CIMIC Group company CPB Contractors has signed a A$330m ($249.7m) contract with Main Roads Western Australia to deliver the Roe Highway Extension (Roe 8) project in Perth, Australia.

The consortium consists of CPB Contractors, Georgiou, WA Limestone, GHD, AECOM and BG&E.

The work includes a freeway-to-freeway interchange at Kwinana Freeway, five interchanges / flyovers, as well as a top-down construction bridge over part of Roe Swamp.

"The Roe 8 project will enhance Perth’s road network operations, improve safety and reduce congestion."

As part of the project, a 5km extension of Roe Highway will be designed and constructed, from its existing termination at Kwinana Freeway in Jandakot to Coolbellup Avenue.

CIMIC executive chairman and CEO Marcelino Fernández Verdes said: “CIMIC and CPB Contractors’ expertise, diverse capabilities and major project experience position us strongly to deliver projects such as Roe 8, and others in the Australian infrastructure pipeline.”

Over the next three years, the contract is set to generate revenue of about A$235m ($177.8m) for CPB Contractors.

CPB Contractors managing director Román Garrido said: “The Roe 8 project will enhance Perth’s road network operations, improve safety and reduce congestion.

“Working closely with Main Roads Western Australia, our experienced Alliance is focused on delivering value for money, mitigating construction impacts and achieving the project’s planned operational, community and environmental benefits through innovative design.”

Construction of Roe 8 is scheduled to begin in late this year/ early next year, with completion slated by early 2020.

The project is expected to create 400-500 jobs during the construction phase.

Further, it is set to reduce congestion, improve freight efficiency and also provide better safety outcomes for all road users.
