Perth Street Culvert Upgrade works to resume
Published on 10 July 2026
Toowoomba Regional Council (TRC) has received approval from the Department of Environment, Tourism, Science and Innovation (DETSI) to resume works on the Perth Street Culvert Upgrade project in Toowoomba from Monday, July 13, 2026, weather and construction conditions permitting.
The Departmental approval allows Council to progressively remove an archaeological feature comprising timber elements that was uncovered one metre below the concrete floor of Lake Annand during excavation works in late April 2026.
TRC Construction and Maintenance (Infrastructure Services) portfolio spokesperson Cr Carol Taylor said Council ceased works when the timber was discovered and notified DETSI in accordance with legislative requirements.
Cr Taylor said a detailed archaeological assessment and recording of the elements was being completed, following a preliminary assessment that determined the timber elements could have formed part of a 19th Century creek crossing.
“The project, located on Perth Street between Kitchener and Mackenzie Streets, will replace the existing, ageing culvert with a modern, higher‑capacity structure designed to better withstand severe weather events,” Cr Taylor said.
“The new culvert will improve safety, flood immunity and local road network reliability for motorists, cyclists, pedestrians and nearby residents.
“Road closures and detours will be in place from Monday, July 13, 2026, until late March 2027 to enable the safe completion of works.
“Kitchener Street will be closed to through traffic between Ramsay Street and the intersection of Perth and Kitchener Streets. Access will be maintained for local residents and visitors to Willows Health & Fitness Centre.
“Perth Street will be closed between the intersection of Perth and Kitchener Streets and Mackenzie Street.
“Detours will be in place, with traffic controllers and signage to guide pedestrians and motorists through changed conditions.
“Road users might experience minor delays during the construction period and are encouraged to plan trips, allow extra travel time and follow all signage and directions from traffic controllers.
“Construction generally will occur on weekdays, with occasional weekend and night works as required.
“Council will work to minimise disruption where possible and thanks the community for its patience and cooperation during this important upgrade.”
The project is now expected to be completed in the first quarter of 2027, following delays caused by the heritage discovery.
This $4 million project is funded under the Emergency Response Fund’s (ERF) Flood Recovery and Resilience Package, with $3.35 million provided by the Australian Government and $650,000 provided by Toowoomba Regional Council.
