PALM BEACH TO TUGUN M1 UPGRADE
Snapshot
Demolition of seven bridges in a five kilometre stretch of the Pacific Motorway upgrade project while minimizing disruption to road users. All works had to be staged at night in shifts, with site cleaned and validated safe by an independent structural engineer, by the commencement of morning traffic between 3.30am and 5.00am.

Project Scope
Each bridge presented its own unique challenges that required extensive planning subject to rigorous scrutiny by the key project stakeholders. Plans incorporated break-up of bridge deck, span at a time, management of slurry and bracing for stability before demolition, processing and removal.
Protecting the existing road beneath the bridge was imperative to the reopening of the motorway each morning. Once road closures were established, DEMEX deployed a range of road protection measures including a geofabric lining, track mats, swamp boards and steel plates.
Project Highlights

- All regulatory and project requirements met (environmental, cultural, demolition safety and recycling).
