Youngs Crossing upgrade, Joyner

Youngs Crossing Road closed due to flooding

Moreton Bay Regional Council is working to upgrade 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.

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 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 212 metre bridge, located to the west of the current road.

Recent activities

Since releasing the final concept design in July 2021, the project team has been progressing the detailed design for the new road and bridge, as well as the intersection at Dayboro Road.

Many on-site investigations and reviews have been carried out as part of this work, including land surveys, vegetation audits, soil and rock sampling, locating essential services such as water, sewerage, electrical, telecommunication as well as road and pavement assessments.

These site investigations, along with technical and road safety standards and feedback from the Department of Transport and Main Roads, have informed the design.

The project team has appreciated the community’s patience and understanding while this detailed design work has been done. 

The latest project layouts and features can now be viewed below.

Project alignment and key benefits

Project alignment and key features

  1. Protheroe Road signalised intersection to increase safety and assist traffic flows
  2. Access to Youngs Crossing Park will be maintained via a four-way signalised intersection (connection to the waterhole and existing car park to be finalised)
  3. U-turn capability to assist Pony Club access via Youngs Crossing Road
  4. Lookout platform
  5. Existing Youngs Crossing will remain open to pedestrians/cyclists and link to Merv Ewart Reserve via new path under bridge
  6. Consideration of fauna poles and rope canopies to assist fauna movement
  7. Opportunity to retain the two large fig trees at the waterhole
  8. Koala exclusion fencing to restrict road access
  9. Piers and piles designed to minimise hydraulic impacts to Sideling Creek, Pine Rivers Pony Club and Dayboro Road
  10. New Pine Rivers Pony Club entry
  11. Improved culvert crossing at Sideling Creek to enhance water and fish movement
  12. With the new bridge running west of the existing roadway, construction work can largely occur offline in stages, minimising disruptions, alterations and temporary works
  13. Extensive landscaping and tree planting along new alignment (areas shaded green)
  14. Upgrade to Dayboro Road intersection to a improve safety and traffic flow.

Project design

Next steps

With the road alignment and associated features now largely determined, the design process is now focused on producing the final detailed drawings, plans and project specifications required for construction.

The procurement process is underway with construction to start 2023.

The intention is to maintain traffic access along Youngs Crossing Road during construction.

Some early service relocation works such as sewer, water, communication and electrical services are currently being planned, prior to road and bridge construction activities.

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, five 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

Over $68 million has been committed to deliver the upgrade to this important regional transport corridor, with the Federal Government contributing $32.75 million. 

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 since 2010 has closed an average of 4.5 days a year following rain events and water releases from North Pine Dam, causing delays, congestion on local roads and economic impacts.

In 2021, weather events caused Youngs Crossing Road to close:

  • almost 2.5 days in March
  • 28 hours straight in April
  • 40 hours continuously from 30 November
  • 39 hours over another three days in December.

So far in 2022, the road has been closed for:

  • 18 hours on 1 January
  • 27 hours from 8 January
  • 14 hours on 21 January
  • 20 hours from 3 February
  • More than 13 days straight in March
  • More than 12 days in a row in May

In 2020 Council developed concept designs for two proposed upgrade options as part of the project’s early planning and design phase 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)
