Robinson Street Mittagong Culvert Renewal

Project typeCulvert Renewal & Road Pavement Reconstruction
Project scheduleJuly 2024 - November 2024

The project addressed an installation of box culverts and reinstate 50m section of road pavement at Nero St and Robinson Street intersection. The project upgrades will prevent a major flooding event for Robinson Street. The road surface itself has been enhanced with better drainage systems, leading to improved water quality run-off. Pavement reconstruction has been undertaken and a durable asphalt sealing surface has been laid, extending the road's lifespan. Safety features have been upgraded with new signage and guardrails for increased driver confidence. Environmental considerations were also addressed through grass seeding, and slope protection measures.

Project works

Works for this project commenced in mid-July 2024 and were completed ahead of schedule in November 2024. The works included:

Box culvert and headwall installations
Pavement reconstructions
Safety fence installations
Bank stabilisations, tree removals and re-vegetation

Background

During February and March 2022 flooding events, the run-off from the creek significantly damaged stormwater pipes, headwalls and road pavement at the interface of Robinson Street and Devon Street Mittagong, and the road and bank channel have been subsequently eroded. The creek water should be discharged efficiently by constructing a drainage structure and around 50 m section of eroded road pavement should be reconstructed. The renewal of the culvert and associated works are a part of the disaster recovery works.

Community impacts

Road users and pedestrians were made aware of heavy machinery and workers in the area during the works. Changed traffic conditions and exercise care when travelling through the work zones, approved through a Council Traffic Management Plan. Access to emergency services have been maintained during construction.
