Youngs Crossing upgrade, Joyner

Consultation closes 2 October 2020

Youngs Crossing Road closed due to flooding

Youngs Crossing Road at Joyner 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 will increase to 22,500 vehicles by 2026 and 27,500 vehicles by 2036.

Moreton Bay Regional Council has been progressively upgrading sections of Youngs Crossing Road to four lanes to cater for this growth.

Council is now undertaking preliminary planning and design work to upgrade the road where it crosses the North Pine River at Youngs Crossing. On 2 September 2020 Council agreed to undertaking community consultation on the upgrade. Read the full brief provided to Council. This report includes the background on the project, how the options were selected, the risk and impact assessment and the final recommendations. 

Youngs Crossing 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.

The upgrade will involve constructing a new bridge and associated road works to provide up to 10 metres of clearance above the current crossing.

Council has developed concept designs for two proposed upgrade options and is now seeking community feedback on these options:

Option 1 - Youngs Crossing Road existing alignment

This option involves constructing a new four-lane bridge and associated road works (approximately 940m in length including a 160m bridge) that generally follows the existing alignment of Youngs Crossing Road. The new bridge will be elevated up to 10 metres to provide long-term flood protection.

This route will also involve construction of a four-lane signalised intersection where Youngs Crossing Road connects with Dayboro Road. In this option, state controlled Dayboro Road would require an update in future which is not currently funded.

Option 2 - Andrew Petrie Drive alignment

This option involves constructing a new four-lane bridge and associated road works (approximately 1340m in length including a 180m bridge) to link Youngs Crossing Road to Andrew Petrie Drive. The new bridge will be elevated up to 10 metres to provide long-term flood protection.

This alignment follows the existing preserved road reserve corridor along Andrew Petrie Drive and will connect through traffic to the Dayboro Road/Beeville Road roundabout. This option features two sets of council-controlled traffic signals along Andrew Petrie Drive.
