Client: Clare & Gilbert Valleys Council

Location: Burra Street, Mintaro, SA

Services: Bridge Replacement, Insitu & Precast Concrete Construction, Earthworks, Road Sealing, Guardrail & Pedestrian Rail Installation Description:

Civil Tech Pty Ltd was engaged by the Clare & Gilbert Valleys Council to complete the replacement of the Burra Street Bridge in Mintaro, delivering a safer and more resilient crossing for road users and pedestrians.

The works involved the demolition of the ageing bridge structure and the construction of a new reinforced concrete bridge, designed to modern safety standards and improved load capacity.

Key scope elements included:

• Demolition and disposal of the existing bridge structure

• Bulk earthworks, clearing, grubbing, and excavation

• Insitu concrete base slab, deck slab, headwalls, and wingwalls

• Installation of precast concrete culvert units using specialised lifting equipment, meeting tight tolerances

• Placement of stone pitching and rock scour protection for erosion control

• Construction and sealing of the road approaches, ensuring smooth integration with the surrounding road network

• Installation of W-beam guardrail, pedestrian rail, and TL2-rated approach barriers for enhanced safety

Comprehensive traffic management, including detour signage and site controls, was implemented to maintain community safety throughout construction.

The bridge replacement was completed within a 12-week program, with close coordination between the Council, local residents, and key stakeholders to minimise disruption.

The completed structure now provides a safe, durable, and low-maintenance crossing, supporting improved access for residents, visitors, and freight vehicles in the historic township of Mintaro.
