CONSTRUCTION to widen Marmion Avenue between Butler and Yanchep is expected to start in December, with the City of Wanneroo recently awarding a design contract.

GHD Engineering will design the 11.5km second carriageway from Butler Boulevard to Yanchep Beach Road in the State-funded $23 million project.

The firm is expected to finish the design to align the extra lanes with existing roundabouts and intersections by August, then the construction tender will go to market.

“The northern corridor is experiencing considerable growth and commensurate traffic pressures,” Wanneroo Mayor Tracey Roberts said.

“We’re pleased to be moving forward with this substantial project that will increase capacity along Marmion Avenue, as well as decrease congestion at intersections.”

Mrs Roberts said the upgrade would improve traffic movement between Yanchep and Butler via the arterial road network.

Works are anticipated to begin in December and finish about January 2021.

According to the City, earthworks, kerbing, drainage, street lighting, shared paths, landscaping and pavement construction works will require a substantial amount of coordination.

“Complex traffic management will be in order to ensure the job can be completed safely while the existing carriageway of Marmion Avenue is still in operation,” Mrs Roberts said.

“Whilst some regular road users may be disrupted, the long term benefits to our residents will be immeasurable in terms of reduced commute times.”

The City is consulting developers adjacent to Marmion Avenue, as well as utility providers, to understand the impact of their current and future infrastructure obligations and to avoid potential duplication or sacrificial works.
