Jabiru Island bridge duplication has moved into active design and site investigation.
Queensland has moved the Hope Island Road bridges duplication at Jabiru Island beyond a planning announcement and into an active design phase, with surveyors now on site and geotechnical and utility investigations underway.
The published scope is substantial: two new bridges will duplicate the existing 236-metre Coombabah Creek Bridge and 194-metre flood-relief channel bridge, completing the missing four-lane link on Hope Island Road. The project also includes a new signalised four-lane intersection, an off-road shared path on the new bridges, and upgraded street and navigational lighting.
For contractors and suppliers, the current signal is a project-definition workfront rather than a released main-construction market. The Queensland Government says site investigations will continue into early 2027; the sources reviewed do not yet announce a main-works contractor, construction start date, project budget or supplier packages.
Design and site investigations are now underway at Jabiru Island
The Queensland Government announced on 6 October 2026 that the Hope Island Road bridges duplication at Jabiru Island had entered the design phase. Surveyors are collecting information on site, and the government says geotechnical and utility investigations will continue into early 2027.
That is a meaningful stage change from the Gold Coast Transport Plan released in August, which identified the bridge duplication as part of the region’s future transport program. The live activity is now design support and field investigation rather than only policy-level commitment.
The immediate workfront is therefore technical and preparatory. Survey data, ground information and utility information will feed the project design and help define how the two new bridge structures, road tie-ins, intersection changes, active-transport infrastructure and lighting can be delivered.
The scope completes the missing four-lane link on Hope Island Road
Two new bridges, intersection works, active transport and lighting
The Department of Transport and Main Roads describes two new bridges at Jabiru Island: a duplication of the existing 236-metre Coombabah Creek Bridge and a duplication of the 194-metre flood-relief channel bridge.
The new structures are intended to remove the two-lane bottleneck between existing four-lane sections of Hope Island Road. The department also lists a new signalised four-lane intersection to improve access to Jabiru Island Park and boat-ramp facilities.
Active transport is part of the published scope. An off-road shared path is planned on the new bridges, while upgraded street lighting and navigational lighting are also included. These elements make the future delivery package broader than bridge superstructures alone.
The project forms part of the Queensland Government’s Gold Coast Transport Plan, which is intended to increase network capacity and support a growing northern Gold Coast. The government specifically points to congestion around the Crescent Avenue intersection as one of the problems the duplication is intended to address.
The current workfront is surveying, geotechnical investigation and utility investigation
Field information is being collected to support design
The government says surveyors are already on site. It has also identified geotechnical works and utility investigations as part of the investigation program continuing into early 2027.
For the market, this is an important distinction. Design-stage activity can create specialist work across surveying, geotechnical investigation, utilities and engineering services, but the public sources reviewed do not identify which firms hold those scopes. BBI therefore does not attribute current packages beyond the information formally released.
The investigation period also means major construction sequencing is still ahead. Bridge foundations, traffic staging, utility interfaces, marine or waterway constraints, road tie-ins and temporary works may become important parts of detailed delivery planning, but those package boundaries should not be treated as confirmed until TMR publishes them.
Commercially, the project is visible before the main-works market is defined
Future civil and bridge capability is relevant, but no package should be called live yet
The physical scope points toward a future market across bridge construction, roadworks, intersections, active transport, lighting and related civil interfaces. That is useful for capability planning, particularly for businesses active in South East Queensland transport infrastructure.
However, project scope is not the same as a procurement release. The sources reviewed do not identify a main-works delivery model, tender date, construction contract value, awarded principal contractor or supplier packages. Those items remain watch points rather than current opportunities.
Interested contractors should monitor official TMR procurement channels and project updates rather than infer live work from the design milestone alone. This is especially important because early technical investigations can be undertaken under existing arrangements that are not the same as the future construction package.
What BBI is watching next
The first near-term marker is completion of the current survey, geotechnical and utility investigation program and evidence that the bridge and corridor design is advancing toward a procurement-ready definition.
After that, the most commercially important disclosures will be the project’s funding and delivery arrangements, any announced procurement model, the identity of a principal construction contractor or shortlisted teams, and an executable construction program.
Construction timing is particularly important. The government has said the investigations continue into early 2027, but the current primary material reviewed for this article does not give a date for main construction to begin. BBI will treat any future tender, award or construction-start announcement as a separate stage change.
For broader Gold Coast infrastructure context, the bridge duplication sits alongside other elements of the Gold Coast Transport Plan. BBI has previously covered the region’s transport pipeline, including Gold Coast Light Rail Stage 3.
