WORK to widen Marmion Avenue is expected to finish early next year, with landscaping to finish in late 2020.

Contractor RJ Vincent is widening the road to a dual carriageway in three stages as part of a $23 million City of Wanneroo project funded by the State Government.

Next month it is expected to finish the first 1.2km stage in Alkimos, which was fast tracked to provide access to Alkimos Vista estate.

Works on the 2.3km section from Camborne Parkway in Butler to Alkimos Vista and the 8km section from Shorehaven estate to Yanchep both started in April.

Marmion Avenue widening works.

They are scheduled for completion in November 2019 and January 2020 respectively, but will depend on favourable weather conditions and utility relocations.

“The City of Wanneroo greatly appreciates the $23 million funding from the state government, which fully funds this vital project,” Mayor Tracey Roberts said.

“In addition, we welcome the recent announcement of the Mitchell Freeway extension from Hester Avenue to Romeo Road.”

“An upgraded intersection at Graceful Boulevard and Romeo Road will cater for the freeway extension.”

Plans indicate the roundabout at that intersection will be replaced with traffic signals, while new roundabouts are planned at Cinnabar Drive and the future Eglinton Drive.

Mrs Roberts said the widening project would include building intersections connecting to the Alkimos and Eglinton train stations, which would be built as part of the Yanchep rail extension.

She said there would be some congestion during the works, but the majority of works would not require full road closures apart from Darbyshire Parade in Alkimos.

“The advantage of the Marmion Avenue duplication is that the majority of the duplication occurs to the east of the existing road, so two lanes should be operational at all times,” she said.

“The contractor will divert the two way traffic through the new carriageway once it is completed, which will enable modifications to the existing intersections on the west of Marmion Avenue to occur.”

Bus stops will be modified as part of the works, with a bus embayment proposed to replace a controversial Yanchep stop near Peony Boulevard.

UPDATE, May 22: Assets director Harminder Singh said the council awarded the tender to RJ Vincent on March 5, before the Pearce MHR Christian Porter announced on March 8 that the Federal Government would provide $2.5 million for the Shorehaven Boulevard junction.

Mr Singh said the existing plan was to rebuild the T-junction with a southbound acceleration lane in the median island.

“This will greatly assist the traffic turning right from Shorehaven Boulevard on to Marmion Avenue,” he said.

“The City has worked closely with Main Roads WA throughout the development and design of the Marmion Avenue dualling.

“The City will continue to work closely with relevant government agencies to ensure any funding received is allocated to infrastructure that best benefits the community.”
