Problem to be addressed

The Bruce Highway is part of the National Land Transport Network and is the primary north-south route for regional and local traffic on the east coast of Queensland between Brisbane and Cairns.

On the Sunshine Coast, Maroochydore is connected to the highway via Maroochydore Road, which is a major east–west link for tourists and commuters. Just 420 m south of where the Maroochydore Road intersects the highway, Mons Road connects to the highway and provides access for the residential suburb of Mons.

The Maroochydore Road and Mons Road interchanges are congested during peak periods, a problem that is partly due to the short distance between the interchanges. The configuration of this section of the highway also leads to drivers rapidly accelerating and slowing down at entry and exit ramps, which causes unstable traffic flows.

This has led to a high number of accidents, with the crash rate in the project area reported to be more than twice the Bruce Highway average.

Project description

The proposed project aims to address the congestion and safety issues at both interchanges by upgrading the Maroochydore Road interchange, reconfiguring entry and exit ramps at Mons Road, constructing new service roads and widening the Mons Road underpass.

The project has strategic merit, providing safety and connectivity improvements for local and longer-distance traffic on the National Land Transport Network.

Economic, social and environmental value

The project’s major benefits will be for road users through travel-time savings and vehicle operating cost savings.

The proponent’s stated benefit-cost ratio is 3.21, with a net present value of $529 million (7% real discount rate).

Capital cost of initiative as stated by proponent (2018 business case) $301 million (P90, nominal, undiscounted) | Australian Government contribution $241 million | State government contribution $60 million | Private sector contribution N/A
