For years, the Youngs Crossing Road has been a critical yet flood-prone link in Moreton Bay, now, a major upgrade is finally underway to deliver a safer and more reliable route for local residents and commuters.

A Safer, Higher Crossing for a Growing Community

Construction on the long-awaited Youngs Crossing upgrade began in July 2025 following years of planning and community input. A new four-lane bridge will be built at Joyner, west of the current crossing, spanning the North Pine River and Sideling Creek. The existing causeway floods frequently, closing for up to 14 days this year alone.

The project aims to reduce these disruptions and improve access for the 20,000 vehicles that use the route daily. The upgraded road will include safer intersections, turning lanes, and shared paths for pedestrians and cyclists. Designed to withstand a one-in-100-year flood, the new crossing will better support the region’s growing population.

What the Project Includes

The project involves more than just a new bridge. It covers over a kilometre of Youngs Crossing Road, widening it to four lanes between Protheroe Road and Dayboro Road. Footpaths and shared cycling routes are being added on both sides of the road, as well as improved lighting and pedestrian crossings.

New traffic signals will be installed at Protheroe Road, the access point to the nearby pony club, and Dayboro Road. Environmental measures are also in place to protect local wildlife, including fauna crossings and koala-safe fencing.

Construction Timeline and What to Expect

Major earthworks and service relocations began earlier in 2025. With the main construction contract now awarded to Seymour Whyte, residents will begin to see more machinery, temporary fencing, and signage in the area. The work zone is located away from homes and most local businesses, and crews are aiming to keep traffic disruptions to a minimum during the two-year build.

The old crossing will remain open for as long as possible to maintain local access. The full project is expected to be finished by mid-2027, weather permitting.

Local Benefits That Go Beyond the Road

The Youngs Crossing upgrade means more than just smoother travel. For emergency responders, it provides a dependable route that can be used year-round, regardless of weather. For parents and school buses, it means fewer delays and better safety. For cyclists and walkers, it opens up new paths connecting parks and reserves.

And for the broader community, it’s a long-term investment in making local travel safer, faster and more connected. The project also reflects growing pride in the region’s development, with careful planning to protect both natural surrounds and community access.

Petrie and Joyner have been identified for major infrastructure investment under Moreton Bay’s 2025–26 Budget, with projects targeting economic development, flood resilience, and transport efficiency.

Petrie: The Mill Development and Olympic Venue Preparation

The Mill at Moreton Bay remains a cornerstone of the region’s long-term planning, with $100.3 million allocated over five years to continue its staged development. Situated in Petrie and connected by two train lines, the precinct combines a university campus, public recreation space, and land designated for mixed-use investment.

Designed as South East Queensland’s newest landmark destination, The Mill offers extensive opportunity for development in education, employment, and lifestyle. At its core is a vision to support the future growth of the city through inclusive, transformative public and commercial spaces.

Current activity includes road and bridge upgrades to enhance access and readiness for future development. The precinct also features the Moreton Bay water park and adventure playground—an accessible, free-entry facility with aquatic play elements, climbing structures, and interactive lighting displays.

Site preparation has also begun for the Moreton Bay Indoor Sports Centre, which is planned to serve as a venue during the Brisbane 2032 Olympic Games. The broader precinct is being positioned as a long-term generator of local jobs, investment, and knowledge-based industry partnerships.

Joyner: Youngs Crossing Corridor Project Underway

The Youngs Crossing Road upgrade in Joyner is progressing as one of the city’s most significant infrastructure undertakings, with a total budget of $120 million over two years. The project is co-funded by the Australian Government ($51.6 million) and Queensland Government ($15 million), with the remaining investment from Moreton Bay City Council.

This upgrade spans over one kilometre from Protheroe Road to Dayboro Road and includes construction of a new 200-metre bridge over the North Pine River, road realignments, and intersection enhancements. Key aims include improving flood immunity, traffic flow, and emergency access.

Seymour Whyte Constructions Pty Ltd was appointed as principal contractor, with on-ground works confirmed to commence in June 2025. Pre-construction activity has involved relocating services such as sewer, telecommunications, and electricity infrastructure, with power conduit installations ongoing since early 2025.

Additional features include koala exclusion fencing, fauna refuge infrastructure, new signalised intersections, and upgrades to access points including Pine Rivers Pony Club and Youngs Crossing Park. Pedestrian and cyclist connectivity will be preserved with a new shared path linking to Merv Ewart Reserve.

By locating the new bridge to the west of the existing roadway, the majority of works will occur offline to minimise disruptions. Landscaping and environmental design features have also been incorporated to reduce ecological impact, including preserving large fig trees and improving aquatic passage through Sideling Creek.

Strategic Planning and Financial Framework

These major projects are part of Moreton Bay City Council’s $1 billion 2025–26 Budget, the largest in its history. The council allocated nearly $400 million towards capital works to meet population growth and infrastructure demands.

The developments in Petrie and Joyner form part of multi-year programs, with financial backing from state and federal partners in key transport corridors. The projects are designed to address long-term connectivity, flood risk, and employment generation across the region.
