- Disaster recovery works on Mount Sylvia Road in the Lockyer Valley are now complete, including extensive improvements to five floodways.
- Works to restore the road to its pre-disaster function commenced in July 2024, while detailed planning was undertaken for improved floodway designs.
- Mount Sylvia Road is now more resilient to extreme weather events.
Major upgrades to five floodways on Mount Sylvia Road in the Lockyer Valley are now complete, better protecting the road from damage and potential commuter disruptions during extreme weather events.
The funding for these major upgrades was provided through the jointly funded Commonwealth-State Disaster Recovery Funding Arrangements.
The Department of Transport and Main Roads (TMR) completed disaster recovery works at multiple locations along this road, which for decades, has been vulnerable to seasonal flash flooding from Tenthill and Blackfellow creeks.
The complex nature of the previous flood damage and in particular, the severe weather events of late 2021 and early 2022, determined the need to create customised designs at each location to find the best value-for-money solutions for repairs.
The construction works included repairs to the road surface, drainage repairs and additional clearing of silt and debris.
Additional works aimed at improving resilience through extended concrete floodways and reinforced concrete road edges, were designed and constructed to better withstand flood events and reduce the risk of erosion.
Rock protection has been added to creek banks and channels to slow water flow, while new landscape plantings will help stabilise the area and support long-term environmental recovery.
Construction started in July 2024 and was completed in September 2025.
TMR’s work complements a major rehabilitation program along Tenthill Creek which was delivered by Resilient Rivers SEQ, in partnership with the Australian Government, Queensland Government, Council of Mayors (SEQ) and Lockyer Valley Regional Council.
Department of Transport and Main Roads Regional Director Bill Lansbury said the project demonstrates a strong commitment to building back a resilient state road network.
“Building back better at water crossings helps to minimise the duration of road closures as well as ensuring the road surfaces are better able to withstand traffic loads when the area becomes saturated with flood waters,” he said.
“These projects help future-proof vital road infrastructure, while supporting environmental recovery from disastrous weather events.”
