Bruce Highway Upgrade - Maroochydore Rd and Mons Rd Interchanges

Project Details:

Maroochydore Road and Mons Road interchanges project included upgrading entry/exit ramps with the Bruce Highway, interchange improvements, new service road connections, new bridge overpass and new drainage structures under the highway, to improve flood immunity in Eudlo Creek.

Key features included:

• Converting the existing Maroochydore Road and Nambour Connection Road roundabout to a signalised interchange

• Constructing a new four-lane, eastbound bridge (two span super-Ts with continuous central pier) over the Bruce Highway from Nambour Connection Road to Maroochydore Road

• Extending and widening all entry and exit ramps to the interchange – including additional traffic lanes to Nambour Connection Road and Maroochydore Road

• Constructing two-way service roads connecting Maroochydore Road and Mons Road interchanges, including eastern and western service road bridges (six-span deck units)

• Delivering new active transport facilities for bike riders and pedestrians through the interchange connecting from Nambour Connection Road to Mons Road

• Widening of Mons Road under the Bruce Highway.

McFadyen's Scope:

• 8,000 metres of drainage pipework across 375-1200mm diameters with multi barrel culverts

• Approximately 300 drainage structures including gullies and chambers

• 270 metres of reinforced concrete box culverts. Core of this scope involved the complex installation of a major 6-cell 3600x1500 culvert spanning 211 metres

• The project was delivered in a high-volume traffic environment with limited access and ongoing coordination requirements around live motorway conditions.

• Works were also undertaken during a record rainfall season, with rainfall levels approximately 11 percent above average, creating consistently wet and challenging ground conditions.

• Maintaining productivity and safe access across multiple crews required tight sequencing and strong on-site coordination throughout delivery.
