bridge Upgrade includes the construction of a new three-lane northbound bridge, which will also improve the on-ramp from Jindalee. Modifications to the existing structure will create a dedicated southbound bridge, also with three lanes, improving the off-ramp to Jindalee and incorporating active transport facilities.

The additional lanes across the bridges will enable further upgrades to the motorway in the future, according to TMR. Those future works form part of the broader Centenary Motorway Upgrade project — a program aimed at delivering greater capacity, efficiency, and travel-time reliability between Brisbane’s CBD and the western suburbs, between local destinations, and along the entire Centenary Motorway corridor.

Major Construction Milestone for Centenary Bridge Upgrade in Jindalee

The Centenary Bridge Upgrade in Jindalee has reached a significant construction milestone. Installation of the first concrete girders has begun.

Project Background and Scope

The Centenary Bridge Upgrade spans the Brisbane River between Sinnamon Road, Jindalee, and Kenmore Road. It forms part of a staged improvement program along the Centenary Motorway. It is designed to meet long-term transport demands between Brisbane’s western suburbs and the CBD. A construction contract was awarded in December 2022, and works are currently underway.

The project involves constructing a new three-lane northbound bridge. This will convert the existing bridge into three southbound lanes. A key feature of the upgrade includes enhanced active transport facilities, with a dedicated path for pedestrians and cyclists linking to the Western Freeway Bikeway. The Jindalee Skate Park is being retained within the project footprint.

Key Technical Milestone Achieved

A major development has been marked by the installation of the first concrete girders on the new northbound structure. These girders, measuring between 34 and 48 metres in length, are being produced on-site at a precast facility just north of Sinnamon Road. A total of 30 girders will be manufactured as part of the bridge construction.

This step signals visible progress in the build, which aims to reduce congestion, improve safety, and increase capacity on a major arterial route.

Funding and Investment

The project is jointly funded by the State and the Australian Government. As of the December 2023 update, the total investment stands at $298.5 million. This includes $159.25 million from the Queensland Government and $139.25 million from the Australian Government (Investment ID 669801).

Public Opinion and Community Sentiment

Public responses to the milestone have been mixed. Some residents expressed frustration over the perceived slow pace of progress, with several noting that the upgrade merely shifts the existing bottleneck further along the motorway. Others raised concerns about the timing and extent of shared path improvements, particularly regarding pedestrian and cyclist access during construction.

Despite criticism, some members of the public acknowledged the anticipated benefits of increased bridge capacity and active transport improvements, particularly in the lead-up to Brisbane’s future growth needs.

Next Steps and Broader Implications

The bridge upgrade forms part of broader planning studies examining possible staged improvements along the Centenary Motorway corridor, including sections beyond Jindalee.

Work will continue on completing the remaining girders, installing active transport links, and rehabilitating the existing bridge for southbound use. Updates on construction staging are anticipated in future communications.

Construction Contract Awarded: Centenary Bridge Upgrade Now a Step Closer

The Centenary Bridge Upgrade is now a step closer with the awarding of the construction contract in late December 2022. Once delivered, the upgrade will improve safety, increase capacity, reduce peak hour congestion and less travel time between the CBD and western suburbs, between local destinations, and along the Centenary Motorway.

The contract was awarded to Georgiou Group and BMD Constructions, as a joint venture, Premier and Minister for the Olympics and Paralympics, and Member for Inala Annastacia Palaszczuk announced last 27 December 2022.

“This upgrade will see a new three lane Centenary Bridge built in Jindalee, as well as an upgrade of the existing bridge, meaning you’ll get home safer and sooner,” the Premier said.

“More than 85,000 cars use this bridge daily, and that number will increase.

“This is an important step towards busting congestion through our growing region.”

State Member for Mount Ommaney Jess Pugh said that previous tender submissions “came in low, and another even promised to build two new bridges with the funding.” He added that both of the proposed options had been thoroughly explored.

“After consideration, we saw that these tender submissions could not deliver on what was promised. I’m pleased we can now move forward with a reliable, Queensland based joint venture, with over 40 years experience,” he said.

“The project will double capacity across the river, as well as improve access to Amazon Place Park while preserving the much-loved Jindalee Skate Park.

“We know how important it is to include safe options for cyclists and footpath users, especially those who travel on two wheels, in a wheelchair, mobility device, or pushing a pram.”

The Centenary Bridge accommodates more than 85,000 vehicles a day. Current traffic modelling shows that the volume of vehicles crossing the bridge will swell to around 152,000 per day by 2036.

The Centenary Bridge Upgrade in Jindalee will include a new 3-lane northbound bridge and the rehabilitation of the existing bridges to create three southbound lanes along with an upgrade of active transport facilities with improved connection to the Western Freeway Bikeway and local destinations and the retention of the Jindalee Skate Park.

The Federal and Queensland Governments are jointly funding this $298.5 million project.

Centenary Bridge Duplication Funding Secured

Construction of a duplicate Centenary bridge, located in Jindalee, may now proceed as State has matched funds given by the Federal government for the Centenary Bridge upgrade project.

In early October 2020, it was announced that key infrastructure projects across Queensland will receive a total of $1.3 billion in federal funding. Of that amount, $112 million will be allocated for the Centenary Bridge Upgrade.

The day before the release of the 2020-21 Federal Budgeted, Premier Annastacia Palaszczuk said that the state government will match the amount coming from the federal government. Hence, the funding for the construction of a second Centenary Bridge at Jindalee has been locked in.

The Premier said that while construction sites came to a halt across the world due to the pandemic, work hasn’t stopped in Queensland, “because of our strong response to managing the health crisis.”

She added that since November, the state government has announced more than $4.8 billion in new and accelerated joint funding for projects that will allow people to get “into jobs quickly.”

“We have done the work to get the new Centenary Bridge project ready to build and we’ll start work on it next year, supporting hundreds more jobs,” the Premier said.

“Our infrastructure guarantee is backing Queensland jobs and driving demand for tradies across the state at a time when they’re needed most.”

Construction of the new bridge is set to commence in 2021. The project involves the construction of a new, three-lane, northbound bridge built to the west of the existing bridge. There will also be a reconfiguration of the existing bridge that will provide southbound lanes, as well as improvement of active transport for both pedestrians and bike riders.

The State and Federal Government will split the total $224 million construction budget while another $20 million was already provided by the State Government for the project’s planning and design.
