Council has been planning the upgrade of Youngs Crossing Road at Joyner where it crosses the North Pine River to improve its flood immunity, safety and vehicle carrying capacity given forecast growth in population, development and traffic volumes.
This important road project has a funding commitment of $51.6 million from the Australian Government, as well as a further $15 million from the Queensland Government.
With the Youngs Crossing Road transport corridor being a critical link to the South East Queensland road network, this upgrade is one of the biggest road infrastructure projects to be delivered by Council and is crucial to transport services within our region.
The project spans more than one kilometre from Protheroe Road to Dayboro Road. The new river crossing involves construction of a bridge, approximately 200 metres in length, located to the west of the current road.
Status update
Work crews and equipment are starting to arrive at the site of the Youngs Crossing upgrade project.
Mayor Peter Flannery, Federal Member for Dickson Ali France, Labor Senator for Queensland Corinne Mulholland, Councillors Cath Tonks and Jim Moloney, principal contractor Seymour Whyte and design contractor HDR marked the milestone at a sod-turning ceremony at the site on Friday, 11 July.
City of Moreton Bay announced in May it had signed a contract with Seymour Whyte for $86 million for a significant portion of works on Youngs Crossing Road.
More information about construction staging, locations and anticipated durations will be shared on this page over coming months.

Project alignment and key benefits
Project alignment and key features
- Protheroe Road signalised intersection to increase safety and assist traffic flows.
- Access to Youngs Crossing Park will be maintained via a four-way signalised intersection.
- U-turn capability to assist Pony Club access via Youngs Crossing Road.
- Lookout platform.
- Existing Youngs Crossing will remain open to pedestrians/cyclists and link to Merv Ewart Reserve via new path under bridge.
- Fauna refuge poles, rope canopy connections and fauna rails to assist fauna movement.
- Retention of two large fig trees at the water hole.
- Koala exclusion fencing to restrict road access.
- Piers and piles designed to minimise hydraulic impacts to Sideling Creek, Pine Rivers Pony Club and Dayboro Road.
- New Pine Rivers Pony Club entry.
- Improved culvert crossing at Sideling Creek to enhance water and fish movement.
- With the new bridge running west of the existing roadway, construction work can largely occur offline in stages, minimising disruptions, alterations and temporary works.
- Extensive landscaping and tree planting along new alignment (areas shaded green).
- Upgrade to Dayboro Road intersection to a improve safety and traffic flow.

Upcoming works
Service relocations
The project requires the relocation of some essential utility services, including water, sewer, telecommunication and electricity.
Since February 2025, a contractor has been installing electrical conduits under the North Pine River, Sideling Creek and Youngs Crossing Road in preparation for the relocation of power infrastructure by Energex to suit the new road and bridge alignment.
Activities include:
- locating existing electrical infrastructure
- establishing temporary construction amenities
- clearing some vegetation situated within the relocation corridor
- excavation and boring
- installation of the new underground conduits
- reinstatement of disturbed areas.
For the safety of motorists, pedestrians and crews, the speed limit within the construction zone will be 40 kilometres per hour during work hours. Council asks that you observe the instructions of work crews and all signage, and plan any travel accordingly.

Minimising environmental impacts
The significance of koala populations and native flora and fauna in and around the project area are key considerations for Council and the community.
To achieve the best outcome, Council is working to reduce impacts as much as possible. Specialist environmental consultants have been engaged to assess the impacts and advise mitigation measures.
This project will affect some areas of environmental significance, mostly through the clearing of vegetation to accommodate the new bridge and its roadway. However, for every tree removed, 6 new trees will be planted strategically along the alignment and in surrounding areas to provide safer habitats, as well as enhanced corridors and connectivity for fauna.
Environmental impacts and cultural heritage assessments will be managed in line with Commonwealth and State legislation in addition to Council’s environment management framework.
Project funding
This important road project has a funding commitment of $51.6 million from the Australian Government, as well as a further $15 million from the Queensland Government.
The State Government is also investing $350,000 to progress planning for Dayboro Road. The Department of Transport and Main Roads (DTMR) is currently undertaking a study to develop a 20-year vision for the development of Dayboro Road between the Gympie Road and Youngs Crossing Road intersections.

Project background information
Youngs Crossing Road is an important north-south arterial road connecting the Moreton Bay Region with Brisbane City.
The road is used by approximately 20,000 vehicles every day, and traffic is forecast to increase to 22,500 vehicles by 2026 and 27,500 vehicles by 2036.
Council has been progressively upgrading sections of Youngs Crossing Road to four lanes to cater for this growth.
Council began preliminary planning and design work in late 2019 to upgrade the road where it crosses the North Pine River at Youngs Crossing.
Youngs Crossing Road has low flood immunity and has been forced to close following some rain events and water releases from North Pine Dam, causing delays, congestion on local roads and economic impacts.
In 2020 Council developed concept designs for two proposed upgrade options as part of the project’s early planning and design stage and sought community feedback on these options:
Option 1 – Youngs Crossing Road existing alignment
Option 2 – Andrew Petrie Drive alignment
Council received over 4,300 responses, with 66 per cent of respondents supporting Option 1.
Council made a formal decision to select the Youngs Crossing Road alignment at the General Meeting held on the 12 November 2020(PDF, 4MB).
