Works leading to construction of Yanchep bridge to start


THERE are some upcoming changes due to the Yanchep rail extension that residents and motorists need to be aware of including part of Booderee Rd being closed at Yanchep Beach Rd to enable the construction of the Yanchep Beach Rd bridge over the rail line.

The latest Metronet update said a new, temporary Yanchep Beach Rd will be built on the south side, so that traffic can flow freely while bridge works are undertaken.

A new, temporary public shared path will also be built alongside the road to provide continued pedestrian and cycle access.

Another change will result in the shared path on the east side of Marmion Ave being closed between the Brindabella Pwy roundabout and Darbyshire Pde from late October –  signage will be out a week prior to the closure to advise users.

“Pedestrians and cyclists will be able to cross safely to use the shared path on the western side of Marmion Ave,’’ the update said.

Western Power will be relocating overhead powerline services to underground along Pipidinny Rd, so there may be temporary traffic management in place for these works.

There will be frequent truck movements to and from the Alkimos station site compound off Marmion Rd for the duration of the project.

The update said works planned for October include ground preparation for crane pads for deep soil mixing, to strengthen the soil and provide a strong foundation for retaining walls.

“Following completion of the above, retaining wall construction will begin and continue through to late 2021,’’ the update said.

A mobile limestone crushing plant will mobilise to Eglinton station to start limestone recycling operations, to be reused for the construction of roads, station carparks and temporary access tracks.

Excavation works at Alkimos station will continue.

Excavation has started to build the “turkeys nest” or construction dam, north of Yanchep Beach Rd and north of Yanchep station, boundary fencing is being installed on both sides of the alignment, from the station to the end of the rail corridor.

The fauna relocation program is to start ahead of the relocation of grass trees from Ningana bushland.
