Last updated June 2026.
Council is upgrading Youngs Crossing Road in Joyner. This work focuses on the section where the road crosses the North Pine River. It is one of the City’s largest road projects and an important part of the South East Queensland road network. The project spans more than one kilometre, from Protheroe Road to Dayboro Road.
What’s happening now
Super-T girder deliveries
The Youngs Crossing Road bridge is being built using precast Super-T girders. There are 83 girders in total to support the base of the bridge deck. They are made off-site and transported by over-sized trucks escorted by pilot and police vehicles. Deliveries are expected to start from mid-July. They will occur intermittently over 5 weeks, weather and construction conditions permitting.
There will be some traffic impacts during transportation of the girders. To minimise these, delivery will occur at night during off-peak traffic periods, via Dayboro Road and Old Petrie Town. Residents of nearby properties will be informed of these deliveries closer to the scheduled dates.
The girders will be lifted into position during the day.
Concrete pours
There will be some Saturday or early morning concrete pours. These works will occur between 1 July and 23 July 2026 on the western side of Youngs Crossing Road. They are subject to weather and construction conditions.
Other construction works
Other construction activities and nightworks during July include:
- ongoing formwork and reinforcement of retaining walls
- underground services and pit installation on Protheroe Road and Dayboro Road
- intersection and traffic signals work on Youngs Crossing Road and Dayboro Road
- earthworks and rock placement around the new bridge
- vegetation management.

What to expect during construction
Throughout the project, there will be machinery, vehicles and active work on site.
Some work will need to occur at night for safety and to reduce traffic impacts on road users. We will inform residents if night work will affect them. Public access to Youngs Crossing Park and the waterhole will not be possible for safety reasons during the construction of the new bridge and road.
We will work to minimise traffic disruptions and inconvenience to nearby properties. All construction activities are subject to weather and construction conditions.
Traffic and road safety
To keep road users, pedestrians and workers safe, reduced speed zones will be in place. This includes a temporary 40 kilometre per hour limit along Youngs Crossing Road. Electronic message signs are positioned at various locations along the project corridor. They will be updated as work progresses.
Motorists and road users should follow signage and instructions. Delays may occur. Council appreciates your patience as we deliver this essential project.
Project delivery and funding
Seymour Whyte is the project’s principal contractor. City of Moreton Bay is working in partnership with them to deliver this vital upgrade. The Australian Government has committed $51.6 million in funding. The Queensland Government will also provide $15 million.
